I recently noticed that the engine in my 82 has a vacuum advance on the distributor with TWO vaccum connections.  It was bought new in TX, so I don't think it is a CA model (however maybe the engine was??? It is not the original, see > uknown engine #GD000861).  Long story short only the connection facing away from the distributor is connected (to the throttle body).  The connection facing the distributor is left open.  The book shows that a standard 82 only has one connection and a CA model has two connections, where the one facing the distributor connects AFTER the throttle body.  I don't seem to have a place to connect mine to.  Does anyone know why I have two connections and where the connection facing the distributor should go??

Thanks,
David
