For the life of me I can't upload a photo to this site. Posting a link to a photo of my actual driver in my Google photo album if anyone would like to see what I'm talking about. Instead of the typical push terminals, this has a round connector with a threaded body. There is a large nut holding the connector to an aluminum plate that covers the area where the push terminals would normally be. From the looks of it, I would assume whatever cable connector is used with this would push in and then thread on to lock. Wild guess, but maybe it also has a rubber seal for moisture protection? This was purchased as a NOS part, and didn't come out of any cabinet.https://photos.app.goo.gl/JeX2fdjatRe1azUV6
