Fan Wiring Instructions
Step 1: Locate mounting point for control
Locate a mounting point for control near inlet side of radiator. Control needs to be placed within 18"
of radiator inlet hose. You may want to mount next to radiator on fender well. Mount control using
screws provided.
Step 2: Wire the fan motors (refer to Wiring Diagram, below)
Using the bullet connectors provided, attach a length of the large diameter (12 GA)
red wire to the red
or white motor wires at fan. Attach a length of the large diameter (12 GA) black wire to the black
motor wires at the fan. Once the fan is in place, these will attach to the control module. If mounting
the control somewhere in the engine compartment, leave enough wire to reach the control module,
but do not connect yet.
Step 3: Connect the motor wires to the control module using supplied female connectors
(Red wire to the "M+" terminal and black wire to the "M-" terminal).
Step 4: Disconnect the negative battery lead for safety while finishing the wiring. Use the large
diameter red wire to run power directly from the battery positive (+) terminal to the "B" terminal on the
control module. Connect the fuse holder in-line with this wire, as shown, but do not insert the fuse
yet. Use the blue female, ring, and butt connectors provided.
Step 5: Use the large diameter black (12 GA) wire to run from the negative (-) battery terminal to the
"G" terminal on the control module. Use the blue female connector and ring connector provided.
Step 6: Use the small diameter red wire (14 GA) to connect the "+" terminal on the control module to
a positive power source.
NOTE: Attaching this wire to an ignition-controlled source will shut off
the fan when the engine is turned off. Attach this wire to an uninterrupted (always hot) power
source, allow the fan to continue running after the engine is shut off.
Use the blue female
connector and fuse taps (included) if necessary.
Step 7: (Optional) For air conditioning control (if desired) connect the "C" terminal on the control
module to the
positive wire that triggers the A/C compressor using the small diameter green (14 GA)
wire. Using a voltmeter, determine which wire coming from the compressor is the positive trigger
wire. Use the 3-way connector (included) to tap into this wire and send a signal to the fan control
module. The fan will cycle on and off with the A/C clutch when the A/C is turned on.
