I installed the universal in my car. As I recall there were two wires of one color (white?) and one of antoher color (black?) The two same-color wires are for the heating circuit. Splice them to the two same-color wires in your harness, then splice the other one, and you're good to go. I covered each individual splice with heat shrink tubing, and then I covered all of them with a larger piece of heat shrink. It works just fine, and much less expensive than the OEM sensor.
