I replaces the factory receiver and cd player a long time ago (7+ years) Ive have been having an issue with loosing a speaker so I took the radio and some of the plastic out to see what I can make of it. I remember using a schoch harness. There are a bunch of orange wires that it seem I cut and taped off. Now I dont know what they go to! I found one wire that I apparently had crimped. It had pulled loose so I reattached it. In any case I messed something up cause when I put it together I get power to the tuner (*display works) but no sound. That is my weekend cars I just put it on a back burner but if anyone can give me some diagrams or pointers it would help a lot.
