RELAY WIRE HARNESS
BLACK Wire: Using a Red #10 Ring Terminal and #10 Sheet Metal Screw supplied, attach the Black wire to a good Chassis
Ground (-).
RED Wire: Using the Blue 5/16” Ring Terminal, attach the Red wire directly to Positive (+) terminal on the vehicles battery.
YELLOW Wire: Using a Blue Butt Connector, Blue Female Connector & extra wire supplied, attach the Yellow wire to EITHER
terminal on the Thermostat Switch.
GREEN Wire-Override Circuit (Optional):
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 Switch as it simply overrides all other functions. If you choose not to use this
option, cut any exposed copper and tape or shrink tube the end of the wire.
ORANGE Wire: Using a Blue Butt Connector supplied, attach the Orange wire to the Grey wire on the Electric Fan Assembly.
BLUE Wire: Using a Blue Butt Connector supplied, attach the Blue wire to the Brown wire on the Electric Fan Assembly.
A/C Override – Using a Blue Wire Tap supplied, attach the Green wire to the Positive (+) lead on the vehicles air conditioning
compressor.
Manual Switch Override –

VEHICLE TESTING
1. Before starting the vehicle, make sure all wires are safely zip tied and away from HOT or moving components.
2. Start the vehicle.
3. If the Override function is being used, either turn on the vehicles air conditioning or flip the manual switch to the ON
position. The electric fan should start immediately.
4. Turn off the Override function and allow the engine to warm up to operating temperature.
5. Allow fan to turn on and cycle off before test driving the vehicle.
TROUBLESHOOTING Q&A
Q: Why doesn’t the electric fan turn on when I use the Override function?
A: To quickly test the Override function, disconnect the Green wire and run a jumper wire directly to the Positive (+) terminal on
the battery. The electric fan should start immediately. If fan started, reattach the Green wire to the proper (+) wire on the A/C
Compressor or Manual Switch.
Q: Why doesn’t the fan turn on automatically?
A: The Thermostat Switch is 100% tested from the factory.
1. Check all electrical connections.
2. Check the Chassis Ground connections to make sure all paint is sanded off and you are getting a good metal to metal
contact.
Q: Why does the electric fan run after the vehicle has been turned off?
A: Check the wire going from the Thermostat Switch to the Ignition Switch. This wire is most likely connected to a constant
Power source. Disconnect the wire and attach it to a Switched 12V Ignition source.
