Electrical Removed smog-vacuum line question

I need to look back at my car, but the EGR lines are separate from those lines, which are for the TAD and TAB controlling the air pump bypass and diverter solenoids.

Basically, for the EGR, you have a single line that comes off the vaccum tree on the manifold and goes over to the pass tower area to the EGR regulator, and then a return line that connects to the EGR. I need to check to see if there is a check valve. You can use soft vac line here if you want, or dorman sells replacement hard tubing.

The TAD and TAB can just be unplugged and removed and the vac lines capped as far back as you can trace them. There will be two codes stores, but they do not affect how the engine runs or trip the CEL

Just also be mindful there is an HVAC line that runs to the same general area. It comes off the vaccuum tree of the A/C port and runs over to the pass side. It goes through a check valve and a tee and one line goes into the firewall to "power" the dash vents, and the other line goes into the pass side fender to a vacuum canister. The canister is to hold reserve vacuum so your vents stay in the position when you go WOT.
