What Intake do you have? There is a Vac Port on just about every Intake Manifold out there. If you have the stock LQ4 Manifold out of a 2500HD then it wont have it cause the Brakes on the Truck are run by Hydroboost. You will have to add a 1/2" Vacuum barb on the drivers side..the spot where it would go has a factory plug in it.
