BEFORE BEGINNING THE INSTALLATION,
DISCONNECT THE NEGATIVE (-) CABLE
FROM THE VEHICLE’S BATTERY
INSTALLATION INSTRUCTIONS
1. Install wire terminals or connectors appropriate for your specic
application to the ends of the red, yellow, and black wires. Be sure to
protect the connections with heat shrink or electrical tape.
2. Determine an appropriate mounting location for the fan controller.
The controller should be mounted away from extreme heat sources,
such as exhaust headers. Using the brackets as templates, mark
the location of the mounting holes and drill four (4) holes with
a 5/32” drill bit. Mount the fan controller with the four (4) supplied
#10 screws.
3. Determine an appropriate mounting location for the self-resetting
circuit breaker. The circuit breaker should be mounted away from
extreme heat sources, such as exhaust headers. Using the bracket
as a template, mark the location of the mounting holes and drill two
(2) holes with a 7/64” drill bit. Mount the circuit breaker with the two
(2) supplied #6 screws.
4. Make the connections as shown in the wiring diagram.
(Shown on page 3)
The red wire from the controller is the 12V (+) input wire and must
be connected directly to the battery’s positive (+) terminal.
The black wire from the controller is the controller ground (-) and
must be connected directly to the battery’s negative (-) terminal.
These wires must be connected directly to the battery to ensure the
controller receives a clean signal.
The yellow wire is the output signal from the controller and gets
connected to the fan(s) positive wire. The fan(s) may be grounded
either directly to the battery negative (-) terminal or to a chassis
ground. The total amp draw of the connected fans must
not exceed 50A.
The green wire from the controller is the optional A/C override
circuit. If using the A/C override circuit, splice the green wire into
the 12V (+) wire from the A/C compressor. This will turn the fans on
when the A/C is turned on, even if the coolant temperature is below
the controller’s activation temperature. Alternatively, the green wire
can be connected to a 12V switch to be used as a manual override.
When the A/C override circuit is activated, the fan(s) will turn on at
30% speed until the coolant temperature reaches the controller’s
activation temperature. Once the activation temperature is reached,
the fan(s) will then increase from 30% to 100% speed.

5. Connect either the supplied push probe temperature sensor or
the supplied probe temperature sensor to the sensor connector
plug from the fan controller. Install the temperature sensor as close
to the coolant outlet on the radiator as possible. If using the push
probe sensor, fully insert the probe into a row of ns. If using the
NPT probe sensor, wrap the sensor threads with Teon tape before
installing the sensor.
6. To adjust the activation temperature of the controller, remove
the rubber plug on top of the controller and use a small athead
screwdriver to adjust the dial. At the lowest setting, the fan(s) will
turn on at 10% speed when the sensor reads a temperature of
approximately 110°F. The fan(s) speed will adjust as the coolant
temperature changes. The highest setting will turn the fan(s) on at
approximately 190°F. The controller’s activation temperature can be
adjusted within this range by turning the dial. Once the dial is set to
the desired setting, replace the rubber plug into the controller.
7. If your vehicle is running too hot, adjust the dial counterclockwise
to lower the controller’s activation temperature. If your vehicle
is running too cold, adjust the dial clockwise to increase the
controller’s activation temperature.
8. Ensure all wires are routed and securely fastened away from
any moving components. Reconnect the negative (-) cable from the
vehicle’s battery. The installation is now complete.
Congratulations! You have nished your installation!
