I have found both of mine. (Outside and tankage). The outside one is behind the drivers headlight and the tankage one is in the water bay to the right side. Both are connected with White and black wire pairs. Of course your mileage may vary.

I had presumed that the sensor behind the drivers headlight was for the dash mounted temperature gauge. My bay gauge is in the water bay on the drivers side as my temperature gauge is on the drivers side of the coach in the kitchen.
