cant find my papers which told me to do this, but I eyeballed my '05/ prodigy setup:
truck contoller harness to prodigy harness
Blue to Blue
Black to White
red/black to Black
white/orange to Red
Hope it helps!
Mine had a direct plug in for my truck. Just plugged it in and drove on. You might check with Prodigy. Larry
dont use the factory harness ,buy the one from prodigy ,plug and play i have it less than a minute to hook up , keep it simply.
