Hey Gary:
Sorry that you've discovered that there clearly aren't many rocket scientists here that know jack about HVAC vacuum lines on these cars.
I myself am not a rocket scientist nor a amateur comedian honing my skills, but I helped another member out with this topic a while back, seen in this thread:

The system, at least on the engine side, is simple. The pod is your vacuum reservoir so that the system doesn't change modes under hard acceleration.
There are two ports on it. The larger of the two is the vacuum supply and should be connected to a port on the intake.
The smaller of the two is the vacuum signal into the car to operate the system. At the firewall, as you can see in my pictures, there SHOULD be a pair of vacuum lines. If you have only one, then one is missing.
One is the previously mentioned vacuum source leading to the control inside. The other COMES from the control and operates the heater valve located in the heater hose.
Speaking of which, if that's one of the originals which has the external lever on it, forget using it. They are no longer made and you can't fix them. What you CAN do is buy a new replacement but it's VERY important that you do some research to determine if the valve is OFF with vacuum applied, or ON with vacuum applied, then buy as appropriate.
Kudo's for getting the AC going. However, that's where you screwed up. If you had asked for advice on how to REMOVE the air conditioning system and throw it away so you could sweat your balls off in a car that DID have AC, then you likely would have received several serious, detailed replies.
The system is still intact on my car so if you need help finding out what may be missing, let me know. You can PM me about if you don't wish to deal with the peanut gallery.
