IF you plan to do the work yourself be sure the leveling jacks are down when you start working on the air side of things; just in case you dump any air the coach won't set down on you. The tap must be on the service side of the brakes so some one will need to push the brake pedal for you to verify the right side of the manifold to tap into the port. Let us know if we can be of any further assistance.
