Default Mystery Vacuum Line....

I have one vacuum connection left mysteriouslly in my engine compartment, and one (of three) vacuum connections on my Super Ram Intake plenum available....The hose I have comes from the cylinder in the driverside front compartment, there is a y, one hose going to I believe the Cruise Control.... the hose that is left has a very small canister sort of thing that also acts as a Y and has two connections one of which is seperated by about 6 inches of vacuum line.... Anyone know what Im talking about? Im pretty sure the end of the hose goes to the intake plenum, but the connection with this small canister looking thing is a mystery to me....
Thoughts??
Thanx in advance
Paul

The small canister is a check valve. It sounds as if you're missing the connection to the A/C vacuum controller. Look for a line behind the distributor or just to the right of it (looking towards the passenger compartment). It's made out of plastic and passes through the firewall.

If it's the one with a little 90deg elbow, it could connect right behind the TB.
