Wiring the Fan Continued:
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 AWG) wire. Using a voltmeter, deter-
mine which wire coming from the compressor is the
positive
(+) wire trigger wire. Use the 3-way BLUE 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.
8.
(OPTIONAL)
For manual switch operation, use Flex-a-lite p/n 31148. Connect the switch as shown on the wiring
diagram. Connect the “M” terminal on the control module to the “1” terminal on the switch. Connect the “2” terminal
on the switch to a positive (+) 12-Volt power source. Connect terminal “3” on the switch to a good ground (for switch
illumination).
Note: To prevent thermostatic activation, if only manual switch operation is desired, omit the lead to the
(+) terminal of the control box. “B”, “G”, “M+” and “M-” must remain connected. If not using a Flex-a-lite manual
switch,
DO NOT CONNECT
a ground wire to the switch!
9.
Locate the inlet hose from the engine to the radiator. Insert the probe through the radiator fins near the inlet hose.
Install the black insulator cap on the back side of the radiator, this will help hold the probe in place.
10.
If you disconnected any hoses or drained coolant to install the fan, reconnect ALL of the hoses and refill the radia-
tor. Press the control knob (included in the wiring kit) onto the control box shaft. Turn the knob
clockwise
until it stops.
Reconnect the battery and start the engine and allow it to idle. Using a hand-held thermometer (positioned near the inlet
hose) or the vehicles temperature gauge, monitor the temperature. When the coolant temperature is
slightly
above
normal or desired temperature, turn the knob
counter-clockwise
just until the fan turns on. From now on, the fan should
activate at this temperature setting. Adjust as necessary to maintain desired temperature.
