b18 intake mani questions

There are 2 things on the front of it. Both have vacuum lines to the intake piping. What are they, and can I just plug them?

If I remember right, I think they go to the charcoal canister(forgot what it's called).

I'll get some pics up tonight. Maybe seeing them will help
