I need the pinout diagram for the GM 9 pin auxillary cable.  It is currently connected to the OEM head unit going to an external tape deck.  I am installing a DVD palyer and would love to use the existing wiring.

Thanks

The pink is the radio on circuit. The gray is dash lamp circuit. The bare wire is a drain wire for the audio harness. The GREEN / WHITE is the right channel + audio signal. The BROWN / white is the left channel + audio signal. The BLACK/ white is the audio common. The black is power ground. The green is a data line for the various audio and Onstar components. The orange is battery. The audio line won't work unless the correct data message is sent along the data line into the radio.
