I did mine years ago but I don't remember one coming out of the MANIFOLD to the air cleaner. There is one coming from the TBI that you simply plug. Maybe I am wrong but I am pretty sure that there is none from the manifold.

It is a vacuum hose that goes from the drivers side manifold to the snorkel on the stock aircleaner.....i think it pumps exhaust back throught the intake????

If that is what you are referring to that is what heats the base of the throttle body so it can operate properly in cold temperatures. I just disregarded mine and plugged the vaccuum line up. Some say that it can cause problems when it gets cold and your car runs funny but in 3 years here in Ohio where it gets to sometimes 5 or 10 degrees on a warm day in winter, I have had no problems.

A vacuum port plug..

Most of our more ghetto-rigging inclined people just use a vacuum line with a screw in it though (yuck).

Ghetto rigged with a screw here, and I claim to be nothing else

You should see my exhaust! 3" to the 2.25 y-pipe is the most ghetto rigged thing ever!

Ain't nuttin' wrong with the screw in the end of the vacuum hose. I ran mine like that for multiple years. You can't even see it unless you pull the air cleaner off.
