If there is enough wire extending from the connector, just solder some new wire. It probably would be a good idea to use some shrink tubing or liquid tape to protect the joint. If there isn't enough wire there to solder, you can get connectors with pigtail wires and just splice them in. The female connector w/wires is part number 15306156. The male connector is part number 154306166. Both are available from RockAuto (do a part number search). There may be more convenient sources, closer to you. This is a link to the harness assemblies, but I can't figure out which applies to you.

Note, If "push come to shove", and you need it done soon, just cut the connectors off and splice the wires together.
