Tinkering with crank position sensors

A good friend of mine Ash from Ashspec is helping make an ignition controller for my m120 v12 project so I can run carburetors and not have to adapt overly complicated systems.

This is me trying to figure out these sensors (and my multimeter lol lol)

If anyone knows where I can buy the opposite side harness pigtail for these 90’s Mercedes pins I’d love to have that info so I don’t have to junkyard crawl for them or lop them off and add my own.
