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.
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.
