I don't know if the connector is still available, look through PartsShop and FastLane they might have it. Might also try the dealer.

Now for the locks. The passenger front tries to lock but wont go. Sounds to me like the upper diaphram for that door is shot - probably has a hole worn in it from the passenger window making contact with the actuator. The rear doors probably aren't going to lock, or even try to lock, until the front passenger lock is vacuum tight. There really isn't anything you can grease to free up the rear locks, the only "moving" part to the system besides the actuator is a small, spring loaded link that allows the locks to be operated no matter what position the actuator is in.

If you find the front passneger upper diaphram in the condidtion I described, you will most likely want to replace/repair both of the rears too. When I did mine it was suggested I do al, I only did the two that were bad and 6 months later the locks stopped working. Had to go through the entire troubleshooting sequence to find the one door I didn't do was the problem.

The diaphrams for the actuators, while on the inside of the door, are still external and exposed to the weather and elements. The upper diaphrams tend to wear out first as a result. Even the slightest pin hole leak will bleed off the vacuum quickly. You can tee a vacuum gauge in the line and run the engine to build vacuum, shut down and time how long vacuum remains. If the system is tight it should hold all night without problem. More than likely you'll see vacuum fall off to zero in minutes if not seconds if tested today.

While doing your trouble shooting, be sure to disconnect the leg going to the resevoir and be sure to plug that line. removing the resevoir from the equation will allow even the smallest of leaks to be easily observed.

There are 3 or 4 (can't recall off the top of my head) connectors to the master valve. Be sure to replace all to eleminate them from the situation. Rarely do the master valves go bad, but they can.

For the straight connector, simply use apprpriate size vacuum line from the local Pep Boy's/AutoZone and use about 2 inches per onnection.
