Wiring Diagram

1a. Connect the motor wires to the control module

(Red wire to the "M+" terminal and black wire to

the "M-" terminal).

1b. Disconnect the negative battery lead for

safety while finishing the wiring. Use the large

diameter red (10 AWG) 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 yellow

female, ring, and butt connectors provided.

Part number 31149

Temp. Control Module

1c. Use the large diameter black (10 AWG) wire to

run from the negative (-) battery terminal to the "G"

terminal on the control module. Use the yellow

female connector and ring connector provided.

1d. Use the small diameter red wire (14 AWG) 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 to allow

the fan to continue running after the engine is shut off.

Use the blue female

connector and fuse taps (included) if necessary.

1g. Use the zip ties provided to secure the wires and prevent them from interfering with fan blades,

belts, and pulleys in the engine compartment. Reconnect the battery and insert the fuse provided.

1e. (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, 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 theA/C clutch when the A/C is turned on.

1f. (Optional) For manual switch operation, use Flex-a-lite p/n 31148. Connect the switch as shown

on the wiring diagram (previous page). 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 12v power source. Con-

nect terminal "3" on the switch to a good ground (for switch illumination).

NOTE: To prevent ther-

mostatic activation (if only manual switch operation is desired), omit the lead to the "+" termi-

nal 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!

Step 2: Insert the temperature probe into the radiator fins

Locate the inlet hose from the engine to the radiator. Remove the black insulator cap and insert the

temp. probe through the radiator fins near the inlet hose. Reinstall the black insulator cap.

Step 3: Adjust the temperature control knob on the control box

If you disconnected any hoses or drained coolant to install the fan, reconnect the hoses and refill the

radiator. Press the control knob (included in wiring kit) onto the control box shaft. Turn the knob

clockwise until it stops. Start the engine and allow it to idle. Using a hand held thermometer (posi-

tioned near the inlet hose) or the vehicle's temperature guage, monitor the temperature. When the

coolant temp. is slightly above normal (or desired temp.), turn the knob counter-clockwise just until

the fan turns on. From now on, the fan should activate at this temperature setting. Adjust as neces-

sary to maintain desired temperature.

Install temp. probe near inlet hose... then replace the insulator cap.
