vaccum line connects where?

[97dsmGST]

i just installed an injen intake pipe on. while i was removing the old stock one and removing the 3 lines connected to the intake, i realized there was a line that was not connected to anything, it was just hanging there. the line is coming from the same place that the line that connects to the bottom side of the intake is from. does anyone know where this line should connect to?

One line comes from the BCS (thinnnest line)
One line comes fromt he valve cover, and another line comes from some where in the back (i think it connects to some emmisions control thing..)

The third and largest vacuum line is from the charcoal canister, located under the battery.

The smallest vacuum line is indeed from the BCS. When installing a MBC, that line is usually removed and a rubber nipple cap placed over the intake nipple. The BCS is left in place, the electrical connector plugged in, with the nipples on the BCS capped off.

The second line is for the valve cover breather hose. Some people put a mini-filter on the valve cover nipple and let oil gunk spray all over their engine. Other people put a small inline fuel filter in the line and keep the line connected to the intake. Other people use catch-cans. Some people just leave the line plugged in.

And then you obviously have the BOV recirculation tube. That should be all the rubber pieces going into or coming out of the intake tube.
