I just got the 2001 LQ4 motor in and Im running Ls3 heads with 2008 6.0 Vmax intake in my 2001 Silverado.

My question is that my brake booster vacuum line has no where to plug into on the new 2008 intake.

My old intake hose came right off the back of the intake and on the 2008 intake it has a plug in the same spot but its not set up for a hose. It doesn't look like this plug comes out. Where do I plug this in now for my brake booster?

 

Does the rear of the 2008 manifold look like this?

 

Yeas it does, I figured it out as there is a plug in it and Had to go to junk yard to get another plug that had the end for the hose.
