The vac line runs from one of the ports on the plenum (rear RHS ) to a one way valve by dist.
Rear port of valve joins to a plastic line( very brittle and easily broken ) that is in the wiring harness on firewall and goes inside to HVAC controls.
Side port has a rubber line T'ing off to cruise control and continues along wheel well to vac ball under drv side headlight.

You can see the vac line in this pic, ignore the circled part.
Center of firewall, behind the pink dist wire.
Connects to Tee in Rod's pic.

I checked the hose at the circular tank and I have suction and I check at cruise and I have suction, but my cruise doesn't work and neither does the a/c door. I'm so confused. Sorry for my lack of intelligence. I'm 16.
