Perhaps one of the least understood parts of installing an electric fan: Installing and wiring the controller. This Flex-a-lite controller turns the electric fan on and off according to the coolant temperature, and you can adjust where the fan turns on from approximately 180-240 degrees F. No relays are required if you use our controller with our electric fan. Wiring the controller is simple, and following our directions will give you years and years of trouble-free operation.
