My truck has had the door replaced by the previous owner and it was replaced by a 2500 hd door on the front passenger. It doesn't come with a heated seat button on the door handle, I know there is supposed to be one because the passenger seat heats up with the factory remote start. So I have the door panel off and there is no harness for plugging into a heated seat switch. So I want to find out where the wiring harness for that switch starts from and have it ready for when I replace the door panel with the correct one. Thanks
