93 e36 325i wire harness [Archive] - Bimmerfest - BMW Forums Sep 22, 2006Hey guys, just got my 93 325i, and ive been doing the regular maintence stuff. Theres just a little problem with the stereo. The guy that had it before me, did a horrible job wiring it ( cutting up the wires ) and now theres hardly any room to work with and even if I want to connect the wires to an aftermarket harness, itll be a pain.
