thank you for the link....i have the onstar interface....i need the wiring diagram . i want to install onstar to a aftermarket radion....i don't have the bose system anymore. i have a amp installed to the door speakers
 
Check out Crutchfield.com - there's a module GMOS-04 that I had to buy to get my aftermarket radio to work with Onstar.  I believe JPCustoms sells this module as well.

If you have steering wheel controls, you will probably also need the SWI-JACK module if you want to keep these controls.  (I still need to buy mine...  it's tough without the steering wheel controls!!!)  JPCustoms sells these for less than Crutchfield, so I think I'm going to be making a purchase soon!
