13-Pin DIN CD Changer Cable

Here are the pin-outs from the Audi OEM cable to the H/U.

This is a view looking at the female socket.

Pin 11 = CH-DATA

Pin 9 = CH CLK

Pin 13 = R-DATA

On the diagram here, the L- and R- should be reversed. It's no big deal, as the are common grounded together anyway.

BTW-pins 6, 18 and 12 are not used.
