Default Intake Manifold

Can you help me out ?
I took a look at the center intake manifold/plenum
ontop of the engine.

On the back of it , facing the firewall , there is a small
black nipple or tube sticking out without anything going
to it ? It's the one located above everything else.
Is there some vacuum tube that is supposed to go there ?

I had my rear main seal replaced a while ago and maybe they left something off , The only thing I can think of is that its for
TRAC control which I don not have.
