I don't have a wiring diagram of anything under the hood so I don't know if it is already wired and I just have to find the wiring and plug in? If I decide to get a wiring harness, are there multiple types and if so which is best? I would like to go to the upfitters, I have no idea how to get there from the fog lights?
I have looked up harnesses and have found multiple options but I am really not sure what route I should go. If anyone has done this, please share info. I appreciate any advise.
just run the hot up to the firewall that is right on the driver side close to the top, and there is a bundle of blunt cut wires, these are pass through wires, all they do is get you throught the firewall under the dash by the parking brake , once you get in there connect the correct color pass through wire you spliced into under the hood the the correct color upfitter switch wire you wish to use which there is another bundle of wires that are capped with a black heat shrink on the ends under the steering wheel, if you open your owners manual there is a page that tells you what color wire is for what upfitter switch.
