I have a 98 and had a lot of trouble with the air suspension so I tapped into the airline just behind the drivers door wasn't easy took me a couple of tries to run anew line out with a valve right below the door and now if the rear is low I turn on the switch make sure all the doors are closed while running and in park I click it into 4 wheel drive and you will hear a bunch of clicks as all the relays open and I air it up with a compressor it's easy and quick if all the doors and other steps are taken than I turn the switch off and it's good for a while . No more bouncing. It works
