2017-2019 Super Duty SEIC/High Idle Installation Instructions

10,000 views! Thank you all so much folks. It may not seem like much but for me that's huge!
My very first instructional video. Here I'm installing a Stationary Elevated Idle Control/High Idle Kit into a 2018 F-350 6.7L. Will work for any 2017-2019 Super Duties. The chart given does not state any Wattage values for the resistor. Chart only states for 1200rpm a 19491 Ohm or 0.971 Voltage resistor is required. Actual measured on installed resistor is just over 20KOhms.
If your looking for the 2020 setup, I finally have my Instructional Video for install out. Check it out here;

My pass through wires are not visible like yours. I can only see 2 pigtails that barely stick out of the fire wall and can't even get my hands on them. On the inside of the panel their isn't much either. Is that right or am I missing something or did Ford just screw me on those wires? Any help is appreciated!

[@LifeofRaiden]

Hello, I will try to help as much as I can! What year is your specific vehicle? Also, the harness maybe be quite thoroughly taped to main harness, so much so it may not be visible. Does your harness have "extra" tape in that area?

[@LifeofRaiden]

Oh and what engine? 6.2/6.8/6.7? Edit; Saying location will differ slightly depending on gas/diesel.

[@jlweck231978]

2018 6.7

[@jlweck231978]

I think I just found them but they are all taped up. They come out of the tape and loop back into the tape. I don't know what end to pull on and hate to un tape it all.

[@jlweck231978]

Ah i do see some black electrical tape down there. I think that is holding them down. F' could they make it any harder. I am worried about reaching down there my arm is really pressing against the connector for my computer. Is it okay to unplug it or will it throw some things of unhooking it?

[@herveyforward5956]

Thank you Shamus for the teachable explanation. I had to look long and hard to find the 1 then blank then 11 on the housing. However by counting I found the CORRECT YELLOW AND GREEN STRIPE, Why the caps! Well because as per other videos that dont tell you the pins you can easily ( 50/50 shot ) grab the OTHER yellow and green # 18 and then when you mock it up ,put it all together and you get a big fat WTHeck? nothing. I also used WAGO connectors inside the truck as it miserable to work in however it is clean and dry. They work fabulous positive lock or unlock no wire damage, no voltage drop and if you get 2- two slot connecters you can then insert the green and the white with brown and then snap in or out different resisters. If you wish to or remove the wire job easy and clean. I used one on the pass through wire also. Outside I’ll use weather pack connectors. 2019 Ford F-250 6.7

[@LifeofRaiden]

Haha oh really?! I'm glad the video helped! Thanks for the update too, that sounds like a great way to do it and easy to modify if needed. Very much appreciated!

[@ArmendF150]

Thank you sir, this saved me money dealer was gonna charge me $250 like wow for such a simple job it cost me $1 to buy The 20k 1Watt Resistor and less then 30min to install it lol...And its way better with Aux 1 then having a dial on your dash or whatever this way I can set it and forget it all I need is 1200rpms which is perfect. It was done on 2019 F350 Platinum. Cheers 🤙🏽

[@LifeofRaiden]

You're welcome good sir! So glad I could help! Yeah, I've heard some outrageous prices for install. As for the dial, I have ideas to make it look good. But its more for someone with varying needs. Again, thanks for the great comment and I'm so happy to help!

[@MrJuventino451]

I finally got it rolling on mine. So i connected #18 yellow/green to solid green with a 12k resistor. Then power to #7 yellow green. Works just fine now. 2019 F250 XLT with 6.2l gasser

[@LifeofRaiden]

Right on, thanks for the info!

[@kennethhampel3589]

Great video thanks!!

[@LifeofRaiden]

Thanks! 😊

[@dashcam3098]

I done this to my 2017 f350 when I purchased the truck and passed the wire at the same place as you did across the fire wall with loom cover just as you did, but the heat from the engine melted all the loom . I had to purchase heat insulation to protect the wire from the manifold heat. Did you have an issue with your loom over the wire melting.

[@LifeofRaiden]

Oh really? I haven't had any issues so far. I've had one where after some time the loom got brittle but the wire was intact and not melted. Thanks for letting me know, I will keep an eye out for any that!

[@peterlucas6732]

I'm gonna give this a whirl on my 2019 F250. Thanks for the very thorough instructions!

[@Trigger_32]

Great thorough video. Very helpful! Actually able to tell exactly what you did, which was a nice clean install. Plan on doing this to my 17 6.2L.

[@LifeofRaiden]

Thank you very much! Sorry for the shaky cam (got a handle now haha). I recommend reading thru the comments as well, some great ideas! Any questions just ask!

[@Trigger_32]

Thanks but Ive got no questions for you. I do however have intel for you. The resistor table for gassers is different. For 1200 RPM they call for a 12K resistor. The pin out is also slightly different. The SEIC 12V input is still the same as being a yellow/green wire on pin 7. The PTO RPM input also stays the same as a green wire on pin 9. The PTO VRef is where the difference is. It becomes a yellow/green wire on pin 18. All this info with wiring diagrams can be found in Ford's SVE Bulletin Q-256.

[@LifeofRaiden]

Awesome! Thanks for the info, I will look that up!

[@MrJuventino451]

@@Trigger_32 i'd like to do the same on my 2019 gasser. Did you get yours to work?

[@Trigger_32]

@@MrJuventino451 I did. Set it up using the Aux 1 upfitter switch

[@joshuasmith4882]

I have a 2018 f350 platinum and I followed yours and another guys video to a T. I can not get mine to work at all. Used aux switch 1 and ran it over to the white pass through. I then hooked the 7pin wire to it and put the resistor on the green and white/brown wire. I have messed with it for 2 days testing wires and resistors with a multimeter and still can't get anything to work. Any help would be greatly appreciated.

[@LifeofRaiden]

Very odd. Ok, I'll look into this a little. In the meantime, a couple basic questions. Have you made sure you have a known good relay for Upfitter 1 as well as made sure the fuse for the Relay hasn't been popped. Last question, I must ask... you have the parking brake engaged and not touching the service brake when trying to activate system?

[@joshuasmith4882]

I'm not a 100% the switch is good but when I test the pass through wire I do have l power. I'm guessing the fuse/relay is good, because when I tested the wire & fuse with my light probe it lights up. I do have the parking brake set and no foot on the service break.

[@LifeofRaiden]

Oh yeah that may do it. Does the lettering light up when you use the switch?

[@thefartdart]

I thought the uplifter wires are the same in the Eng, compartment and the kick-panel ?

[@LifeofRaiden]

Ok, so I'm REALLY hoping KZbin is being wonky in telling me this comment is from 3 years ago... I just uploaded a video and your comment as well as another popped up from 3 months ago. If indeed you commented 3 years ago, I'm so very sorry for not seeing and responding to it. If not and KZbin is being wonky, then to answer your question; There are technically some similar wires from the upfitter wire box to the connector at the kick panel. However the functions are not the same. God I hope it's not from 3 years ago. Again I deeply apologize if so.

[@johnm9131]

@Shamus if I don't have up fitters couldn't I just run a toggle from battery voltage to the yellow and green?

[@LifeofRaiden]

Oh good question. Let me double check and get back to you tomorrow. I dont want to give a definitive answer and have steered you wrong. Will triple check the wiring diagram tomorrow and let you know asap!

[@johnm9131]

@@LifeofRaiden Thanks

[@LifeofRaiden]

@@johnm9131 Ok, so I've looked into it and yes you can totally install a toggle switch from the battery to pin 7 ye/gn wire. I do however suggest circuit protection as well. I've double checked the wiring and fuse diagrams. The stock circuit protection for the output side is 25A. So as long as somewhere you install an inline fuse with 25A, you should be ready to rock! Hope this helps. Any other questions, ask away!

[@johnm9131]

@@LifeofRaiden thanks for getting back to me I really appreciate it. I do plan on using a fuseable link. Appreciate your time and videos. Are you the "electrical guy" at the dealership or "diesel guy"?

[@wiredforstereo]

I wish you could have told us what the labels were on the 7, 9, and 10 wires were, in case ours were different, since I have a 2020.

[@LifeofRaiden]

Yes, I totally understand. When I posted the video, the 2020 models were not out yet. I will be posting a video soon for the 2020 models but that wont help you now. I will check tomorrow morning and update you ASAP!

[@LifeofRaiden]

Ok, I've looked it up and customer access pigtail wiring for the 2020's do not change from the earlier models. Pin 7 is the PTO1, Pin 9 is the RPM PTO and Pin 10 is the PTO REF.

[@wiredforstereo]

@@LifeofRaiden Thanks for the info. I got it working. But now I have a strange clunk from the transmission when it disengages.

[@LifeofRaiden]

Really?! Interesting, just making sure. Your 7th pin YE/GN is going to the pass thru wire then to upfitter relay box wire. And the resistor is installed at the 9th pin GN wire to the 10th pin WH/BN wire?

[@LifeofRaiden]

Also too. I am literally recording the 2020 High Idle video now. I just found that the customer access pigtail at the BCM has two YE/GN wires. Pin 18 and pin 7. Can be tricky, I just got caught with that myself and accidentally wired it to pin 18.

[@justmessingaround9492]

Worked good if you like to simplify Just put the two yellow and green wires together you won't need a switch just put the parking brake on good to go 👍

[@LifeofRaiden]

I'm a lil confused. Which two wires are you connecting? Also, without the switch, does that mean the RPM's immediately increase when the parking brake is applied?

[@justmessingaround9492]

Off the harness there is two yellow with green stripes wires One is hot and the other one is switched if you connect them as well as using the 20k resistor are you have to do is apply to The parking brake and Hi Idol is activated

[@LifeofRaiden]

Oh ok, I've never tried that myself but yeah, sounds like a great idea! Thanks for the info!

[@sungun5312]

I have a resistor between wires white/brown and green. I've also connected both the yellow and green wires together and have found that this does not work on a 2018 superduty 6.7L

[@LifeofRaiden]

Oh really. Ok, thanks for the confirmation!

[@rcmike38]

The pass thru harness is factory installed by ford ? Thanks. I’ll go look for it on my 19 f350

[@LifeofRaiden]

Yes, all should have those ready to go for you. At most they may/will be taped to the Main Harness, so might be a lil hard to see initially.

[@TexasBR549]

Where can I find the resistor at?

[@LifeofRaiden]

Well, I myself got a pack of them at my local Radio Sh... lmao. The Source now. If you're not in Canada then any local electronics store. Or even a hobby shop (R/C sorta thing). They my have a selection?

[@bearb1asting]

Sad only good truck videos exist. My transit is never gonna work

[@LifeofRaiden]

Oh no, really? I've not had an opportunity to install on a transit. What year/model? I'll look into it tomorrow. Are you having a specific issue or just installing it in general?

[@bearb1asting]

@ShamusLife 2020 pre March. It comes up to 900, kicks the relay, stsrts to ramp up then kicks out and goes back to idle

[@LifeofRaiden]

@bearb1asting sorry for delay, was doing some digging. Haven't found anything specific yet. Is there an install kit or is it just stock?

[@bearb1asting]

@@LifeofRaiden all of the Ford documentation is wrong. It has 5v on green violet, goes to green white, and only needs 12v + on PTO request 1 (green) to engage.

[@WilliamBelvin]

Thanks, Will this work for gas also?

I haven't physically installed one into a gasoline vehicle, but yes it should all work the same. Checked the wiring diagram and they all seem to match. Any other questions, just ask!

[@MrJuventino451]

Yes it does

[@TheRcCrawlerKing]

Its gotta be watch time cause most people are gonna watch a tutorial till the end. Also car repair and DIY is very popular subject to dive into. Lots of people looking for info on here these days.

[@LifeofRaiden]

Sweet, thanks for the info man!

[@HollywoodBush]

What size gauge wire? Just trying to get together a parts list so I can go to my local electronic store.

[@LifeofRaiden]

I'm not at work at the moment but I'll check tomorrow and update. If you're in a pinch, there are two options. Easy way is if the tag on the customer access pigtail at the lower interior A-Pillar is still there. There may be gauge info. If not, unfortunately it's get your wire strippers and match to gauge numbers.

[@HollywoodBush]

Thanks! Just was curious if you knew. Did you end up soldering or using butt connectors?

[@LifeofRaiden]

Ok, I've scoured the wiring diagrams and pigtail printouts. I'm seeing gauges 18/20/22 used at the customer access connector. I cannot confirm pass-thru wire gauges, no actual printed documentation stating gauges can be found. With that being said, I know there are a couple wires at upfitter relay box and pass thru wires that are 16 and/or 14 gauge (can't tell ya which exact ones, sorry). As for installing, I myself soldered. I found that when using resistors, the metal tabs may/will break or become weak when using a but/crimping type of connector. Hope this helps, any other questions just ask!

[@jmcaulay182]

which gauge wire did you use? @@LifeofRaiden

[@LifeofRaiden]

@@jmcaulay182 For this installation I used 18g.

[@libertysporting3894]

Very helpful thank you. I might add a pot for variable RPMs and a 680 ohm resistor to keep it from going too high if it is bumped. Also, thinking of running at least 4 wires from the up fitter relay to the pass through area through the loom, just so that is ready for future use.

[@LifeofRaiden]

Thank you very much! Yes, a potentiometer would be the best component to install for the varying load requirements the vehicle may need. That protection resistor is a fantastic idea as well. Also, when your run the four wires, I highly recommend trying to match wire gauges as some are intended for a higher load. In this video, the customer requested only this. Therefore, I could not take it to a higher level. Thanks for the input and great ideas!

[@Mr.J345]

On the sheet it states 1watt resistor is that what you used?

[@LifeofRaiden]

Justin Jelley I'm not sure off hand the wattage of the resistor. The chart that came with the pack only stated the Ohms available. I had to go thru all of them to find the closest to 20KOhms. The actual resistance of the installed resistor in the video was just above 20,000 Ohms. I don't have the chart in front of me right now unfortunately. I will check tomorrow morning and update video description accordingly, sorry for delay.

[@Mr.J345]

No rush I want to do the same thing to my truck just wasn’t sure what resistor to get thanks for the reply.

[@LifeofRaiden]

So I checked the chart. It doesn't say an exact wattage for specific resistor. 1 watt looks to be the general spec and for specific RPM is depending on total resistance. Hope this helped!

[@justmessingaround9492]

Worked good if you like to simplify Just put the yellow and green wires together you won't need a switch just put the parking brake on.
