Where are they located?

What do I look for?

Does the pump coming on mean it is ok?

Thanks
Tried to find a picture of one but not luck. For my car, there's two (2) S/O valves located in the passenger highlight area. Have vacuum lines going in and out.

There's the main vacuum line going into the AIR pump and it's is notoriously knocked off!

The AIR working means it's 'ok' as far as I know.
