Vacuum lines help

Hey everyone, got my engine running but it is running really rough. The engine is a 1980 L28 with a p82 intake manifold. So I'm trying to hook up all the vacuum lines and make sure they are in the right spot.

Here is the ac vacuum tank.

Heres the ASCD servo valve, not sure what connects to the purple arrow.

I have a vacuum line coming out from the fire wall but im not sure where it goes.

This valve is on the intake next to the hose that hooks up to the charcoal canister.

Lastly, what hooks up to this fitting on the bottom?

Well, there's a few extra things on the turbo intake, but the basic parts and vacuum stuff is generally the same on all of them. The little valve on your last picture is for the A/C system. It increases the idle speed if the A/C is running. The missing line should go to your Idle Air Controller...

Thanks again I found out that I had the fuel pressure regulators vacuum hose hooked to the wrong area. So I hooked it up to the fitting in the 4th picture with the orange arrow. So is the idle air controller conected right after the air regulator?
