Theres a vacuum line on the harness, i plug that into the intake manifold. But there is another one coming out of the intake manifold.. From what jsteele90 said.. could that be for the air system which i no longer have?

so if i removed the air system, all i need to do is cap this off?

it's not the one for the HVAC system is it? make sure that is hooked up or turn on your heater or ac to see if it blows out the vents and not the default.
