Anyone have access to the vacuum hose diagram for 1979 Malibu with Air Conditioning? What I need is from the intake source to the ball canister to the heater vent controls.

The intake source is simply manifold vacuum. There is a special fitting with a check valve that keeps vacuum in the ball and heater during low engine vacuum such as WOT. The fitting looks like this:
The RH port goes to the manifold fitting, the LH port goes to the HVAC, and the center port goes to the vacuum storage ball.
