I should add that the wires for the AUX button already in the truck are behind the passenger side kick panel. The instructions are hard to find. I have them (mostly readable) for the power distribution box (Accessory Wiring Junction Block Package – Part Number 84938257) and the accessory with another 3 AUX switches (part number 84938261 – mostly readable). I can post them here if somebody will tell me how to do it.
