Hello, the vacuum diagrams for a vehicle this old are not the greatest, but they should be good enough to getting your routing correct, give me 1 min and Ill post them here.

The 1st diagram is for your engine compartment components, and the 2nd is HVAC controls.
I will check for some additional diagrams as well.

Found one more for the Evap system, the Purge valve pulls vacuum from the intake manifold so it may have a hose if its not connected directly into the intake manifold.
