Unfortunately I don't have a digi cam or else there would be pics to clarify. I have a 92 ls motor and on the throttle body (above the mechanism that rotates and the tb cable slides through) there is a piece that connects to the tb, and it sits higher than the tb. This piece is circular and has a flat spot which is the size and shape of a silver dollar. There is a vacuum line that runs off of it to the oem intake arm from the factory. My intake charge pipe doesn't have a fitting for it. Is it neccesary to run this line or should I plug it at the tb? Btw, I'm not referring to the vacuum line that routes to the evap canister. I sifted through the ls turbo thread but it appears that the newer ls motors don't have this piece attached to the tb.

Here's a pic of what I'm talking about:


Should I tap the intake piping for the vacuum line or just plug it?

Okay, so should I plug the fitting, or leave it unplugged with the vacuum line unhooked?

Take the valve off your intake manifold completely
