Thanks, but that is not what I asked for. I have this diagram, it is for the radio connector. What I want is the round CD Changer socket that's below and to the right. If I know which wires are audio inputs I can construct a box that will splice in there. With one of those clever guitar amp 1/4" stereo sockets I can make the CD audio to be disconnected when the external device is plugged in. I believe this is possible for our radios. The thread you pointedme to talks about the newer HU head units (2001 and newer?) that use the digital stream between the CD changer and the head unit. I do not believe this is the case with our cars from the previous century. I believe the audio signal that comes from the CD changer is analog and feeds into the pre-amp section of the head unit whereby it gets affected by the volume and tone controls. What I am plotting is to splice into the CD changer auidio output with my clever socket and REPLACE the CD changer signal with the signal of whatever I plug inito the spliced wire. The head unit will still think it's playing the CD changer audio. I just need the wiring diagram of either the Alpine CHM-620's cable or the Volvo head unit's CD changer socket. If, however I am wrong in my assumption that the audio output of the CD changer is analog, all bets are off.
