What is this supposed to connect to.

I don't know what this vacuum port is supposed to connect to. The old TB that I pulled off it didn't have this port. I can't tell for sure from some the diagrams Ive been looking at. Its just in front of the port the T's off the vacuum canister and the EGR. Thank You

Re: What is this supposed to connect to.

The hard line you have thats open goes to the Tbody where the rubber vac line is now. the hard line is missing its 90deg elbow that connects the 2 which is prolly y someone just ran a new line..

That probably is the supply to the EGR solenoid. It should be connected to primary vacuum.
