Easy to install and adjust! This is the slickest thing we've seen in years. This adjustable box simply uses your electric temperature gauge as the sending unit to control your cooling fan.
If you have a mechanical temp gauge, the 91064024 includes a temperature sender. Installation is as simple as hooking up seven wires and then turning a knob on the end of the box to set the on and off temperatures for the fan. 12 volt. 4 3/4" x 3" x 1 1/4".
Both units feature a built-in heavy duty relay to provide maximum power to your fan and it comes with a tiny LED lamp to let you know when the fan is running plus a fuselink to protect the wiring between the temperature control unit and the fan.
