Flex-a-Lite 432 Lo-Profile S-blade Fan - Manual (Page 2)

Wiring Instructions Model #412 & #432
FOLLOW THESE INSTRUCTIONS CAREFULLY TO AVOID DAMAGING THE CONTROL UNIT,
FAN MOTORS, AND YOUR VEHICLE! WHEN CRIMPING WIRES, ALWAYS USE A QUALITY
CRIMPING TOOL (DO NOT USE PLIERS OR OTHER DEVICES).
Step 1: Locate mounting point for control
Locate a mounting point for control near inlet side of radiator. Control needs to be placed within 18” of radiator
inlet hose. You may want to mount next to radiator on fender well. Mount control using screws provided.
Step 2a: Wire the fan motors, for model #412 (refer to Wiring Diagram, below)
Using the yellow butt connectors provided, attach a length of the large diameter (12 AWG) red wire to the col-
ored motor wires at fan. Attach a length of the large diameter (12 AWG) black wire to the black motor wires at
the fan. Once the fan is in place, these will attach to the control module. If mounting the control somewhere in
the engine compartment, leave enough wire to reach the control module, but do not connect yet.

Step 2b: Wire the fan motors, for model #432 (refer to Wiring Diagram, below)
Using the yellow butt connectors provided, attach a length of the large diameter (12 AWG) red wire to the black
motor wires at fan. Attach a length of the large diameter (12 AWG) black wire to the colored motor wires at the
fan. Once the fan is in place, these will attach to the control module. If mounting the control somewhere in the
engine compartment, leave enough wire to reach the control module, but do not connect yet.
Step 3: Connect the motor wires to the control module
(Red wire to the “M+” terminal and black wire to the “M-” terminal).
Note: If you have purchased a model #412 fan, proceed to step 2a; If you have purchased a model #432 fan,
skip step 2a and proceed to step 2b.
Step 4: Disconnect the negative battery lead for safety while finishing the wiring. Use the large diameter red
(12 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 blue
female, ring, and butt connectors provided.
Step 5: Use the large diameter black (12 AWG) wire to run from the negative (-) battery terminal to the “G”
terminal on the control module. Use the blue female connector and ring connector provided.
