Wire it in series with the compressor, clip it onto the tube running from the evaporator back to the compressor (not the one with the capillary tube). When the coil freezes up, the contacts open and stop the compressor. The contacts close again when the tube has warmed from thawing. You can tweak the operation by moving the thermostat to different points on the copper tubing...

Is this what you are using on your converted air conditioner to solve the frost problem?
