When first introduced in 2000, for a short period of time (6 months), they contained a small pcboard that was in the back end of the heater, that later was taken out of the heater. This part is no longer available and is not to be hooked up. If you need bypass instructions(for this circuit board), you will need to Email us for instructions. Also note that the high limit sensor 6600-168 is plugged into the bottom of the heater housing and connects to the Main Circuit Board. This part removes out of the old heater ("bullet" end slides into a drywell in the heater housing) and you install it into the new heater.
