How to add Power heated seats 2003-2007 sierra silverado avalanche escalade with ANY wiring harness

[@afterduskstudios]

So we can grab any harness ( fully loaded gmt800 with heated/leather etc seats ) and wire in what we don’t have … and then anything extra just close it off?

[@joeydally8581]

I just got wiring harness that runs from driver to passenger seat.do I just splice the wires in where they come from under the dash and from the doors and splice the wires that go to the back doors. Any info would be appreciated. Thanks

[@Nordic_Mechanic]

First thing is splicing or plugging into the big connector under drive side dash. Follow the wires to make sure they go to the same place especially in the module with yellow plug under the driver seat. My harness was different because it came from a different bodystyle (avanlache/escalade) so yours could plug in. There's not much going to the back door but thats where you splice the purple wire. You may have unused wires too. driver front seat ground connection (big black wire) may also need to be connected to a ground depending where the harness was cut

[@stacyadams4386]

Did you have to add any factory fuses (under the hood, side of driver dash)? I put a floor harness and to the seats I wanted to keep the manual seats but wanted heated. As soon as I turn on the heated seats it turn right off within a second

[@Nordic_Mechanic]

I already had the fuse in because I had electric seat base from the factory. What exactly do you have? you found heated seat that are not electric? What's your year truck and the year and style of seats. The factory heated seats turn off if the heater in the seats are bad. But Id like to know what you actually did to see if it could be the problem.

[@stacyadams4386]

@@Nordic_Mechanic 04 sierra 1500 I went to the junk yard and grab the floor harness and the same junk truck grab the harness from the seats. My wife has 03 Yukon with power seats and they are junk thats why I want to keep the manual seats I got the heaters working apparently the switches for the driver and passenger heaters talk to each other because now they're working I didn't have the passenger switch plugged in the 1st try thanks for trying though

[@wagoneer401]

Veikra - thanks for the great video. So it’s possible to add the necessary rpo (AG2 &AN3, I believe?) to the BCM to get the memory and easy exit to work? It can be added to the existing BCM that currently doesn’t have it? Who or where can tbis be done? Thanks!

[@Nordic_Mechanic]

Yes, you need someone with a tech2 to add it. Or you can send your BCM to a company that will flash it in. I never bothered to, I never move the seat anyways and heat works

[@ryancurtis5109]

I have a set of power heated seats from a parts truck, and friend of mine has manual seats but his drivers seat has a harness under it like yours, will the directional power buttons on the drivers seat work just from plugging it in ?

[@Nordic_Mechanic]

Yes. Hooking the big orange and the big black wire is all you need for power function both driver and passenger. Heated seats wont work without the full install shown here

[@ryancurtis5109]

Veikra thanks for the quick reply, hopefully seats are from a 04 2500hd and he has a 05 2500hd...plus I still have all the wiring it’s just not pulled from the truck yet just hoping the power to the drivers seat for the time being will be simple thanks again

[@patrickperry1079]

Hey buddy my name is Patrick an I'm doing the same swap on my 03 Duramax an I would like to ask you a couple of questions if you don't mind I took the wires out of the doner harness that needed an installed them into my factory harness pin for pin the only wires i have left over that are not hooked up are a pink wire, yellow an brown with a white stripe that went to the doner harness at the left front kick panel plug do I need to splice them into my factory harness or are they not used also everything works other than my heated seats on both sides im not sure what to do any help would be much appreciated!

[@Nordic_Mechanic]

hard to tell which wires those are. As I said in video, the color changes between model and years. For instance, my harness is avalanche instead of sierra so almost no colors. Can you make a video and show both harness? Its been years since I've done mine

[@carsandcoins]

Can you please make an update video ? I have the same truck as yours and it has no heated seats . It does have the base electric seats . They are cloth . If I want to add full power , heated seats would I have to change out door panels and the harness to the door ? Please send me more info on this

[@Nordic_Mechanic]

this is all you have to do for the door panels. This is the cheap option without buying new door panels. Just cut and put the switches in. They connect to window switches. kzbin.info/www/bejne/pJzTcmahmZqdm8k The rest is in the video, but be attentive or you may miss some details. This tutorial works for any harness, dont have to have a perfect sierra to sierra match, although that would be easier

[@ClayVanGieson]

Does anyone know what the purple and brown connection are for that go to the BCM and fuse panel? Just installed a donor harness that didn't have these but had factory heated seats. Wondering if all I need know is a factory door switch to turn the seats on? Do I need those two plugs for the heated seats to work? Any help is greatly appreciated.

[@Nordic_Mechanic]

2003 and up do not require any door harness. The switch in the door connects to the window switch and uses the CANbus to talk to heated seat module

[@ClayVanGieson]

@@Nordic_Mechanic do you know what the purple connection that went into the bottom of the BCM is for? Same with the brown connection that was with it that went to the fuse box on the side of the dash.

[@ClayVanGieson]

@veikra, do you know if I need the purple and brown connection to get the heated seats to work? I bought a switch and it has power, but no orange lights for the heat. Thanks.

[@ClayVanGieson]

I installed the harness out of a 03 into my 05. I bought the factory heated seat switch and connected it into my door switch. It has power just not the orange light for heat. Do I need a different BCM? Or do I need to reflash the one in the truck? Any help is much appreciated

[@anthonymurray8451]

Buying a 2013 Avalanche with cloth seats. If I buy a used junkyard front leather seat with heat and air, are the wiring there to plug in the used seat? Hoping they make one wiring harness for all the trucks. If the plugs are there, will the controls then be on the display?

[@Nordic_Mechanic]

I havent done one of that generation but it should be the same or perhaps simpler. The settings wont show on display until reprogrammed though. For instance, I dont have the memory seat working as I didnt recode the bcm . I still have heated seat working as specced out so im happy and all the motions of the seat work

[@mattheintzelman4147]

I’m doing the same swap as you, and your video is has been very helpful. I merged the harness and everything works seat wise all 8 position. On both dr and pass. But my heated seats don’t power up I see that they get power but they don’t light up or turn on. Any help or advice would be so helpful

@@Nordic_Mechanic 2006 Sierra 2500 Duramax, had power driver seat with manual recline, full console, bose, power everything else I swapped the seat harness from the loaded truck. It dings when I press 1 and 2 and some other button. Heated seat symbol illuminates but when I press to turn them on nothing happens

[@Nordic_Mechanic]

@@Matt_logann You seem to have a problem with the routing of the blue wire. Check the video section about it. You have to make sure it goes where it used to go. You BCM is receiving the command from the door switch as it dings, so the blue wire from the bcm to the seat module under the seat is where your problem lies

[@Fogarmj]

Great video. I have been studying it trying to get my power/heated 2003 denali seats swapped into my 2004 silverado 1500. I pulled an entire harness from a 2003 Avalanche but instead of swapping the entire harness, I just tried to add the connectors to the seat harnesses that were missing from my 2004 factory harnesses. I added the orange power and black ground to the passenger seat, the orange ran back up to the driver's kick panel relay box C10 harness. I just inserted all the female pin connectors into my harnesses. It is mainly wires that run between the drivers seat connector and the passenger seat connector. In my diagrams, these are all the wires that were in the avalanche connector that were not in my connectors. I can't find a wire that runs into the yellow airbag module that you are calling the blue wire. Can you give me details on this blue wire? what is it actually called in the circuit diagrams? I added the door switches and I get them to beep when i press the memory button but no heated seats are working. I feel like I am missing a simple wire that is needed but I just focused on the 2 seat connectors.

[@Nordic_Mechanic]

you get the beep since the switch are using the window switch for can bus connector. But you still need the can bus of the new seat module to communicate with the bcm. That's what you are missing, the can-bus link

[@Fogarmj]

I figured it out. You were right! I had forgotten to add the can bus wire back to the harness. I hooked it up and everything works. Thanks for the help.

[@ReubenNewton]

@@FogarmjI’m trying to do the same from a 2003 Yukon with dual power and heated seats. My 2004 only has driver power seats. From what I understand, I need to get a harness for the passengers side and of course the controllers from the door panels with associated wires that run through the rubber boot. Does this sound correct to you?

[@Fogarmj]

@@ReubenNewton you don’t need the full harness. There are maybe 6 wires you need from a donor harness. The control buttons in the door simply plug in to the window control panel. I can walk you through it. I have the wiring diagram you’ll need because mine is an 04 also.

[@ReubenNewton]

@@Fogarmj Thanks for the reply! I’m excited I don’t have to pull the wiring through the door, that was the part I was dreading. I’m going to be giving it a shot over the next few weeks to see if I can get it done.

[@gunnarkintigh8172]

So can I not just swap the harnesses out Becz I have a Chevy Silverado crew cab that doesn’t have heated seats and the other truck I have is a avalanche and it has the center console and heated seats I can’t just swap the harnesses over and it won’t work?

[@Nordic_Mechanic]

Won`t exactly swap over. This is why I made the video . It shows the few places you have to modify in order to retrofit the avalanche harness into your truck. You'd need exact model and year to straight plug in and airbag option might still be an issue at the module under driver seat, on the floor.

[@gunnarkintigh8172]

Gotcha well I took the entire harness out of this avalanche and was gonna like try to plug and play? And maybe get my body control module re flashed to get my memory for the seats?

[@jorr4744]

If I get the wiring harness and seats from 06 escalade use it for my 06 Tahoe is it plug send play because I have power seats just not heated and memory

[@Nordic_Mechanic]

most likely. Otherwise do what I did with that connector

[@740iz06]

Do you have a pen out for the seat connectors wondering how many wires from the driver side need to go to the passenger side and then how many wires need to go from the driver side to the dash have pieces of a harness and seats trying to work with having a hard time finding a connector view

[@Nordic_Mechanic]

You can get the pinout at the dealership if you ask nicely, but due to a hard drive crash I dont have it anymore. orange and black are 12v and ground respectively. That will make the seats move . The others are for airbags and heated seat / memory. You're losing valuable time without a full harness. Cut off after the b pilar. My method works with all truck 03-07 , easy to come by harness in a junkyard.

[@gerardojuarez6938]

Did your truck come with the switches on door panels? I have a single cab I have seats & harness but I was doing a bit of research & it said that I needed the harness from the door so it can hook up to the switches

[@Nordic_Mechanic]

No, I installed them in a previous video. You dont need harness in the doors if you have a 2003-2007 They work on canbus, plug in the window switches

[@gerardojuarez6938]

Oh ok. I think I do need the window switches from 03-07 cause the plug for the heated switch doesn’t plug into the one I have now from my 01

[@Nordic_Mechanic]

@@gerardojuarez6938 It wont work. This video is for 2003-2007. You have normal electrical system, you need wires. I thought since youre messaging me on this video about 2003-2007 you had one. 2001 is a totally different system. You'll need way more wiring and harness than this

[@gerardojuarez6938]

Yeah I was thinking the same. I have the seats & the harness but I haven’t had any time to take it to somebody to wire them up & I had one guy telling me I need the heated switch to work on my door panel

[@joeydally8581]

Veikra do you have a better wiring schematic on how to wire up donor wire harness to existing plug

[@Nordic_Mechanic]

No, theres no way to tell what donor and vehicule everybody have. Many combinaisons exists. Thats why what Im explaining in the video is important. It shows you how to make sure the donor has everything going the correct way. I remember you from last year. Do you have factory radio?

So I have a 2005 GMC Sierra 1500 single cab that has manual windows locks and seats. I want to swap the interior out of a donor 2006 Yukon Denali seats and locks and windows can I take the harnesses and bcm from the Denali and swap it over? Will anything need programmed?

[@Nordic_Mechanic]

you cannot swap bcm. Needs to match ecu and instrument cluster in programmation. hardly required if you dont want the memory seat and easy entry features. Heated seats are stand alone, meaning if they can talk on the communication bus to each other, theyll work. Pretty sure the required wires to plugs the yukon doors are there on both side of the dash and ready to go. Couple wires to check like the blue wire in the video to make sure it goes the right way and the power and ground to each seat . Other than that your golden

Do you know the connectors part number so that I can cleanly connect power to them and splice in power to the passenger side? I've been looking and can't find it.

[@Nordic_Mechanic]

Passenger side power is already connected if you used a donor harness. it runs over the transmission tunnel and under the seat. Find the big black wire on the passenger seat and connect it to ground and it will work. If you dont have the harness then connect large orange wire to 12V and big black wire to ground. If you want heated seat you're better off finding a harness

Did u have to make a custom harness on passenger side or did u just leave the two harnesses unplugged and the heated seats worked?

[@Nordic_Mechanic]

I had no harness on the passenger side. I used the new one and had to connect in the sill panel (same plug) as shown plus a ground. It`s 100% how it would have been from factory.

[@jordanfereira4823]

I just did this conversion to my 2004 gmc sierra duramax. I used seats out of a yukon and the harness from a 2004 escalade. I have the seats working except the passenger seat heater will turn on for about a minute or so and then shut off. I believe it is just a bad element within the seat but I also did not connect another ground wire to the drivers side post. I don't know if that is affecting anything. My larger issue is that since I did all this wiring my gauges, radio, windows, and door locks went wacky. It went back and forth from not working to working (over the course of about a day). Now everything is working (I'm thinking the body control module had to relearn with the added functions) except my body control module has lost communication with the transmission control module. The TCM is functioning and the truck still shifts but I lost my trans temp guage, the shift indicator and tow/haul switch lights up but does not function. Do you have any ideas of what this could be. I didn't think this harness had anything to do with connections between the TCM and BCM. Any help would be much appreciated!

[@Nordic_Mechanic]

Id look at all the wiring, then the module under the driver seat. This module communicates with the bcm through the canbus. any short or any module connected to can could hog up the serial bus and cause other device to not be able to communicate. unplug the computer, see if it does anything different. then unhook the harness from the footwell and see if it comes back. There is no garantee your seat module is good. But for it shutting down it's usually heaters. Without the ground, you won't have the power seat working on the passenger side. If you do, itd check where the thick black wire goes. (The thick black wire beside the orange one in the connector) Can you post a video?

[@jordanfereira4823]

I found two black wires that went to a ground point further in the escalade harness that I had cut. I attached those wires to the ground point on the post next to the drivers seat. They had no effect on anything. I still have no transmission communication. The escalade harness did have a back up sensor module on it that was past my cut point. I am wondering if that has anything to do with the loss of tcm communication. To my knowledge the two wire twists are part of the can bus network? I see there are some of those that I had cut thinking I didn't need the rest of the harness. My other thought on this is that it could be my body control module since the TCM is working properly other than no communication. Now that I think of it the BCM has been acting up over the past 6 months to a year. Little things like the radio not shutting off after opening the door, the chime not stopping after removing the key from the ignition, the doors not activating interior light. Could the added seat control module have pushed the BCM over the edge?

[@Nordic_Mechanic]

yes the 2 grounds you found I also cut. my harness was escalade as well, and there is a big orange power wire going to the back. Make sure it's properly capped off. Unplug the harness at the junction box near the brake pedal . If it does nothing, you may really have a bad BCM. But please check all the wires going to it for any signs of rubbing on the bracket. Sure sounds like a BCM trouble now

[@jordanfereira4823]

I've figured it out! Yesterday I swapped BCM's with my buddies truck. My BCM functioned properly in his truck and his BCM had no effect on my issue. Then we swapped TCM's. My TCM in his truck produced the same no communication issue. His TCM in my truck illuminated the shift indicator and the transmission gauge. Unfortunately my TCM is bad. It is an expensive fix but at least I know what the issue is. Thanks for your efforts.

[@Nordic_Mechanic]

Alright so at least it's unrelated and you didn't break anything doing the swap. It's just unrelated wear!

You need to program if you want the MEMORY seats as I said in video. Because that works with the bcm when you remove the key you can have the seat pull back to give room . The heated seats work on their own. You hook it up and go, no fuse to add either.

Hey man, ive been studying this video as if i were to take a test nd im not confident enough to do this myself. I have an 06 silverado 1500 crew cab 4wd with power driver nd manual back. Passenger is all manual. Back glass is the 3 piece which i really hate. I got lucky at the junkyard nd got both front full power leather seats, both door panels with swtiches, nd i got the harness. Same exact truck execpt with it being an 05 nd having a solid one piece back glass. I saw tht the thick purple wire hooks to the back glass for defrost. Other than the back glass nd seats... its the identical style truck. The module under the seat of tht truck was corroded bad nd literally welded itself... so i jus snipped tht off. Do ya have an updated wiring video or have something else to follow ? I understand everything going on till ya start cutting the connector nd splicing the oem. Thts where i get lost nd with hooking up to existing module. I dnt wanna burn out any modules or sensor because tht can become more or a pain to fix ! Also under my passenger seat i have a wire i believe its the black one thts connected to the airbag nd it throws a service airbag code

[@Nordic_Mechanic]

You are right, purple is defrost. I recently broke my rear window and found my truck had rear defrost. So the window in the truck is not original. For the module under the seat, it's the airbag controller. The connector I replaced is because the seat and wiring came from a different truck, namely, a avalanche. I just made sure the wires would trace back to the correct truck wiring from the new seat wiring. The wire under the passenger seat I mentionned in the video and IIRC its the ground of the seat. Airbag of passenger seat goes back to right side kickpanel. It plugged right in in my case.

I want to install powered seats into my 2006 GMC Sierra extended cab work truck. I thought it would be simple, but after reading past posts I see I was delusional. I don't have the powered seats yet. I found 2002 seats but have held off on purchasing them. Would I be better off using seats of the same year as the truck? How about airbags? Will they still function? Another option I was considering was just changing the seat base and keeping my current seats.. Any advice and direction would be much appreciated.

[@Nordic_Mechanic]

Lots of info in the video but if you want seemless install like I did, you can't use 2002 in a 2006. The truck generation split in 2003. so keep 1990-2002 and 2003-2007 together. The 2003 are totally different wiring wise, canbus and all. That's why I was able to simply plug in the heated seat module in the doors, and they send command through the serial bus to the module under driver seat. Airbag will still work if you follow the video. Also said in the video is if you dont want heated or memory, all you need is to connect the orange and black of each seat. If you take the seats from a same year model you can simply plug in everything and it will work minus the memory seat (require bcm prog). I used seats from a different platform and year. Thats why my wiring was so different. I have 2005 truck, seats and loom from 2003 avalanche with rear entertainments.

Hey Sorry Veikra one Last question, so for this swap did you use the BCM? Because I swapped a harness and No BCM and I still have an airbag light...

[@Nordic_Mechanic]

No, im using stock BCM. Airbag light is something else. For instance, could have a bad airbag in the seat causing problem. Also, do not plug in the connector for the side airbag if your old seat didnt have a side airbag either. Scan the airbag module. It will narrow down your search. If it wont communicate you have a wiring issue. If it does communicate then it will tell you whats at fault. It is NOT a bcm problem. As I said before, if you are unsure , check the harnesses side by side. Some pins could be different althought same year and model seems unlikely. Just not impossible since the 7 way seat have more stuff to them that the other.

[@williammclaughlin2606]

@@Nordic_Mechanic harness was identical, old seats were electrical with air bags. I will scan them I’m hoping it’s just one of the sensors or air bag.

[@Nordic_Mechanic]

@@williammclaughlin2606 maybe one of those airbag in the new seats have a bad igniter so it's at fault. Otherwise the heat works?

What is the single purple wire for? From your trucks harness

[@Nordic_Mechanic]

I believe it's for the rear cablight

[@michaelblackhurst2854]

Hey, what colours go to what on the plug you had to cut? I tried to screen shot, but still can’t really tell. Thanks !!

[@Nordic_Mechanic]

the twisted pairs are pretty much all the same color except one pair. You see a pair with a green wire, you connect to the pair that has a green as well. The positions in both connectors are similar too. There was also a blue one, which when to another blue. It's related to the rear radio and center console subwoofer so not critical. DO NOT HOOK UP the side airbags wires if your truck didnt have them . Thats the wires I taped off

[@michaelblackhurst2854]

Veikra thank you, I got it figured out. Everything works except the heated & memory seat part. I watched your other video but I still haven’t figured it out.

[@Nordic_Mechanic]

memory will not work until you get bcm programmed. The heated seat should start working after a few key cycles. also make sure orange and black wires have power

[@Nordic_Mechanic]

do you hear a beep in your speaker when you press the memory buttons?

[@michaelblackhurst2854]

Veikra few cycles of what? No beeps but I have an aftermarket radio(if that matters). When the key comes on the little lights come on but nothing when I press the buttons

[@claytonspade9292]

Doing the swap now have all the power working just worried about my airbag pug under the seat the nee harness has less wires then the old one,what do i have to do?

[@Nordic_Mechanic]

your new harness has WAY more wires and thats normal. the locating tab with not let you plug into the module right ?

[@Nordic_Mechanic]

I misread your comment, that's supposed to be the other way around. The new seats have airbags in them, and thus that airbag module plugs of the new seats will have more wires. Which model truck and year do you have, and in what did you take your seat and harness?

[@claytonspade9292]

Correct my truck is a 05 silverado 1500 with the basic cloth seats and i just picked up a set of seat for a gmc 2500 probly around the same year

[@Nordic_Mechanic]

@@claytonspade9292 Sorry, missed a few comments with youtube acting funny. But can you send me pictures of both connectors? the harness from the new seats should have more wires but it can all be fixed since you have both

[@ericizgayformen]

My truck is LT1, with leather seats but only 4 way power on driver side, all manual on passenger like you- and no Bose and manual heat control. Will my BCM work with this swap? It’s my understanding you didn’t need to do anything with the BCM but your truck did have more options than mine like heat and Bose so I’m not sure.

[@Nordic_Mechanic]

Technically it should work. The BCM has nothing to do if you dont go for memory seats. The window switch simply relays the info on the CANbus and the module under the driver seat picks it up and turns on the heated seats. It's kind of neat

[@stang1966gt]

Wow a lot of work! I am looking to convert the manual passenger seat to power (no heat). Best just to run power over from the driver seat? Good job with the upgrade

[@Nordic_Mechanic]

yes, power the black and the orange and you`ll be set. It was quicker than I thought and totally worth the effort considering the cold climate I encounter

[@591films]

I can't seem to find a donor harness. Does anyone know if GM still sells the complete harness? I know they used to.

[@Nordic_Mechanic]

it was crazy expensive, I think I said it in the video but I dont remember 100% 400$ or 800$ or something. And you can use any harness from 2003+ with the top option seats. (heated and memory) Look in scrapyard for suburbans and tahoe, they pop up more often in scrapyards in full options since top of line pickups are rarer per production numbers. I see the seat removed, but the harness is always there. I wonder if the suburban at my local junkyard is still there, he had the correct one but I didnt have tools on me

[@mrcee6512]

Extremely cool and helpful video bro. Have you ever replaced one of the drivers side heated elements? I believe mine just went out. Anything feedback would be great. Thank you and have a good one bro.

[@Nordic_Mechanic]

I've not had to replace any element on this one. Usually the bottom element is the first to go out. Did both of yours go out at the same time? Are the passenger side ones working? The lights on the button should flash to indicate a problem

[@mrcee6512]

Veikra it's usually intermittent. I believe the drivers side bottom element went out. Passenger side works good til I turn on drivers side. I know the bottom heat elements go out 90% of the time. I was just curious if you replaced any because you seem very knowledgeable. I have an 04 cadillac escalade 6.0

[@Nordic_Mechanic]

I was sure I had to replace at least the bottoms one, as these seat came out a 2004 escalade. Did not have to, it's not THAT bad to do, just need to take your time and be a sticker for detail when putting back the leather in place. So far so good, 2 winters, still toasty warm ! Only use the 2 and 3 light for warm up, then only on the first one.

[@mrcee6512]

Veikra you're lucky bro haha. Keep me posted, if you ever do a heat element share me the video if you choose to record it. Merry Christmas bro to you and your family.

[@Nordic_Mechanic]

thank you, ill try to find a broken truck to do it

[@SpartanAutoworx]

If you can find a Vin for a crew cab diesel with heated seats and memory I can program a body control module and send it to you. I'm sure any crew cab with heated seats and memory would work but I rather take some variables out of the equation.

[@Nordic_Mechanic]

I can find a VIN number easy, all canadian ones driving around have that option. and VIN number is viewable under the windshield. I want to keep my current BCM because I know it's good and know what it's been through. Where are you located?

[@SpartanAutoworx]

Veikra St.Louis MO I can send you one pre programmed or you can send me yours and I can program it.

[@Nordic_Mechanic]

Can you do a window switch program as well ? I have one for a escalade and need it switch to my truck for power extending instead of power folding (mine got killed by water )

[@Nordic_Mechanic]

I have vin of 2004.5 truck with the option, can you leave me your phone number?

[@danielreed7872]

Does it have to have the same features? For example, I’m trying to add just the 8-way heated and power seats with memory as well as the door panels with the buttons. I want to keep my flip down bench seat console and do not want to add the center console with rear A/C. Is that possible? I have a VIN of a diesel crew cab same as mine except is has those seats and door panel switches and center console. Are you able to make that work?

so what do you actually need if you just want the heated seats to work? I've got the heater power seats from a 2004 suburban into my 2004 2500hd silverado and i just hooked up the power and the ground.

[@Nordic_Mechanic]

you need the heated seat buttons , and the harness from the truck you took the seat from, or any truck with the heated seat option between 2003 and 2007

[@GustavoMartinez-ob3jy]

did you have to do any programing?

[@Nordic_Mechanic]

no, but you need programming if you want the position memory

[@mossman381]

The 2500hd has the heated seats and I love it but not sure it's worth that much work. Maybe an aftermarket heated seat kit.

[@Nordic_Mechanic]

aftermarket have cheap looking and feeling buttons. Not worth it. This was very straighforward especially since I did the research for you guys. And my method broaden the amount of vehicules you can get the seats and wireing from. My truck looks and feels like it came out with the option from the factory. All you need are the seats, harness and buttons. Plus if you get the harness from the same year and model, you dont have to splice anything. only takes an afternoon

[@mossman381]

Veikra I guess if you could find a plug and play harness it wouldn't be too bad. Then you need to find heated seats I am guessing from the same year. Still a lot of unknowns. You did the 03-up. I have 2002.

[@Nordic_Mechanic]

yeah, so you have 1999 to 2002 1500 and 2001-2002 3500 to choose from. Get the harness that came with the seats. I had more work to do because I didnt use seats from the pickup variant, nor the same years or same airbag options.

[@AddieB15]

Did you get the memory seats working yet? If so, how did you do it?

[@Nordic_Mechanic]

requires BCM (body control module) reprogramming to add the function. Haven't done it since Im the only driver. heated works without programming anything

should be plug and play unless it has different airbags, then you have to shave the red plastic cap in the yellow connector under driver seat

Did you ever do the swap?

[@skyyy5150]

If the seats you have now are 2 way and the ones you are getting are 8-way, unfortunately you gotta swap the harness

[@dreamstomper6612]

Literally just go buy a set of donor seats, take the seat harness from under the carpet, and the door cards. To the average person that’s way easier than doing all this haggard shit and exactly what I did so the only real hassle is peeling the carpet back to SWAP a harness, not create a fire hazard in my cab….
