Can someone help me with where the wiring goes that are from the Aux switches 1,2,3,4 beside the brake controller on a 2005 SD 4x4 . I have been to two ford service shops. They don't know and its not on line on their FORD site. One service manger was going to e-mail after he talked to the hot line but that was several weeks ago. The wires come from the switches and goes into a wiring harness. Any help would be appreciated.
