WIRING OPTIONS
There are a few options on how to activate (turn on) your new Electric Fan Assembly.
1.
Manual Switch - Install a switch in the passenger compartment and turn on Electric Fan as desired.
2.
Electric Fan Thermostat Switch
A.
Adjustable Thermostat - Allows an adjustment range for you to determine optimal turn on temperature.
B.
Pre Determined Temperature - Thermostat has a pre determined temp. from the factory that determines turn on temp.
We recommend using two thermostats therefore activating the low speed at an earlier temperature then the high speed.
Please visit www.derale.com for available thermostat options or visit your local retailer.
Important: When purchasing a thermostat always consider the maximum amp draw. Some thermostats are not designed to
properly handle higher amperage fans.
Note: When installing the Electric Fan with a Thermostat always follow manufacturer's instructions for specific details. In some
cases you will not need the supplied relay harness.
RELAY WIRE HARNESS MOUNTING

Taking into consideration fan placement and wire routing requirements, choose a convenient location.
Avoid mounting near HOT engine components.
