Hi, Glen (and others), Thanks for the tips. I took the shell off this radio and determined that it's made in Italy, but learned little else. I'm pretty sure the black is ground, as it's commoned with the antenna-plug shielding. So that kills the DIN hypothesis. I've found there are a couple of US aftermarket standards that might apply, though they have striped tracers, and mine has none. Car radios often have a battery-hot wire (30) to maintain memory; an ignition-hot wire (54) to allow operation only with ignition switch on ACC or RUN; and an instrument-light wire (57a or 58) to illuminate at night. I'm assuming (!) this one has four + speaker wires and uses a - grounded speaker installation. So I'll begin careful testing.
The truth: I'm planning a concealed mount for the radio/cassette player where it can play a cassette I have of an hour of German police calls. I've tapped into the power switch in the old Telefunken FuG-7b Sprechfunkanlage, and also into its faceplate speaker plus an under-dash communications speaker. Right now I use a remote boom-box for the sound effects at shows, but that's pretty unsophisticated. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Glen Hadley Sent: Sunday, August 09, 2015 7:25 AM To: [email protected] Subject: Re: [vintagvw] VW radio wiring plug I don't know all of them, but the DIN standard makes the brown wire the power ground. In most systems, red is ignition hot and yellow is battery+, but I'm not certain this one would follow that convention, it could easily be reversed. Black is usually the speaker common. Beyond these guesses, I'm at a loss. glenh :<)>.
