Been pouring over manuals all morning and cant seem to find anything referencing this vacuum line and its connector, trying to find out where it goes so i can just be done with it and the hvac lines so someone please humor me and tell me where this thing belongs lol. its the two lines that run from the heat selector on the hvac control head

 

Looks like for the heater control control valve. (yeah I know that sounds stuuupid butt I don't know the right name, if there even is one) The valve on the control head that controls the heater control valve is separate from the main vacuum valve, because it's worked by the temp lever, not the "mode" selector. Those lines go to it.

 

Just saved my *** big time thanks man! For anyone in the future who may look at this post for an answer on exactly where it connects, it connects to a pretty oddly shaped black connector within the hvac control wiring harness (will attatch a pic below)
