98 HVAC Vacuum Line HELP!!!

[tomvpr79]

Hey guys!
I am struggling with this vacuum line! There is a Tee splitter that is tied to the intake, Vacuum Reservoir and one runs into the cabin via the firewall. The issue I am having is, where does the line go that connect once it goes into the firewall? I know, just trace it, well mine is non existing (long story). I thought about running it to the HVAC harness, but I cannot figure out where to connect it to or what to disconnect and place it in.

Any Assistance will be appreciated!

If you want to just run a new line, there is a silicone connector on the back of the HVAC switch. There are 5 lines that run to this connector, the black one is the vacuum supply to the switch, that is the one you'll want to run the new line to.
