Yeah - I was just checking a few of my Bentley manuals for the 5000 and 200
as I don't have one for the 90.  Apparently the information I gave earlier
is WRONG!  A big ASSU&ME!

Audi did a lot of interesting things with these steros - integrating
multiple amps antennas ans taking control feeds from the tach and trans,
etc.  So my interpretation of the wiring at first glance seems to be way
off.

The diagram for the Wiesbaden is in the 200 series manual and shows the
red/top connector for the rear speaker connections.  Since only 3 wires, I
presume that the brown is common speaker ground to an amp and the other 2
are left and right +.  I guessed the middle 8 pin Brown connector is for
front speakers correctly. The bottom Black 8 pin is for power feeds.
Diagrams shows whit for antennae powering and really need a proper diagram
for the specific car to get this stuff right.

Anyone have a good diagram of the radio connections for Coupe Quattro?

Ben

I tested the red plug last night and it's not powered so must feed
something, i don't know if the rear speakers are amped or not i have yet to
take them, if they there is no difference in their lousy performance with
not using this plug.

i think the plain white wires are for powered aerial, red and brown stripe
is a continuous power supply, brown is an earth,

As for speaker wiring i have never been able to work what goes where on
these cars, and have in the past just rewired all the speakers with decent
cable rather than the thin crappy audi stuff, ditto the power supply and
earth.
