Prep & Run Wires
4. Cut a small (~2”) segment o of included black wire.
Strip both ends of the wire and one end of the wire that
was cut from. Twist One end of the small segment to
the long wire, and crimp 2 of the included insulated ag
terminals to the exposed end. (Fig. 1)
5. Strip one end on both the orange and green wires.
Crimp an insulated ag terminal to each.
6. Strip one end of the included red wire. Crimp an
insulated ag terminal to the wire.
1. Determine mounting position for the switch. Look for
a at section of panel that is easily accessible from the
driver’s seat to activate.
2. Check to make sure there are no wires or
electronics directly behind this area. You will also need
a minimum depth clearance of 1-3/4” to clear the switch
body and the wires to attach.
7. Find a suitable location in the rewall of the vehicle
to pass these 4 wires through. If drilling, make sure
to use a grommet on the rewall to prevent abrasive
damage to the wire. Leave enough wire inside the
vehicle to easily reach the switch mounting hole.
8. Cut the green and orange wires to length for
reaching the ag terminals located on the fan
controller. Strip the orange and green wires
and crimp an insulated ag terminal to each.
Attach to associated controller terminals.
NOTE: On Flex-A-Lite fan controllers which only have the
Fig. 1
option for manual on, a relay needs to be wired between
the switch wire and controller as shown in the diagram to
the right.
3. Mark o a rectangular hole 1-1/2” Tall x 7/8” Wide with
masking tape where you plan to mount the switch. If
you can remove this panel from the vehicle, cutting this
hole will be easier. Drill the corners of the marked
rectangle and remove the remaining material with a
small cutting blade and a le. Make sure the hole is clear
of any loose material or sharp lings.

Install & Test
9. Cut the red and black wires to length to reach the
battery. Strip each wire and crimp on the included ring
terminals. Connect the red wire to the positive (+)
battery terminal and the black wire to the negative (-)
battery terminal. NOTE: Depending on your install application, the red wire can also be connected to an ignition
controlled 12V source. Do not tap into headlight wires or
windshield wipers!
10. Inside the vehicle, connect the ag terminals on the
black wire to pins 2 and 5 on the switch, and the red wire
to pin 7. (Fig. 2)
11. Turn your vehicle ignition to the on position. Plug in
the orange or green wire into pin 4 on the switch. Toggle
the switch up towards pin 7; if this does not turn the fan on
remove and replace with the other color wire.
Connect the remaining wire to pin 6.
12. Turn your vehicle ignition o. Make sure all wires are
securely mounted and press the switch until it sits ush
and locks into the vehicle panel.
