Does anyone have a schematic of the wiring of the 2002 Audi A4 Quattro 1.8T sound system?

What I specifically want to know is what wiresis going into what plug(pin) locations on the HeadUnit and the amp..

Also I want to clarify where the amp is located in the trunk.

Thanks in advance for all your help.

I have a few diagrams that may be helpful in my AudiWorld picture Poster:

I had a 2002 A4 without Bose...so I can tell you the amp is located in the trunk, right side, behind the side panels. Not sure where the Bose amp is.

Not necessarily. I think there may be a "Bose" name plate on the speaker grills.
