Ok im swapping out the dash in my monte for one from an 86 GP. My question is which wiring harness will I have to use? Im not using the factory gauges or radio, just the heater and steering column controls. The extra harness I thought was good is all hacked up and so is the one in the monte now. I only ask because I know certain years change and im not sure what year or what car will work for mine. Thanks for any input!
