Ok guys as stated I have onstar and Bose just trying to make sure I have the right harness. I have the gmos-01 have the feeling it the wrong one if soo will it work.
unfortunately, you have the wrong harness...
to reatin your RAP's, OnStar, and BOSE, you need the GMOS-04.. using the GMOS-01 will net you no sound.. you would need to run speaker wire from each door and find a way to power the BOSE amp.. just return the GMOS-01 and get the GMOS-04 if you're wanting to retain everything
