You're probably going to have to purchase a tail with the connector and splice the wires. I would get some heat shrink tubing, some splicers (the tubular ones, not the cones) and crimp the wires into place.
First slide the heat shrink over the wire harness that's large enough for the 2 wires and splices. Using a crimping tool, splice the wires, and then slide the heat shrink into place and shrink it.
I may be wrong, but I don't think you're going to find any other inexpensive way.
