89 190D Door lock wiring disintegrting

[nfokus]

Just bought a 1989 190D 2.5 (non-T), and was getting the door locks working, when one of the wiring harness connectors that plugs into the vacuum lock actuator crumbled to dust in my hand. It's a round, three pin plug, but I can't seem to find anything about it despite extensive forum and internet searching (with what must obviously be the wrong keywords)

I'd love to find a few replacement plugs with pigtails so I can continue the repair.

Thanks for any assistance!

If the wire insulation and terminals are good, insulate each terminal with tape / heat shrink tube. Pack the parts with terminal grease then plug together. To keep things from coming apart, make a splint with some tire wraps and something non conductive or fold the wires over on each other then tie wrap.
