How To Easily Wire A Lightbar Or Other Accessories To Your Super Duty Upfitter Switches!

The wiring applications shown in this video, will be the same for most light bar installations on any vehicle. Main difference is with vehicles aside from Super Duties, you will probably have to use your own switch. Unless of course, your vehicle has spare switches from the factory.
Main thing to note, is DO NOT power a light bar off of your factory high beam circuit! You can overload and damage your body control module and ruin it, or with older vehicles you could possibly have a fire. Use the factory circuit as a trigger for the relay only!!! Your auxiliary lights need to get their power from their own circuit. In my case, that is with a 25 Amp switched circuit.
For 2011-2016 Super Duties, your headlight wire colors should all be as follows:
Driver side:
High beam - Gray with Brown stripe
Low beam - Brown with Blue stripe
Passenger side:
High beam - Violet with Orange stripe
Low beam - Blue with Green stripe
Upfitter switch wire colors and amperage are as follows:
Aux 1 - Yellow - 25 Amps
Aux 2 - Green with Brown stripe - 25 Amps
Aux 3 - Violet with Green stripe - 10 Amps
Aux 4 - Brown - 15 Amps
You can make a wiring harness out of supplies from literally any auto parts store. I would actually recommend this over buying a harness off Amazon or wherever. Those tend to have 16 gauge or even smaller wire, and I would not personally use them.
So far I am very happy with this light bar for being only a 20”. It is stupid bright for the size and the money. If you want to get one for yourself, you can find it here -

Keep in mind if you are using it on a truck like mine, you will need to create some type of bracket using some small pieces of flat steel.

Thanks for the great video. As previously mentioned, drama free. I understood the principles, but the hands-on straight-forward approach makes it click. Much appreciated!

[@akgearhead]

Great to hear!

[@curbythevan]

Nice! Our van is down for repairs at the moment so I bought a 2014 f250 extended cab and I'm looking for simple upgrades to make it more functional. Thanks man!

[@akgearhead]

Heck yeah!

[@GordFreeland]

Thank you. Both your videos on uplifter and, light bar wiring rocked and helped a ton. Thanks again. 🤙🏼👌🏼👍🏼

[@akgearhead]

That’s great to hear! Glad they helped. Thanks for watching!

[@TMCityCenturion]

Awesome follow up video. I installed upfitter switches back in the summer with the help of your upfitter install video. Finally mustered up the courage to cut holes in my bumper to install some auxiliary reverse lights, and this video had all the information I needed. Thanks for sharing

[@akgearhead]

That’s great to hear! Extra reverse lights are a huge upgrade on these trucks. Makes such a difference being able to see. Glad the video helped!

[@davidlouiso9650]

Thanks for sending me this tutorial. You’ve just made my life/install so much easier. Thanks for being drama free!

[@akgearhead]

Heck yeah man! Glad it helped!

[@nautilus4335]

Thanks for this. I'm trying to teach myself how to do something similar on a 2021 ranger tremor and this feels like the best first step i've found so far

[@akgearhead]

Glad it helped! The concept of how the wiring is done is virtually the same for any vehicle, so hopefully it gives you a good place to start.

[@FiveBoroNative]

Extremely helpful video...! Keep 'em comin'...!

[@hockeyman2274]

Good video - I need to do this to my '19 F250.

[@akgearhead]

I’d recommend it! The headlights on the alumaduties suck too unless you have the non peasant factory LEDs

[@tcwhite0104]

OMG i finally found mine, the Upfitter switches were already attached to the relay/fuse box found left side underneath the steering wheel comparment area. Had to pull the cover off and there were the 4 wires coming out of a wire harness bundle.

[@akgearhead]

Sweet!!!

[@Foxriverfarm1]

Looks like it was a plow truck in the past. They taped the left turn yellow and brown running lights green right turn.

[@akgearhead]

I wouldn’t doubt it

[@user-hn6dd5re6o]

Where did you find the brackets to close in your gap for the mounting brackets? Just got a 24” bar and I’m dealing with the same issue of needing more surface to mount to than what I have between the frame. Thanks in advance.

[@akgearhead]

Just some pieces of flat steel with holes drilled for mounting

[@yamilpaez5625]

Thank you for the video is very helpful. I want to ask how I can install a led strobe light at top and 2 at the front and two at the back thanks

[@akgearhead]

Just saw your comment on the other video. So to do strobes, I’m guessing you’ll want the strobes to come on independent of anything else, so what I would personally do is mount them up, ground them, and then run your power wire directly to the upfitter switch of your choice. Super easy how Ford has it set up for us, and that’s really all you’ll have to do. Most involved part will be just routing the wires. If you want the top strobe to come on separate from the rear strobes, just run each to a separate upfitter switch. Hope this helps, and let me know if you have any questions!

[@yamilpaez5625]

Thank you I’m going to try this Ty for the quick response

[@yamilpaez5625]

So do I remove the upfitter switches and wired my lights directly to it or would it be under the steering column

[@akgearhead]

@@yamilpaez5625 the power wire for your strobe light will connect to one of the wires that go to the upfitter switches that I show in this video. Being as yours had them from the factory, I’m not 100% sure where Ford will have the ends at, but most likely tied up somewhere under the dash. You will NOT need to remove the upfitter switches to do this. Once you locate them, just choose the color you want depending what switch you want them to go to. I believe you should have the same color wires that I have. Strip back the sheathing from the wire, and then butt splice your power wire for the strobe directly to it. Then all you will have to do to power up the strobe, is to flip your upfitter switch on. Your ignition will have to be on of course

[@yamilpaez5625]

Thank you for all the info! You should do a video on doing service to this truck, like I said before I just bought a 2010 f350 yesterday and really don’t know anything about it yet lol

[@tcwhite0104]

GREAT VIDEO!! I can not for the life for me figure this out...call me dumb.. lol My 2005 F-350 DRW FX4 had factory aux switches and have a black wire harness inside a black plastic conduit that seems to go up to the firewall area, the switches outside are red/black/blue/white. There isn't a label on the harness either showing what wires are what....GRRRRR Freaking Ford.

[@akgearhead]

I couldn’t tell you what is what on an 05. Never done any wiring on one of those trucks

[@pooh40]

So the uplifters are powered. We just have to ground it to the chassis... for light bars???

[@akgearhead]

If you have upfitter switches in your truck, they are already powered when your ignition is turned on. All you have to do for a light bar, is to run the power wire to the upfitter switch, and then ground the light bar to the frame. If you want to have the light bar come on with your high beams, then you have to use an additional relay as outlined in the video

[@joebeezy9471]

@@akgearhead this single comment and answer helped me more than 10 videos I just watched.

[@akgearhead]

@@joebeezy9471 heck yeah man! Great to hear!

[@TankHandy]

So if we’re using the upfitter we dnt need a relay. Got it so power from the light bar goes to the upfitter

[@akgearhead]

If you want the light bar to turn on and off using the upfitter switch only, yes. The upfitter switches already have individual relays for each switch behind your dash. If you want it to turn on and off with your factory high beam switch, you will need to use a relay in the configuration shown.

[@TankHandy]

@@akgearhead thank you. Btw you should do more how to’s. Good teacher

[@akgearhead]

Thanks man, really appreciate that! I definitely will, I just try to find ones that are actually useful for people, and that there aren’t already good videos of

[@user-hn6dd5re6o]

Where did you find the brackets to close in your gap for the mounting brackets? Just got a 24” bar and I’m dealing with the same issue of needing more surface to mount to than what I have between the frame. Thanks in advance.

[@akgearhead]

I just used some flat pieces of scrap steel and bolted them in place and then drilled holes to mount the actual light bar to them.
