You would have to reach out directly to your GMC dealership for a schematic for your car.

SOURCE: need to install my stereo in my car with out the harness for the stereo
It would be best just to buy a new wire harness for the stereo & the aftermarket harness for the vehicle. If you give me the year, make & model of the vehicle & the model # of the cd player I can get you a price on the two pieces you need.

Do not cut the wires from the car. Instead, call Crutchfield at 888-955-6000 and order the adapter part number 120701003. When you call them, ask for color coding. For JVC, refer to the attached picture. Match the adapter color code with that of JVC. If the adapter color code is the same, then connect ground (black), battery (yellow), and wire from ignition switch (red) securely. Turn on the car and see the radio works. If it works, connect one by one speakers and confirm. Remember, perfect connection gives reliable installation.
