I didn't have time to swap hose positions on TTV, nor remove/test it, but I did remove the heater blower to allow greater visual inspection of the plumbing.

If it's supposed to look like this...



... it doesn't.

As previously discussed, the vacuum hose from my WUR goes to the middle port of the TTV. The hose from the side port of the TTV then goes to a "T" fitted on to the Vacuum Limiter. The hose on the other side of the "T" goes into the throttle body(?) on the back side (not the front side as in the schematic).



Here's the port (circled) that the split from the TTV is supposed to go into per schematic



Here's a vid:

Does anyone have photos of a dropped '79 USA engine showing CIS intact?

Thanks,
Jason
