Tom, I would go to the compressor itself and see what power leads you have going to it. Identify the hot (+) wire and see what is printed on it. Then go back to the controller and see if you can locate it there. That is the wire I would add the switch to.
Keep in mind though, the Air Ride electrical system has several interface systems also, i.e. the vehicle won't squat in certain conditions such as open doors or compartments, or if you have an O2 cylinder lift and it is deployed in the down position. These conditions won't stop the air compressor from running, but low or no air may affect other things or give you warning lights/buzzers. But in that case, all you would have to do is flip the switch and restore power to the compressor to see if that corrects the problem.
