To make it short i am swapping out my stock audi delta radio with an after market cd player. The a4 is a 97 no bose or stock amplifier to my knowledge. I wired up the harnesses and found the rear speakers not to work. I noticed the second harness that plugs into the cd changer is made up of 3 multi- colored clips that go into the harness. I noticed that one of these plugs may be responsible for the rear speakers. The aftermarket harness does not fit the stock cd changer harness. I looked on ebay and didnt find anything siilar to my car 2nd harness. If you have anyclue about what im talking about please help me out.

 

hey bro, you might need this harness...search google for the best price use the harness part number

thanks for bein the only one to respond lol.. anyway im pretty sure the harness w the red is for a4's equipped w Bose. My A4 is early b5 w Delta and a 6 cd changer. I already bought a harness one plugs in but the harness for the cd changer does not fit. The harness for the cd changer has something to do w the rear speakers thats what i found when i disconnected the cd changer harness from the stock radio.. the back speakers no longer worked.. confusing i know
