This electrical retrofit is designed to replace the traditional electromechanical thermostat, as the thermostat when used in that model year was prone to failure. This retrofit kit uses an electronic circuit like the newer models do to regulate your temperature. The proper thermistor is included, so if you need to replace your thermostat, this should be all you need.
