I need a place to break down the wiring at each connector in my van. From what I know there can be up to four harness connectors plus antennas, usb, etc. I will edit this until it's done. Feel free to do the same with one post. State your year.

So Pins 1&9, 2&10 are the XM Satellite left and right channels. I have no idea of the voltages or the specs. Can these be directly input into an amplifier or?

Pins 7&15 are the mono output of the Onstar Cell... I assume anyways, or is this some form of digitized signal carrying more than just voice? If it is purely audio, is the signal able to be directly input into an amplifier? I just want to grasp the entire GM system.

Is everything controlled through the Low Speed GMLan wire? It would make sense to me if was, I just have no way of personally confirming this.
