Default 98 t/a back side of intake manifold?

Hey guys sorry if it’s a stupid question but here it goes. I’m putting my car back together after sitting with a bent valve and apart for a couple years, I went with a FAST 102 intake and headers and a nick Williams throttle body etc. just some goodies. I’m putting everything back together, trying to make sure all my lines are in the right spot, all vacuum lines are connected and what not. On the back of the intake manifold, there are two nipples that come out, next to the map sensor, the big one goes to the brakes, the little one though... no idea, can’t find the hose to go on it, not sure where it goes to or what it’s part of, I’ve been searching for days, can anyone help me figure out what it is, what it looks like and where it goes?? Thank you very much

My best guess is its part of the AIR system? If you don't have that any more then I imagine plugging it is fine.

I bet it's for the HVAC system, which in many cars is vacuum controlled.

Winner winner chicken dinner...

It should go to the vacuum line that is loomed within the engine wire harness for the HVAC vacuum control.
