You're probably referring to my post about radio illumination for the
4000 and coupe series.  Pin 3 of the connector provides radio
illumination, but that comment refers *only* to the Audi Rothenburg
radio setup.  I don't know what radio you're running in the Quantum Syncro,
so it may not apply.  Anyway, on the Audi type 81/85 the radio illumination
lead goes to the cigarette lighter plug illumination ring, and is daisy
chained to a number of other dash illumination components, all in the same
circuit downstream from the illumination dimmer rheostat.  On the Quantum
YMMV.  You should look at the wiring diagram in the appropriate Bentley
manual.
