Possible Pressurized air pump switch location

[Zombago]

Hello Winnebagurus,

This is my first post to these excellent forums, so please be gentle.
I just purchased an old '73 Brave D20, and am trying to figure out the possible locations for the switch to turn on the compressor for the old pressurized system. While I've opened the rear hatch I couldn't find any obvious switch on or near the air compressor, but it looks like it is wired up. I was curious if anyone knew the possible locations of the on/off switch for the air compressor. I'm hoping to get it pressurized, santized, and tested out in hopes this isn't a system I need to replace sooner than later.

Cheers,
Zombago

The ON/OFF switch for the compressor should be on the monitor panel mounted on a interior wall where you view the tank water level.

Most people end up converting to a modern on demand pump system because parts are no longer available for that system
