Trying to get this 92 Z28 a little more sorted out. I believe the AC compressor and system is full of frreon but have no verified YET. The compressor is not cycling on so I need to see if the cutoff switch is bad.
1. Does anyone know which relay on the firewall is the AC compressor relay?
2. Is this vacuum routing correct? I replaced the vacuum to the vacuum ball and now I get air through vents. I think this is correct anyway. Not sure if I need this fat one-way valve or this black/clear one at the intake or if it matters.
Re: Do I have this cruise control routing correct?

#1, your car does not have a relay for the A/C compressor clutch, that was a six cylinder car thing only.
#2, yes, your vacuum hose routing looks like it's supposed to.
As long as that new valve functions (one way) like the original, I see no reason why you couldn't use it
