I believe it’s a GX16-4 “aviation connector”,

EDIT: that’s if the outer diameter of that threaded part is approx. 14.6mm.

Just a little tip, buy the connectors with ceramic surrounding the pins/sockets.
The plastic ones are cheaper, but you risk melting them when soldering the leads if you are not that proficient with the soldering iron.

Thanks for the response, Thread is M20 and the cuts were slightly different

@nidershan I have the same set up and replaced my connector with the Aviation Connector linked below. Here’s what you need. Agree with @BrokenEndmill buy the connectors with ceramic surrounding the pins in you can.

Couple things to keep in mind when you wire your spindle. The spindle ships from factory with the ground wire (4th pin) not connected inside the spindle. You will have to fix the 4th pin in the spindle as depicted below.

Do not connect the shield to the pin 4th pin of the spindle plug. Pigtail grounds are known to induce EMI.
