My 1986 doesn't have one. Figure out if it's normally open or normally closed (measure the resistance across the connected terminals, having first disconnected them). If it's normally open, then just disconnect the terminals, secure them with a cable tie, and forget about them. If it's normally closed, then disconnect them and connect the two terminals together securely. As for it's vac connection, just plug it off. -- Grunff
