GM 30 Pin Wiring Harness

Does anyone have the schematics for the GM 30 Pin Harness that goes to the stock OEM radio? I've got an '08 Silverado with the Bose system (well, not anymore with all the aftermarket stuff I have in it now) and OnStar and was just curious if I could find out what each wire in the harness is used for.

OK, thanks. Their diagram doesn't appear to be 100% complete as I am trying to track down the wiring to the Bose amp under the center console. I am getting alternator whine when using OnStar and I think that although all my aftermarket audio is bypassing the Bose stuff and I have disconnected the OEM Bose tweets, I think the OnStar module still uses the Bose amp. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
