Need help with TPI vacuum lines near dizzy

Attached to the bracket which also mounts the remote coil, is a plastic molded piece with two vacuum lines and a 2 wire connector. The 2 vacuum ports lay fore & aft to the front of the car. Both came disconnected when I recently pulled the dizzy.

Which line goes where?

I think one line goes up under the plenum and to the T under the TB, maybe.

The other line might go to the EGR, maybe.

Can someone help me get these hooked up correctly? I know you are out there.

doc,
you are correct. the aft most one goes to the egr and the foremost goes to the "t" under the throttle body

Thank you.

There are so many tubes and wireing, that it is difficult to remember where they all go and should be routed.

no problem doc. i had to go out and look on mine myself. i'm hoping that someone might have an upper plenum they would be willing to part with. wanting to port one then install.
