I am in the middle of doing a H/C/I swap. I am going from a stock intake to a explorer intake. I have an 89 GT. My friend did work on the intake and had to leave. On the very back of the intake there is some sort of plug that looks like it had a hose on it but i don't know what it is. THe plug is plastic and has a little tube out the top of it. What is this, is it for a vaccum? Do i need to hook a hose on to it? Also the stock plug is larger than the hole on the back of the explorer so i can't reuse the stock one. Thanks nick

The vacuum lines you need are 1 small line for fuel pressure regulator, 1 small line for A/C,1 small line for EGR and another small line for the smog pump. One big line at the back goes to the vacuum tree for the power brake & A/C, one big line goes to the PVC valve. The other big line goes out the front for the carbon canister. In a pinch, one of the small lines can connect to the spare port on the vacuum tree. Cap or plug the remaining lines since they aren't needed.
