House circuits that I can think of on my coach, also a Liberty.

Generator air bags, air horns, driver's seat, bed lift, pocket doors, floor slide, and dump valves. There may be more items, but I think I got them all.

The chassis aux air system includes the air suspension (starting with the solenoid valves in the steer compartment, all Norgren valves and all air bags), the belt tensioner in the engine compartment, air shutters (if equipped), front door air lock, tag axle lift, and windshield wipers on some older coaches.
