Welcome to the forum.
What year and model vehicle are we talking about?
Do you mean the BPT valve near the EGR valve?

Take a look at the ESM here: http://www.nicoclub.com/FSM/Hardbody/d21_truck_1989.pdf
Pages EF&EC-9, and EF&EC-158 to161 detail the system.
If you need the underhood diagram let me know. It will take a bit more time.

Here is the underhood label.
I think its a bit easier to understand.

Good. Its from an 87 but I don't think there are any differences.

Here's this one specifically for an 89. I used it this morning to correct some mixed up hoses causing an irratic idle. Let me know if it helped.

What lines go to the five exit vaccum port on the air cleaner?

The center port on the air cleaner tube group goes back to the intake vacuum port.
That then branches to the 2 solenoids.

Mine only has for 4 hoses, I bypassed it tho and ran them directly to where they go.
