I'm begging anyone out there who has Step by Step instructions on how to do a deck swap. The issue arose when the stock wiring harness wires did not match the pin locations on appropriate after market harness. I can direct connect it but I cannot figure out if audi uses specific wire colors or its all random for its wiring. And If this exists please somebody tell me what all the wires in the stock Audi harness are for by color or guide me to a simple color diagram for this type of unit (this is the bose ceremony changer/tape deck) and how to in corperate the amp if anything needs done there. You would save my flippin life I installed plenty of stereos this is rediculous. As basic and step by step as anyone can do thanky you!
