I have a problem with my wiring project. I've copied and printed all of what I thought I needed to know from this thread. I've pulled the stock stereo, unplugged the factory fader, and followed that back to a "Y" in the harness where the wiring goes back into the car and some of the other bends around and goes from the fader to the stereo.
I have a 88 325i with what I was told is premium sound. So far, in the harness, I've identified the RED/GRN wire as constant power, the VIOLET/GRY as switched power to ignition, the thickest BRN/BLK wire as ground, the thinner white wire as power antenna, and the thicker white wire coming out of the radio opening separate from everything else as the amp. I've also identified the YEL/RED wire as LF speaker POS, the BLU/RED wire as RF speaker POS, the YEL/BLK wire as LR speaker POS, and the BLU/BLK wire as RR speaker POS.
I've followed the wiring harness beyond this junction by hand all the way up and behind the gauge cluster and have not found or felt any other point where the wiring might split off or other wires might come into play. I only seem to have the four speaker wires I mentioned above. There is only one other wire left, which is a BRN/BLK that goes from the stock head unit to the fader. The speaker wires are not in twisted pairs, so how do the speakers ground?
Thanks.
