You'll find that many special plugs can be repaired/reused, there is a special tool avail. to remove connectors from the type of plastic plug they clip into.
(difficult to describe, but a common type has a one piece plug that the connectors are pushed into until they click in place from the rear after being attached to the wire. pushing the right tool into the front of the plug unlocks them for repair/replacement)
Cheers for not giving up, and figuring out how to repair that connector!
