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

[88-378]

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!!

The HVAC control vacuum line comes out of the passenger side of the fire wall and goes to the bottom port of the check valve located just above it on the firewall.

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!
