Stereo Wiring for Older Style 525i connectors?
Bought an aftermarket deck (KENWOOD KDC-155u) after the stock one stopped working. Did some research and read that replacement only required the Deck, Solder, and Wiring Harness. However, did a little more research and am pretty sure now that I have to connect each wire manually as I believe that the stereo wiring in my 525i is an older style that there is no harness for.
Would anyone be able to help me with the wiring from the KDC 155U to the BMW?
