Disecting a GM Delco electronics factory radio to add a aux input. Here I have found pins 11- audio left 12- audio common 13- audio right 14- audio right on the top of the CDM box are unused other wise and are inputs. On the bottom of the CDM is the slave connector for the tape deck. Pins 16-14volts 13- Tape ON 11 Audio common 10-Audio right 9- Audio left are from the tape deck. Pins 16 and 13 shorted together jump the CDM into aux input mode as if there was a tape in the machine without engagement of the actual tape deck.
