Well my shaker is dimming, so obviously there is a wire going from the dimmer control into the HU.
When i try to follow the wire from the dimmer switch to the head unit it changes colors somewhere. There are 5 different wires behind the dimmer switch with different colors. None of the wires going into the HU has the same color as any of the wires coming from the switch. I find that kind of odd..
I am actually starting to wonder if my Shaker is factory installer or not. I bought the car used, so i have no clue. But i thought it was.
