I have a 1992 XJ. There are three vacuum lines on the back up the intake manifold in a row behind the throttle body, and one on the base of the throttle body itself. I read where the (now missing line) coming off the throttle body goes to the MAP sensor. One of the connections on the manifold goes to the CCV, and one to the brake booster. Where would the third connection go? I am assuming to the passengers side where it goes to a connector to the cruise and the canister?
