Isis Intake manifold help

So starting my SR build and the Isis intake manifold has me a little stuck. This is my first build so bare with me. I opened the manifold out of the box and noticed a big thread in the very end with no cap bolt or anything to go into, I also noticed there are more vacuum line nipples than what the stock manifold has. There are two extra sitting right below the TB. If anyone has used this intake and can shoot me some pointers or even pictures of theirs installed that would be great, thx guys!
