Update: I was removing the radio trim panel to paint it and ended up removing half my dash lol. So anyways here is what I found. The harness they used to adapt to the factory wiring only has one large plu and a smaller plug connected to a grey wire and small black terminal. Now where I am confused is there are three of the grey wires with black terminals and only one is connected. I am guessing these leads go to the factory amps. Is something wrong or is this normal?
