After an unsuccessful attempt at swapping in a Symphony II (turns out the head unit I got was broken) I'm going to settle with a regular Symphony I. I've reversed all the wiring modifications I've done except for pin 4 of the 8-pin black connector. This is the switched power wire, named S-Contact and is supposed to be red according to ELSA. I remember pulling the pin out of the connector and taping it out of the way when doing the install but now I can't find the damn wire. Does this wire run with all the other wires for that connector or does it come from somewhere else? I've searched through all the harnesses behind the centre console and I just can't find where it is. Can someone help me out or take a picture of that connector?

I can't place the connection you're referring to just based on your description, but I'd be willing to pull my radio and take a picture for you if you think that would help?
