WIRING
Before starting, disconnect the Negative (-) cable on the vehicles battery.
Using the electrical connectors and wire ties provided, follow the instructions below. (See Diagram #3 on reverse side)
Red Wire (harness side): To Positive (+) 12v Battery
1.
Using the Yellow 5/16” Ring Terminal & 10 Ga. Red Wire supplied, connect one end of the red wire to the vehicles Positive (+)
terminal on the battery.
2. Route the 10 Ga. Red Wire now connected to the battery to the Circuit Breaker previously installed and cut the wire to the
appropriate length.
3. Using a Yellow #10 Ring Terminal, connect the 10 Ga. Red Wire to the “BAT” Terminal on the Circuit Breaker.
4. Using a Yellow #10 Ring Terminal, connect the auxiliary side “AUX” of the circuit breaker to another length of 10 Ga. Red Wire.
5. Route the 10 Ga. Red Wire now connected to auxiliary side of the circuit breaker to the Red Wire (harness side) located on
the Dual Fan Controller and cut the wire to the appropriate length.
This unit utilizes an auto resetting circuit breaker to protect the fans
and controller circuit. In the event of an electrical short, the breaker
will “trip” and open the connection between the battery and the
controller. If this happens, turn the vehicle off and let it cool before
restarting the system. The breaker will automatically reset.

HOW IT WORKS
The Derale High Amperage Adjustable Dual Fan Controller is designed to
operate two electric fans at different activating temperatures. Fan #1 is
designed to activate at the desired adjusted temperature (150°F-240°F).
Fan #2 will activate once the vehicle water temperature increases by 15°F.
The fans will deactivate 10°F below each turn-on temperature.
This unit is designed to control 2 electric fans with a
Maximum Draw of 35 Continuous Amps Per Fan.
This controller
using the following Will Not Work
2-speed O.E. Electric Fans: Dodge Viper, Ford
Taurus, or Lincoln Mark VIII. These fans exceed the
amperage & functionality capabilities of this fan
controller.
For proper installation the control module must be
mounted within 5 feet of the vehicle's battery.
