Swapping back to stock intake ??

[wickedsvt2002]

I'm changing back to stock from the Boss intake.
There's a plastic nipple on the back of the stocker,
what connects to it? Am I missing something, I can't seem to find anything from my leftover parts

Thanks for any help

I don't see anything on the back of my stock intake manifold. Can you post a picture?

Pretty sure nothing connects to it.

Yeah, just checked with a light back there. No opening in it into the intake.
Thanks for the responses guys.
