Using the Blue Butt Connector provided, attach the Blue Positive (+) fan wire to the on Relay #2.
Using the Blue #10 Ring Terminal and #10 Sheet Metal Screw provided, attach Black wires coming from

Using the Blue 5/16” Ring Terminal provided, attach the Red wire directly to the vehicles Positive (+) battery
terminal.
Using the Blue Butt Connector provided, attach the Yellow Wire to wire on the 180° Thermostat Switch.
Using the Red Butt Connector, Blue Wire Tap Connector and Wire provided, attach the remaining
Thermostat Switch Wire to a Positive (+) switched ignition source.
If the Yellow Wire is connected to a constant power source (battery) the electric fan will run after the vehicle has been
shut off and could run down the battery.
See Electric Fan Wiring
The Green Wire is designed to work in two different configurations. When used, this will allow the fan to be turned on
regardless of the temperature of the thermostat as it simply overrides all other functions. If you choose to not use this option,
cut any exposed copper and tape or shrink wrap the end of the wire.
