Temperature Sensor Connection
The FAN-PWM can be used with most vehicle’s original temperature sensor
circuits and aftermarket electric temp gauges. This eliminates the need for an
additional sensor. Some older cars’ sensors (as those circa the 1970’s) may not
work. If you experience problems, please call our technical support line for as-
sistance 1-800-454-7725.)
Vehicles With known issues:
• Ford modular engines coolant/head temp (4.6/5.4L) range switching @ ~200 degrees
• GM Duramax (could be other new GM also) multi range switching @ ~160 degrees
With these sensors the same voltage will exist at multiple temperatures. If you
set the controller above the switching point of the sensor range it will techni-
cally work. The problem is that the fan will turn on at cold startup initially, turn
off, before coming on again at the proper temperature.
• Please see the PROGRAMMING section on pages 11-14.
• If using this type of sensor, the SPAL FAN-PWM must be programmed to your desired
temperature points as the default settings will not be properly calibrated.
Note: Both large and small gauge ground wires must be grounded.
Single Fan: Please see SINGLE FAN WIRING instructions on Page 16 and 17.
Dual Fan: A dual fan set-up requires a Fan Relay Harness (SPAL part number
FRH) to power the secondary fan. Please see DUAL FAN WIRING
instructions on Page 18 and 19
