I have two vacuum lines that aren't hooked up, where do they go? one comes out from under the rear side of the upper intake, can't see under it but it is a metal line thats blocked with a piece of rubber right now, the other line comes from the front side of the charcoal box, it is a small hose that is tied in with a two wire hook up, I think the hook up goes in to the last plug on the left side injector harness. I have pics but can't get them to come up.
