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.
The Flex-a-lite illuminated 3-way switch allows for
in-vehicle control of your fan. By directly connected
to the pins located on the controller, you can shut
your fan o during water crossings, or keep the fan
running at 100% power for towing up steep roads.
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.
3. Strip one end of the included red
wire (black wire for part #31149
controller). Crimp an insulated ag
terminal to the wire.
4. 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.
NOTE: If using the 3-way switch
with Flex-a-lite® Cooling Control
Module Part #31149, Turn page
over for wiring diagrams.
1. Connect wires to back of plug and wire to VSC as
shown in diagram below. (FIg. 2)
NOTE: The loop from pin 2 to 5 represents the jumper
lead produced in FIg. 1.
2. Secure and cut all wires to length before connecting
to the VSC. Ring terminals are provided if you choose to
connect 12V power and ground directly to the battery.

1. 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)
NOTE: If using Cooling Control Module Part #31149,
apply previous step to the red wire.
2. Strip one end on both the orange and green wires.
Crimp an insulated ag terminal to each.
