Im working on replacing the head unit in a 93 325i. I purchased a universal wiring adapter and have connected everything up. The audio works fine when the stereo is in Tuner Mode, but if I try to use the cd player or the auxilary input I get no audio out of the speakers.

I have tested the back of the deck for audio and there is audio present on the output of the deck and throughout the universal adapter. So now Im at a loss for ideas, except to run all new wiring for all of the speakers directly from the new stereo. However, Im not quite ready to give up completely on the factory wiring.

I have found pinouts for the factory deck connector and the Amp connector. The universal adapter does seem to match the factory connector, but I am unable to locate the factory AMP. Can someone tell me where it is? I have also noticed the the color on the wires dont match, there is one color at the deck connector, but I cant find those colors at the speakers. Are there 2 connectors on the AMP? Does anyone have a wiring diagram for the audio system? Any and all info/feedback is welcome.

Thanks,
Jesse
