Alright, I have this new head unit already that part is done haha. Do you know the part numbers that would be needed? I found a wire harness with part # 240112B00 but I'm not sure if that's it. Would the BCM need to be switched also? If all of that is needed just for heated seats i'll probably sit out on that for now but I would at least like to know what the part number is for the main harness for the steering controlsIt isn't one harness. For the seats it's three, Main, Body, and Engine Room. For the steering controls it's just Main, but you'll need a different head unit and possibly a new spiral cable. Be advised that the console and dashpad both need to be removed to replace the Main Harness. It isn't a small job.
