The top one looks like a circular connector made by TE Connectivity.
That's what I'm trying to do, come up with a part number...
Just to prepare you though, it’s not at all unusual for OEMs to have custom molded connectors made that cannot be purchased outside of their own parts supply chain. It may be based on greed, but it also may be based upon very valid safety and/or liability issues.
Additionally, prepare yourself for the cost of the crimper you'll need to crimp the pins.
