This heater includes 2 sensors with new style 4-pin sensor plugs (2002+) and an auto-reset high limit as well as a built in pressure switch with cable, sensor adapters and tubing to help connect drain line if needed.

This universal replacement heater contains a pressure switch which is not used on all Watkins models. If your heater has a gray wire coming out of the back or side of it with a small white connector that plugs to your circuit board, then you have a pressure switch.
