Hi everyone,
I am trying to get wiring diagrams for the Bose headunit and the harness to the BCM, as I am trying to test the connection between the BCM and headunit for low speed GMLAN.
Have found couple of diagrams for same plug but not same pinout.
I tried to connect professional diagnosing tools and also dealership told me the headunit not reading on the tool and they think there is issue between the connection.
Any help with the diagrams or manuals?
