Hi: For some reason I can't post to the Audi newsroup so I thought I would try it here. I recently was given an 86 audi 5000. I'm trying to install a new stereo (with a CD). The wiring has me a little confused. I've managed to figure out all of the speakers and the hot wire (connected to the read defroster--go figure), but can't figure out severl wires and/or get the unit to power up.
Specifically, does anyone know which wire would be the ground (there is a black wire off the old unit in the harness, but it connects to a brown lead).
Also, there is a yellow wire that runs into a small black box that contains a fuse and a small transformer. Does anyone know what this is? Is it a wire to keep juice flowing to keep the station-memory powered up?
There are alos a few other wires and a "U" shapped plug?
anyone have any idea or thoughts where I could find a wiring diagram with color coded explanations?
I have the Chiltons for the 86 but is no help.
Thanks Mike
