Working on wrapping up a bluetooth conversion using stock radio and removing Onstar. We are working on using the factory wiring for the call button and microphone. Does anyone have access to the wiring diagram specifically for the VCIM (onstar module) does not matter what year.

I checked the wiring diagrams posted on Schwartzy's site but oddly enough the pin out and full diagram is not there for onstar.
