Answer
Look along the firewall and you will see a thin black plastic tube going from the engine compartment thru the firewall and into the underdash on the passengers side. Back track this thin black plastic vacuum tube back towards the engine until you find the disconnected vacuum line in that connects to this thin black plastic line. Look real close as the vacuum line may be mixed in with the wiring harnesses that go thru the firewall.
