Quick Vacuum?? Yes i have ALL Tmoss' diagrams!

I have all vacuum lines set except for where the line coming from "HVAC Controls" - labeled on the diagram from moss, that eventually tees into the vacuum check valve.

The mini tree on the passenger side can't be it as the firewall line and a/c canister goes to it (then off to the driver side main tree).

Am i missing something here?

Has anyone wrote notes on Tmoss' diagram indicating the locations of each?

I got the TAB, TAD, EGR Reg, reserves etc.. Just can't figure this one little thing out.

Thanks in advance for any help!!

I think i found my issue..
The two diagrams in the very useful page shows:
1. an '88 diagram and 2. a "typical diagram" for Foxes.

I will only use the '88. I was getting confused looking at them together!
