Wanted: Tesla M3 Battery Rear Drive Unit Connector

I'm looking to source the connector on a Tesla Model 3 battery that is used to connect to the rear drive unit. This is to allow me to power a rear drive unit using the stock Tesla HV motor cable.

Hoping that someone re-using an M3 battery/PCS might have one going spare.

Unfortunately I can't find any good pictures of the part anywhere. Does it have bus-bars that it would be possible to attach to? Wiring harness for the HVIL pins?

Yes! Thanks for digging those pictures out. That's exactly the right part. It looks unboltable.

I looked at buying new parts from Mouser but it needs ultrasonic welding onto the tabs and the pins for the HVIL are MOQ 20,000.

I think you can install it in a plastic housing. The connections are the two M8 screws. The small screws are integrated in the carrier that holds everything together. You can saw out the corresponding piece. There are two of them, for the front and rear. I only had one fitted.
The pictures are of the parts I have lying around.
