W126-W123 door lock conversion
 

Time to re-do all my door lock actuators. Every single one leaks slightly creating a large total leak. I would like to run a full W126 electro-vac system with the actuators and pump.
Does anyone have an electrical diagram and vacuum diagram for a W126 door locks? I want to know what I am getting into as far as running lines.

simplier idea may be to go with 12v door locks? Solinoid and Mechanisims for this I think are in JC Whitney. Think it is they who sells retrofit kits from manual door locks to 12v.

You'll also need W126 door and trunk locks with central locking switches. You'll need power and ground to the switches and one wire from each switch to the pump. The plumbing is easy - one line to each actuator.

You have to decide what year W126 system to use. Early W126s (through 84?) don't activate central locking from the passenger side or trunk. At least that's how I remember it. Later W126s have a second set of lock switches for the security system.

Hey, I have the wiring diagram if you still need it.

Unfortunatly I am now headed to St. Augustine Florida for vacation.

Mike has it on the w126 CD... If you want to get it from him.

The earlier system is fine. I looked at the retrofit kits and most seem really cheap. The W126 system would still kinda be OEM and I don't mind running the extra wires.
