I have the Recaro. Parts search did not go well.

Here is what I did:
Using one additional toggle switch and repurposing one existing switch I have a kind of manual control that I like.
I installed a small air pressure regulator, adjustable with my left hand while driving. That allows me to have exactly the pressure needed to counter my weight on the bladder. Each year is just have to slightly increase the pressure :-)
The toggle switch controls a solenoid that turns the air on and off to the bladder. The repurposed rocker switch exhausts the air from the bladder.
Yes, the seat rises when I get out of it. When I get back, I press the exhaust switch and I drop down and am ready to ride.
