Steerable pusher axles will not track going backwards so are plumbed to raise with the trans going into reverse.
Many are plumbed to raise when parking brakes are on to put more weight on parking brake axles.
The regulator is mostly plumbed after the control valves that are controlled by the reverse light and the parking brake, and the dash switch may be hooked to one or the other as an over-ride to stop air exhaust during maneuvering in reverse.
