As the connectors seem to be a nice molded part. For the throttle I would suggest just replacing the pigtail between your old Pie throttle and the new one.
But if this does not appeal to you or if you need several connectors, it seems that from previous posts it might help to contact the supplier directly at sales@goldenmotor.com. Perhaps they would be able to supply you with the needed female connectors.
Best regards,
