58295 WIRING INSTRUCTIONS
FOLLOW THESE INSTRUCTIONS CAREFULLY TO AVOID DAMAGING THE CONTROL UNIT,
FAN MOTORS, AND YOUR VEHICLE! WHEN CRIMPING WIRES, ALWAYS USE A QUALITY
1. The fan motors are already wired to the Variable Speed Control unit (VSC) for you. Find the thick black wire in the
kit. Determine the length of black wire needed to reach from the negative (-) battery terminal to the short black wire
on the VSC and cut it to length. Attach a large ring connector to one end and use a yellow insulated butt connector to
connect the other end to the black wire on the VSC (see wiring diagrams on next page).
2. Locate the fuse holder. DO NOT INSTALL THE FUSE UNTIL ALL THE WIRING IS COMPLETE. Attach a large
ring connector to one end and a yellow insulated butt connector to the other end of the fuse holder. Attach the ring
connector to the positive (+) terminal of the battery and connect the other end to the thick red wire found in the kit.
Determine the length of wire needed to reach from the fuse holder to the red wire on the VSC and trim appropriate-
ly. Use a yellow insulated butt connector to connect this wire to the red wire on the VSC. You may use the 2 small
screws to mount the fuse holder if desired.
3. Locate the fuse box. Find a circuit that is "hot " when the key is in the "ON" position. NOTE: DO NOT use the day
time running lights or brake/taillight fuse! Attach the included fuse tap to the fuse. Attach a pink female connec-
tor to the thin red wire included and connect to the fuse tap. Trim the wire so that it will reach the VSC. Attach a pink
female connector to the end of the wire and connect to terminal #9 on VSC.
4. Locate the wires going to the A/C clutch. Determine whether the clutch is activated by a negative (ground) or posi-
tive signal. Connect the signal wire to the supplied thin green wire by use of a piggyback connector. Determine length
needed to reach VSC and trim the wire to length. Attach a pink female connector and connect this wire to terminal #8
if the trigger wire is positive, and terminal #7 if the trigger wire is negative.
5. Locate the temperature probe. Gently push probe through fins in radiator as close to the upper radiator hose as
possible, leaving about ¼" of the probe protruding out of the core. The rubber cap will not be used in this application.
Determine length of wire needed to reach VSC. IMPORTANT: Strip the insulation back about 1" and fold the wire
onto itself to effectively double the thickness of the wire before connecting the pink female connectors. Then attach
these wires to terminals #10 & 11. Both wires need to be connected but it doesn't matter which wire goes to each
terminal.
6. If manual switches (Flex-a-lite #31148) have been purchased, attach them as follows: To override engine tem-
perature to turn fans off, connect the switch to terminal #5 on VSC to send a negative (-) signal. To override engine
temperature to turn fans on, connect the switch to terminal #6 on the VSC so that a negative (-) signal is sent.
Install the temp. probe near the inlet
hose, leaving ¼" of the probe pro-
truding from the core.
