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.
