Weisbaden with Sony/Blau/Audi CD changer question

[Huw Powell]

Hmmm, ok, but this radio/cassette only has stock plugs in the back - 
three rectangular ones and the two antennae.

I don't think there are any "changer" wires, except for the lovely 
scotch-loks used to tell it to turn on.  It has a separate wired remote 
controller velcroed to the console next to the e-brake.

Keep in mind this was 1988...
