probably the brake booster vacuum line. find the brake master cylinder (where you put brake fluid). right behind it there will be a round thing that the master cylinder bolts into. there SHOULD be a a rubber hose about a half inch in diameter going into that round thing. if its not there, look around in the engine for a hose going to nothing. there should be a plastic elbow on the end of the hose too. plug the directly into the round brake booster.
