I am installing new brake controller and need to know what the wiring color code is on the 2005 Chev 2500HD. I have the factory "pigtail" under the dash which is now plugged into a Prodigy. The new controller simply has 4 wires which I need to splice into and need to know which color wire is the trailer brakes, stop lights, etc....
Any help appreciated !
