Could anyone tell me exactly what pin this wire in? I did an Install several months ago, and my customer got a new car. The dealer uninstalled everything and didn't give her back the RCA connector 1, so I can't use the circuit to bypass. I was going to try and just solder a small wire to that pin, if its possible, but don't know which pin it is. Let me know if you think it would work.

I really dont know what you are asking.

There is a blue/white on connector 1 that is the remote amp control wire.

Are you trying to find and unused pin to pull and move over for the bypass?

couldn't you just order one from pioneer?
