****1987RX7guy******

I thought he was wrong too, but I looked in a 91FSN and sure enough on those models they have both sensors on the back side of the water pump housing. My 87's have it like yours. Water thermo on the back sided and the water temp(fan)switch on top. Ref page E-14 of the 91 FSM.

Thanks HAILERS

Crusader_9x-It appears there are more than one on your on the back side. In any case use the green one with two pins.
