I put the harness all together with the panasonic head unit tonight that has pre-out rear and fronts on the head unit and plugged in the harness and the stereo wont turn on. Is there a signal wire i'm missing to turn this thing on or what. I believe its a METRA harness. 2002 Audi A4 Quattro. its not the 25 pin harness either...2 separate harnesses, one for power and such and the other is for speaker connections...please help ASAP...
Mike
