Were can I find some instructions on how to hook up something to the upfitter switches - like some reverse lights like rollingrock is talkin' about. I'm also looking into doing the same to some front off road lights...Please advise if possible....
If you already have the upfitter switches installed, you can hook up the items to the four wires that ar under the hood by the left hood hinge. There are three circuits that are 20 amps and one that is 30 amps. The four wires under the hood are the "HOT" wires for each switch.
I have the same truck with the 4 aux switches next to the trailer brake controller, but i cannot find the wires you are talking about. are they just hanging out or what?
