door sensor and wire fried and need to be replaced

I have a GE Profile Microwave. A door sensor and the wire it is attached to is burned and needs to be replaced. I have the sensor, however, I need to find out how to get a wire to replace. It looks like the wires are only sold as a single harness (WB18X10460). The wire is yellow and black. Anyone know how I can just get this wire, as everything else looks fine.
