Hello I just purchased a low mile 06 f250 reg cab xl its a 5.4 6speed 4x4. I was wondering if anyone could tell me if these trucks are prewired for the factory brake controller and up fitter switches? If so can I get the parts from a salvage truck? Do I need any extra harness? I do have forscan assuming id probably have to enable something but maybe its to old for that. My truck just has blank cubby on the dash currently. I would like to add that and factory cab lights if possible. Id appreciate any input thanks!
