I know absolutely NOTHING about the 1973 air ride system. So I know I'm LOST. Then with parts missing. There is a pressure shut off switch. Were is the manual off switch. The right side controls are not there. This part of this GMC is a mess. Bob Dunahugh

I pull the circuit breaker at the fuse block when I need to disable the compressor to do stuff.

I think when Jim Bounds has to restore the rear air suspension from mostly scratch, he installs what ends up being a PowerLevel system.
