I finally got a cd player for my 94 525i. I got the kenwood kdc-128 indash cd player. Does anyone know if this will work with my built in bmw amp? Also, the owners manuel for the car was stolen while the previous owner still had it. I dont have the schematics for wiring the new cd player. Can anybody please help me? I really need to get this thing in because I start school soon and Im running out of time. Do any of you have a diagram as to what each wire in the harness is for?
