On my 05 there are two female plugs behind the plastic bin in the dash. One is for the brake controller, 4 wire, and there is another plug next to it, 7 wire. what is that for? Upfitter switches?
Yes...for approx $40 you can swap out the cubby hole for a set of upfitter switches and for approx $60 you can add the wiring harness that begins under the glove compartment and extends to the upfitter switches.
Its an option goes next to the trailer control where apparently we both have a cubbie hole. LOL I didnt know the parts were that cheap might have to get them also better than drillin in the dash.
