258 TAC vacuum line routing

So I went to smog my Jeep today and I failed here in CA due to the fact that I have one vacuum line missing. it is one of the ports on the bottom side of the Air cleaner. There are 2 ports one is hooked up to the TAC unit on the inlet of the air cleaner. The other i do not know where it goes. I believe these ports on the bottom of the air cleaner to be the second thermal switch. Can anyone please help me out on this one. I would like to get back down and get this thing to pass smog today.

Thanks for everything

Chris

That is exactly what I am looking for but where does the line on the right go to?

Are to talking about the line labeled "manifold vac source"?

If so, that line Ts into the TAC line, then connects to a manifold vacuum port either on your carb, or the intake manifold.
