Hi Ron, how've you been? Hope all is well.

Agreed with the comments that one switch should control both fans. The switches below are chosen based on the premise that they shall be located in the radiator's inlet tank (the lower tank) so as to sense the coolant temperature regulated by the thermostat. They should give you fans which cycle on when needed & off when not needed, instead of being on all the time.

Manufacturer...Part Number.........Switch Setting........Thermostat
Intermotor........50190......................100°/95° ...............195°F (91°C)
Intermotor........50104.......................97°/92° .................192°F (89°C)
Intermotor........50200.......................92°/87° .................180°F (82°C)
Wahler...............823.959.481.F ........92°/87° .................180°F (82°C)
