This is per a 1978 FJ40 but I believe the water temperature guage ratings (at least the sensor itself) didn't change through the years. Does anyone know the temperate-resistance curve (or even min/max) for the water temp. sensor and/or guage?

Thanks,
 
From hammerheads manual:
Sending Unit
60c(140f) = 90ohms approx.
80c(176f) = 50ohms app.
100c(212f) = 27ohms app.
105c(221f) = 23ohms app.
