Default Missing Vacuum Line

I installed a K&N in my "new to me" 95 SE, and noticed a hole on the backside of the intake hose at the airbox. Is there suposed to be a vacuum line there, or a plug?

Looking around and under the air box I did not see any "loose" vacuum lines.

Thanks,
Wendy

That sounds like the Intake Air Temperture (iat) sensor hole. Is there a small plug (about an inch) with a wire hanging around there somewhere? Push it back into the hole if there is.

Found it wrapped around a wiring harness, hiding the plug under everything!

Thanks!
