It is the same as for the slides, although I would always just jump for some power first. The problem is which valve controls which bed, the factory didn't seem to have that info for us late owners. I think that 2 beds are controlled by the valves in the compartment behind the RF wheel and the other 2 are controlled by a set of valves under the floor in one of the smart bed bays. I plan to make a diagram of mine when I get a chance and will post it if no one else does it first.
