Ok I have tried a few ways to find this out. with no luck.

I need to know what the wires do (wiring pin out) on the XM module in my truck.

Truck is a 2004, GMC, Sierra 1500, has bose, with XM.

I know the conector is a 16 pin. and here are the colors and hole they are in, the rest are empty. but what are they. I need to know FOR SURE.

Pin 1 = Black with a gray stripe
Pin 2 = Black with a white stripe
Pin 8 = Orange
Pin 10 = Brown with a white stripe
Pin 11 = Dark Green with white stripe
Pin 15 = Green

any help would be awesome.
