What attaches to this? Throttle body.

Ok so I took my throttle body off to clean it up because it was idling really rough. I noticed that nothing was attached to the little knob that I am pointing at below. I assume that is a vacuum knob of some sort. The problem is I can't find any tubes lying around that should attach to it. Anyone know what goes on that and where I should look for it?

I don't see any unused lines coming off the manifold. Do you know where it is on the manifold?

I'm seeing other threads where they say it should be capped on a 2.5L so unless someone else says otherwise I'll cap it.

That may be the reason it's idling rough.

My 1995 had it capped off, my earlier 1991 did not have the port on the TB at all.
