GM Truck OEM Off-Road Light Switch Install

This video shows how to perform a factory installation of an off road light switch and wiring in a GM Truck(Sierra/Silverado). It also works for Canyon/Colorado trucks. Your BCM should have come from the factory pre-programmed But early models may not have.

[@arcamediuas]

@@joncunningham7672 I have a 14 Sierra, correct me if I'm wrong but you don't have the offroad cluster icon, so you may not have to run to the bcm, but rather use it like switch to initiate a light bar(or whatever). Use a relay and fuse power from elsewhere

Hey, thanks for getting back to me, that’s very cool of you. I have watched your video probably half a dozen times, it’s great. What I’m trying to figure out when I watch it is. I’m trying to add a Light bar also. I have the light switch with the dual buttons on the bottom. In your video, you hooked up your light bar to the button on the bottom right, I’m trying to use the button on the bottom left. My Oem sport bar lights are hooked up to the bottom right button. What do I do differently to use the fog light (left) button for the light bar?

[@josephedwardmartinez]

What did you say had to be done if we wanted to keep the light bar stay on with the high beams on? I have a 2019 GMC Sierra 2500hd Denali diesel. Great video and will make my life so much easier with this professional install. You’re the best. Thanks.

[@James.d.thomas]

This is an amazing video. Couple of questions if you don't mind. I recently bought a rebuilt 16 2500HD Silverado that came factory without fog lights but when they replaced the front bumper they added them at my request. I can't find a harness online that hooks into the lights and I am wondering if there are already plugs in the truck somewhere for them? After seeing this video I looked up this switch but couldn't find it for a Silverado in any trim level. Did they make this switch for the Silverado? Where did you find all the X port information to know which wire to add where? Thanks. I'm gonna have to check out this channel. Again, great work on the video.

[@kevefox]

@robertedgemont I was thinking about that last night actually. There was a vehicle approaching that would not be in their highbeams so I try to hit them with my lightbar but only ended up turning off my fog lights. I was thinking that the reason it is a long process so that you don’t make that mistake and accidentally dial somebody when you’re trying to just turn on your fog lights

[@scotie100]

First off great video. I do have a question I have a gmc sierra sle 2016 and I want the ability to turn on the fog lights with the drl lights. I currently have the same headlight switch that you replaced with the new one. So would i f ollow these same step buying a new head light switch and add the two wires you did without the jumper wire for under the hood? Any help would be greatly appreciated.

[@davidromanowski8092]

Tinkering Fox would this harness work for a 2017 Silverado? How would the harness work?

[@VanLoweLawnCare]

Im assuming this switch would still work if you dont have factory fog lights on 2016 1500 WT? I definitely want to do this and eliminate the dinky stick on switch that came with my pods. I also wonder if I could just use existing wiring that I ran into the cab for the pods?

[@stormshockin]

@tinkering Fox This is for the next chain that will likely continue on a few months. It's great to know there are options for a truck that basically came standard stock with out a lot of features! I'm a low voltage tech, so I understand a thing or two, but I've never built a harness and don't like splicing wires. (And a mechanic. I tear all my engines down.. currently working on the Oil Pump on this 2014.... the front diff is being a bit difficult though.) But, at least this should serve to state that I should be able to comprehend everything you instruct me to do.

[@kevefox]

william vaughn sounds good 👍🏻 the main reason for my camera upgrade is to display trailer TPMS on the radio display. I figured the front camera will help for parking and the third brake light for fifth wheel hookup. The mirror ones are just a gimmick but why not.

[@stormshockin]

@@kevefox Yes yes yes! And I saw that Alpine does all of that. But it's SOOOOO Costly!!! So, I'm working with a local audio/tech company called Waxwerks here in Indiana to try and set me up with a nice in-dash that has all the options so I can add on little by little as my budget and time allows.

Would you know if there's a way to wire with the OEM light switch with dual auxiliary buttons.

[@kevefox]

Yes, there are a couple ways...with a latching relay: kzbin.info/www/bejne/oWXYfmSVYsSCqpI Or with programming and then adding some wiring...www.whiteautoandmedia.com/product/2015-2018-canyon-colorado-wams-spec-bcm-programming-autosync/ www.gmupfitter.com/pages/body-builder-manuals

Excellent video. Is there additional wire that needs to be hooked up to run both aftermarket fogs and ORL? I have a '18 GMC 2500HD that did not have fogs from the factory. I have purchased a light switch, lights, and the described harness from Harness Dr. I have not attempted the install yet as I am still deployed.

It is a different connector for the other style. I pulled that right off of the still frame pics of the directions in the video. I’m not sure what document number the directions are at this point. They were for a Colorado/Canyon but are identical for Sierra/Silverado. I haven’t seen any that use ones different from the video.

[@nathantrammell7471]

With that off-road swift, can you have one button do the light bar and then wire up ditch lights to the other button?

[@davewarriner2575]

@tinkering fox, finally a video on some circuit mods. I'm in need of some help though as I'm rather new to the electrical world. I just did a new bumper install on my 18 silverado 1500 which removed the fog lights essentially. However, the hookup from the lights is still there just not being used now. I want to hook up some offroad LEDs (one bar and 4 cubes) but want to keep the factory look on the inside so am curious if I can hook the lights into the fog light's existing wiring and have the interior switch work inside. I worry about the overall draw on the existing set-up or if this will blow a fuse or something along those lines. Any advice on how to set it up without having to install new switches on the dash?

[@kevefox]

Dave Warriner thanks! ‘16+Up should be programmed for this. You have a few easy options. This is a cheap option for your dash. This is a GM part but the indicator light on the button won’t light up but other than that it’s perfect and $100 less than the one currently on sale through GM. rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F263473206828 I wouldn’t hook up more than two cubes in place of your fogs without using a relay. Also your fogs turn off when your high beams are on, here’s the fix for that..... www.gm-trucks.com/forums/topic/162734-foglights-on-with-high-beams/ Next do you have harnesses for your lights? Meaning did they come with relays and such? Third there is a slick way to make your led bar/cubes come on with your high beams but only when the headlight switch is in the “on” position not “auto”. I’m going to do a write-up/video on this really soon on my ‘17 2500. I’m ordering the bar/mount tonight. The output from the BCM for off road lights is positive but only strong enough to trigger a relay.

[@davewarriner2575]

@@kevefox yes three harnesses one per pair of cubes and one with the bar. The switch currently installed already has fog light option, which isn't being used at the moment, is the upgraded switch necessary or can I tie into the one I already have. That's what I thought about the relays so could I some how strip the three switches that come with the harnesses and splice them into the factory installed fog light switch?

[@kevefox]

Yes, absolutely. That will work. These work really well for cutting through fog. You could run these wired to the fogs and the others off of the ORL switch. www.quadratec.com/products/97025_04X0_PG.htm They’re Amber

[@michaelmcclure1835]

Awesome job, fully detailed explanation for complete install. What is the amperage or biggest light you can put on that circuit?

[@kevefox]

Thanks. The circuit should only be used as a trigger wire to trigger or switch the relay for your off road light.

[@arcamediuas]

Great video. Oddly enough I was looking at doing something similar to my 2014 sierra(gas) but wiring for smoked roof lights+side step markers(I've blacked out the Denali grill with some black housing stock looking headlights; so it'd look sick!) I know I don't have the cluster icon so I wont bother running to the bcm, but do you think that i should be able to get ignition power off the existing switch connector, and use that offroad switch second button to initiate the markers/roof(wouldn't require a hold?)? Also I like what you did with the amber light bar, might run a separate branch circuit and copy that! And fyi, I have seen some of your other videos and like what you're doing, the ignition relay video(and the garage door opener programming, lol) was well informing and plan to do a similar thing to run an air compressor, air horn and other goodies! I'll keep following.

Great video!! thank you. does the switch latch to the high beam on a 2018 sierra? I work in the bush and have my light bar wired in my high beam trigger right now. With the switch on, the light bar will only come on with the HB, switch off, no light bar. I want to keep the same set up but would love to use this OEM switch. I refuse to drill holes in my dash, so my light bar switch just sits loose in my cup holder...

[@kevefox]

The only thing that this switch does is creates a positive output signal. On my wife’s truck I did what you want trying to do. With the OEM switch on the highbeams will activate the off-road light relay. If the switch is not on the highbeams will not activate the off-road light relay. I’m going to do a video and Install sometime soon for a local in my area where I will do exactly what you were talking about. The highbeam signal is negative so it will work on terminal 86 of the relay and your positive signal can go to terminal 85 of the relay for the off-road lights. The only downfall is that some lower quality relays will backfeed and illuminate the off-road light icon on the switch itself so a diode in line is preferred

[@lawrencenick88]

I know that you posted this video in 2018, however I’ve just spit recently.

I have this switch but the lights on the sport bar are connected to the button on the right. I would like to do what you did and hook up a light bar using the button on the bottom left on the switch.

[@kevefox]

I’m assuming that you don’t have factory fog lights? Since the signal is momentary you’ll need to convert it to a constant signal. Here is a video showing how to install this switch when your truck doesn’t come with fogs or the programming for the ORL function....kzbin.info/www/bejne/oWXYfmSVYsSCqpI. You can also add factory fogs. You’ll have to add the BCM programming though...www.whiteautoandmedia.com/ this too will require wiring.

I have a 2018 GMC sierra and I'm looking to leave my original switch in there and wire my light bar up to the fog light switch and then wire my fog lights to be on all the time like DRL I was wondering where you got the wire diagrams for the connecters on the fog light delphi connecter and the JCT to show the pin outs

[@kevefox]

Search GM Document #4573588. Any dealer can print them for you too. There is a Colorado fans page with a quality PDF of them. Another option you have is to just tap into the fog light signal coming from the switch. A momentary press of the switch will turn on the fogs while a longer press will turn on the fogs as well as the ORL. You can then quickly press the fogs again to turn them off leaving the ORL on. You just need to run a second wire from the fogs signal over to the ORL input at the BCM. The dash icon will illuminate and the constant signal will come from the ORL output from the BCM to your relay.

I have switches in the truck for both, but looking to go to an oem look. Any suggestions on how the wiring would work?? I’m thinking I need to just route a signal wire from the switch in the dash, to the relay.

[@kevefox]

cdahlman10 If your truck is 2016 and later the Offroad light button will work because the BCM should have programming. The switch puts out a momentary signal and the BCM will convert that signal to a constant positive output for triggering a relay for your lights. The fog lights however our different, if your truck did not come with them then the BCM will not latch that signal. There is a way to do that however. Email me, tinkering [e-mail] and I will send you a link to a video I am working on that is not public yet which will show you how it’s done.

[@MT-xp7qo]

Awesome video! Just like everyone said, this is a professional install and really appreciate the walkthrough. I’ve got a 2015 High Country and ordered the harness through Phil, but my RC light bar has a high and low beam on the toggle switch and two relays. The toggle has red, white, and blue wires. Together the red, blue, and trigger wire turn on the high setting, the red, white, and trigger turn on the low. Also, the amber light on the OEM off-road switch does light up, but pushing it and holding for 3 secs doesn’t control the light bar. I just want the high beam to run on this light bar when I push the off-road lights, but I’m stuck. Any thoughts?

[@kevefox]

Hi there. Thank you. Your 2015 won’t have the programming for this mod. Only 2016 and later. Here’s a workaround for ya! kzbin.info/www/bejne/oWXYfmSVYsSCqpI Also there are three wires going into the RC light bar, one is ground, one is light bar power and one is DRL power. Wire both power wires together. The high beam signal at the BCM can be tapped into and used as the negative side of your relay trigger (86) and the signal from your latching relay (positive) can be used as the positive trigger (85). The first few minutes of this video will give you a solid foundation on how the relay for your ORL works…..kzbin.info/www/bejne/g6fZiXp5l6Zoj68

[@MT-xp7qo]

@@kevefox Thanks so much! I found your workaround video last night and it is so well done. The only other question I have now is related to the two combined relays with this light bar. Three wires from the toggle switch enter one relay, and wires to the light bar exit the other relay. Assuming I leave them together and just focus on the toggle switch wires, combining the power wires like you suggested and connecting to the trigger wire, once I have the BCM workaround setup fixed. My back up is connecting them to an 8 gang panel I have, but really want this OEM off-road switch to work lol

Awesome username! So I assume you also want to add fog lights? The BCM should already be programmed for the ORL even without being built with fogs. There is a different switch that has blue background light with only the ORL button that would be an identical install. PN:23458496 (Blue background with ORL button, no fogs) If you wanted to add both fogs and ORL you would use a different switch with both buttons... PN:23458492...updated to PN:84168423 (Blue background with both ORL and Fog buttons) Adding fogs is much more involved if you want to make it factory. Without BCM Programing you’ll need to use a latching relay to convert the momentary signal from the fog button to a constant one. Then use this signal to control a relay for your fogs. If you want to keep it as factory as possible then there are some color coded circuits to run under the hood to and from your X50A (under hood fuse block). Otherwise just use the output from the relay to power your fogs with a widely available harness from eBay. Thanks for watching, more videos to come discussing this

I did everything just as you said, same connectors, quadruple checked it, still nothing out of the yellow wire going to the relay

[@josephedwardmartinez]

Question, I have a light bar with Day Time Running Lights (DRL). I’d like for the light bar Day Time Running lights to come on with the fog lights. How best would I connect without sacrificing too much of the “factory” wiring? I’ve already installed the OEM off-road light switch and cabling but didn’t consider the possibility of DRL at the time. Please help!

[@dpsmedic]

@tinkeringfox - great video. Just came across this. Will this also work with a 2019 Colorado ZR2 Bison with Factory Fog lights to add a light bar?

[@ryanlogan2911]

You beat me by 10 hrs. I have a ZR2 and in process of installing ARB winch bumper & want to run the running lights and off-road lights from the factory switch.

[@kevefox]

Yes, the instructions are actually from a Colorado/Canyon.

[@cafox567]

I am working on this same project right now! However, I want to add fog lights to my truck using the same switch you have but I can't find any wiring diagram for 2016+ or newer. Do you have any info on that?

[@kevefox]

Nice! The BCM will need to be programmed as well for them to function factory. White Auto And Media Services can help with that.... www.whiteautoandmedia.com Here is another link to the GM Upfitter page..... www.gmupfitter.com/files/media/photo/664/Sierra_Silverado_Electrical_Body_Builders_Manual_Service_Manual_2016_en_US.pdf You can find all the schematics and diagrams here.

Is there a similar process that can be used to add fog lights to a truck that didn’t come with them? (2018 Chevy WT). Would be nice to be able to use a factory switch, and have light in dash light up.

[@kevefox]

You can add factory fogs but your BCM will need to be programmed and you’ll need to add some factory wiring. Good news is you can program your BCM at home.....www.whiteautoandmedia.com/product-category/autosync/

[@ARios-kq9fh]

@@kevefox Unfortunately, I've been trying to give my money to WAMS for a while now; but no luck. Their AutoSync doesn't work with the IOB radio, which is what I have in my truck. They used to do the physical programming that included flashing the BCM for fog lights; but they don't do that anymore. I bought a WT. Guess I should learn to live with a WT.

[@scottferrell8423]

Do you know if this would work for a 1500 or would that be a different part number if so would you know or be able to help Mel find the right part number for a 1500 for 2016 ?

Yes it will work for 1500. Just make sure to get the right backlight color.

[@elden8785]

Is this the same hook up on the 2016 Chevy Silverado 5.3L do you have the wire diagram or is it the same as your video I have the same switch now and the wire harness .

[@docholliday6635]

Would like to try that on my 2016 but it's a base model..be my luck I'd spend all that to find BCM isn't programed. Your vid was good but I still have some questions. But I'll review a few times to muster some courage.

[@kevefox]

Sorry for the late response, really long work day....you can apply a long ground signal to the pin that goes from the Switch to the BCM using a wire inserted through the plug.

[@bryanh2646]

Hey TF. Great video! I have a 2018 Denali HD Pickup and ordered the new headlight switch and the harness from the harness doctor. What a time saver. Question. How can I defeat the bloody seatbelt minder on this. Without cutting or destroying anything. Obviously I can get a buckle and just plug it in but you might have a fix? Also - I’d like to have my trailer lights available other than just park and neutral gears. Any suggestions?

[@kevefox]

Thank you! You can just unplug the seatbelt wiring under the seat. Today I towed a Duramax out of the Highway Patrol impound. I towed it in two weeks ago for the investigation of a fatal accident where it was traveling over 60 NB and was struck head-on by an F150 traveling SB at over 70. I had a ten minute conversation with the driver who was relatively uninjured. Without a doubt he would have been killed if he wasn’t wearing a seatbelt. Neither truck caused the wreck. A third vehicle came from a side road and pushed the F150 into the Duramax. There was zero time to react. As far as the rear facing lights go, they are disabled while in forward gear for obvious reasons. You could add a latching relay to the same circuit, bypassing the BCM. You would have to use diodes to prevent backfeeding into the BCM. kzbin.info/www/bejne/oWXYfmSVYsSCqpI

[@bryanh2646]

Tinkering Fox don’t worry. I wear my seatbelt. But we do stuff in the ranch and towing boats all at low speeds so it causes an annoyance that’s all. On regular streets and highways the seatbelt is strapped., believe that.

[@bryanh2646]

TF, so I just finished the install of the new headlight switch and the harness, just as you documented. I have a 2018 Duramax truck, and low and behold the little backlight behind the overhead button works! I am having some issues though. I’m not sure I like the “press and hold” feature, unlike the fog lamps which are instant on-off. A few observations: Sometimes when I push and hold the cab (off-road) light switch, it does not activate. Also sometimes when I push it, it does not deactivate. I have the most success with on-off when I push and hold BOTH fog/cab switches at the same time. In some cases, the only way for me to turn the cab lights off is when I cycle the headlight switch to off. Bizarre! Any suggestions and again, sorry to bother. Great work you do!

[@kevefox]

@@bryanh2646 I’m going to be installing a light in a ‘16 Yukon soon. I’ll be making it a two part activation. First activate ORL, then turn on high beams. This will be my fourth install with this two part system. I’ll do my best to make another video.

[@homercan2]

What if... we have the All Terrain X, that already came with the sports bar, but no lights from factory? I already bought the switch, what about the wiring? Would I have to wire from the switch, to the bcm, through the boot?

Hey great video but apparently I’m an idiot. Just got the switch completely wired. Was hoping to test the switch before beginning the work under the hood. Any reason the dash light wouldn’t turn on even after pushing and holding? Does the relay and off road light need to be fully assembled to complete the circuit?All other switch functions seem to work.

[@kevefox]

You need to have the key on and the headlights need to be “on” or be on due to low light conditions like in “auto” with the photo sensor on the dash covered. Do a long press (several seconds).

[@chrisk164]

[@zr2_elite438]

I have a quick question, I recently bought the sport bar with factory lights off Craigslist for my 2019 ZR2, I plan on buying a new OEM switch and using your harness you made. Only thing I'm missing is the harness to run from lights to This. Can you please recommend a harness I can use to complete this set up please.

[@kevefox]

This one will work. You’ll need to cut and splice more length in. You’ll also need to disconnect the switch from the harness and apply your BCM output wire to the wire that is intended to return from the switch that comes with this harness (going to the relay trigger) www.superbrightleds.com/moreinfo/wire-harness-relay/led-light-wiring-harness-with-relay-and-weatherproof-switch-dual-output-dt-connector/1979/ There is also a circuit you’ll need to interrupt at the X50A (Under-hood fuse box) going to the third brake light/cargo bed light.

Can you tell me which of the two white plugs in the BCM you tapped into? I have a 2016 Silverado 1500 - have the switch the wire harness, but trying to get the hook up to work. I have two white plugs in the BCM: one right next to the brown plug (which already has OEM wire in slot #12) and another on the end of the BCM, closest to the brake pedal (and slot #12 is open on this one). Just trying to verify for sure which plug I need to try and tap into.

I have an ‘18 diesel Colorado and my OEM switch doesn’t have the light ring around it, nor does my dash have the additional orange light indicator left to the green fog light indicator.

I believe it will work. You can unplug your fog light signal from the switch at the BCM and plug it into the ORL circuit to test the programming just to see if the icon pops up on your dash. www.gmupfitter.com/files/media/photo/629/Escalade_Escalade_ESV_Suburban_Tahoe_Yukon_Yukon_XL_Electrical_Body_Builders_Manual_Service_Manual_2016_en_US.pdf.

[@guysteel]

Could this switch be used without even going into the BCM. Just using the switch as a switch to trigger a relay without going through the BCM? I'm guessing the BCM is only being used to light the indicator in the dash. Does this sound right. What is the voltage through your gray wire? 5v? or 12V? Thank You.

[@guysteel]

OK, success, I got the switch ( hard to find) and the correct harness and followed your instructions and DONE. I works with my 2017 Silverado 2LT 1500 and matches my blue background lighting of my truck. I'm not sure if you mentioned it but the off road part of the switch is a LONG PRESS, both for on and off. The orange indicator does light up on the dash and the switch when the off road lights are on. I felt the numbering on the white BCM connector was a little screwey but I carefully followed the video and everything works perfect. Thank You.

[@slapper223]

Hey TF! Thread bump! No seriously, several years back I installed the EXACT same dual function GM switch on my ‘18 Denali HD EXACTLY as you described here (still a great video btw). The only aspect I’m not in love with, is the 2 to 3-second press and hold ON/OFF function of the “off road lights” part of that switch. The fog light button is, of course, instant ON/OFF. So my question is - is there ANY way to to wire it in such a way to acquire the instant ON/OFF function of the bottom right button of this switch?

[@kevefox]

Hi there. Yes there is. I hated that too. I used the positive output to trigger the positive side of the relay (85). I used the negative high beam signal from the BCM to the X50A as the negative trigger (86). It’s the wire that comes from your BCM and goes to the fuse block to activate high beams. You will have to first activate the ORL by long pressing the switch, and then turn on the high beams to trigger the off road light. If you pull the high beam lever (flash to pass) the ORL won’t light up so you’re not blinding oncoming traffic if you just want to remind them to dim their lights.

Sorry but for the infant electrically minded - the high beam signal you mention Brown JST X5 pin 18? And if so do I just splice into this wire and connect it to the blue trigger wire (86?) on the relay? Not sure if I’m replacing these connections or merely tapping into them.
