I purchased a Metra harness kit from Best Buy and found myself with a huge problem! My 9C1 has the interior light kill button beside the radio, which shuts off the digital display and the lights from the head unit.
Enough background, now to the problem! With the OE AM/FM radio, the switch kills the lights to BOTH the radio and the display. With the NEW head unit installed, with the the interior lights switched on (get a display) it kills my head unit's power! So when I kill the headunit, the dash works. When i kill the dash, the headunit turns on.. uhmmm.. HOW?! Please LMK asap if you have any ideas or know which wire would be responsable for this..? TIA!!
