Nanaboshi NJC-207-PF is the connector on the cable. Nanaboshi NJC-207-RM is the connector on the motor.

You can purchase this connector from various industrial equipment suppliers for much cheaper than what Yaesu sells it for. A few years ago I did a bulk order for more than 100 of these connectors. The connectors were about $8 each, but they did not come with the rubber boot. At the time Yaesu was asking $48 each, with the rubber boot.
