Here you go....not the exact part number but this guy has the right ones and they work. I have done 3 conversions.

Red wire to battery, black to grounds, plug the male connectors into the old headlight sockets then plug the headlights into the new ceramic sockets. Everything else remains the same.

Done in 20 minutes.
