You may be able to goto one of the electronics online order houses and order some "amp" or "amphenol" plastic multi pin connector and plug and the associated pins male and female and the proper crimping tool and just affix your own connector to this matter. These would be of a higher grade connector than some typical run of stuff. On the more immediate side of things... When is the last time you needed to disconnect this connector? Just solder the wires together with heat shrink tubing well insulating them and get on down the road.
