Flex-a-Lite 345 Nissan 240SX Fits 1989-1998 - Manual (Page 3)

With the A/C drier relocated, now the fan assembly can be installed.
Lower the fan assembly into place. Make sure the rubber caps fit into
the tabs at the bottom of the radiator as shown (see Detail 8). On au-
tomatic transmission models, it may be necessary to swivel the trans.
oil line clamps down so they clear the bottom bracket. First, tighten the
top screws in place so that they are supporting the weight of the fan.
Then tighten the bottom bolts in place - use the lock nuts to “sandwich”
the bolt to the bracket (refer to detail on previous page).
Before you begin wiring, disconnect the battery negative terminal. First, connect the main power and ground
leads to the fan control unit. Find the fuse holder in the wiring kit. Use a large ring connector to connect the
fuse holder to the positive (+) battery terminal. For your safety, DO NOT INSTALL THE FUSE UNTIL ALL
THE WIRING IS COMPLETE. Use a blue butt connector to connect the thick red wire to the other end of the
fuse holder. Use a blue female connector to attach this wire to the “B” terminal on the fan control unit (see wir-
ing diagram, next page). Use the thick black wire to run a ground wire directly from the battery negative (-)
terminal to the “G” terminal on the fan control unit.
Using the thick red and black wire and the connectors provided, connect the motor wires to the control unit
as described next.
Place both red motor wires side by side and smoothly twist together. Completely insert pair of wires into one
end of a yellow insulated butt connector. Crimp connector to secure. Repeat with black motor wires to anoth-
er yellow insulated butt connector. Insert thick black wire into the open end of butt connector containing the
two red motor wires and crimp connector securely. Insert thick red wire into the open end of butt connector
containing the two black motor wires and crimp connector securely. NOTE: THE BLACK MOTOR WIRES
ARE POSITIVE (+) AND THE RED MOTOR WIRES ARE NEGATIVE (-). FAILURE TO CONNECT THESE
WIRES PROPERLY WILL RESULT IN DAMAGE TO THE FAN MOTORS AND YOUR ENGINE! Connect
the joined red motor wires to the “M-” terminal on the control unit. Connect the joined black motor wires to the
“M+” terminal on the control unit (see wiring diagram, next page).
Find a fused circuit in the engine compartment fuse box that is “hot” (reads 12 volts) when the ignition is turned
on. Use the supplied fuse tap and connectors to run a length of the thin red wire from the fuse to the “+” ter-
minal on the control unit. This will provide ignition-controlled activation - the fan control unit will only be active
when the ignition is turned on.
Find the A/C fan connector you unplugged earlier. Use the wire tap connector to connect the supplied green
wire to the orange/white wire in this harness. Connect the other end of the green wire to the “C” terminal on
the fan control unit.
