Instructions / Assembly
B. ELECTRICAL INSTALLATION. Refer to Figure 2.
If routing wires underbody to the rear of the chassis, it is
recommended to route the wire to the inside of vehicle
frame rail. Secure the wires to the frame or OEM harness
with appropriate strapping or fasteners.
CAUTION: Some vehicles are designed to operate with
exhaust temperatures as high as 1800° F. This can easily
damage any wires which are routed too closely or allowed
to come in contact with any portion of the exhaust system.
Be certain all wires are securely installed away from the
exhaust system.
1.) Locate the wire harness and begin to route it from the rear
of the vehicle to the front. The molded rubber plug indicates
the rear of the harness, closest to the spreader. Use frame
holes and frame supports as lashing points. Do not attach
to fuel or brake lines. Avoid wire-runs along exhaust system
or hot engine parts. Melting damage to the harness can
occur in the proximity of extreme heat.
2.) Mount the rubber plug under the rear bumper.
Position this plug toward the center of the vehicle.
3.) Place the Harness portion that connects to the
battery along the firewall and fender well, but do not con-
nect yet.
4.) Drill a 1" diameter hole through the firewall. This hole will be
used to route the controller portion of the harness into the
vehicle. Before drilling always check to see what is on the
other side.
5.) Push the controller portion of harness through the hole in
the firewall that was previously drilled. NOTE: The control-
ler end will have 2 plugs on it, but only 1 plug can pass
through the firewall at a time.
6.) Move to engine compartment. Connect power leads to bat-
tery: RED WIRE (+) positive, BLACK WIRE (-) negative.
Coat the connections with dielectric grease to prevent cor-
rosion and build up. Check harness marked ‘battery’ for
voltage by temporarily removing the red tape affixed to it.
7.) Connect the blue wire from pigtail to brake light. Connect
white wire from pigtail to optional vibrator harness if equipped.
Connect red wire on pigtail to a 12 volt keyed accessory.
Connect black ground wire to ground. Connect white jumper
wire to the back of the controller marked motor white wire.
Connect red jumper wire to the back of the controller marked
battery red wire wire. The two red wires from the main con-
nector can now be connected to the two jumper wires.
(Note: wires will only connect one way) ANY ATTEMPT TO
JOIN THE CONNECTORS IMPROPERLY, FOR EXAMPLE
MALE TO MALE, COULD SHORT OUT THE CONTROL-
LER.
Misconnection resulting in a damaged controller is not
covered by warranty.
8.) Select a suitable location to mount the controller. After mount-
ing verify that the power switch is in the off position.
9.) Coil excess wire and use wire ties to secure it to a safe
location.
10.) Mate the plug coming from the spreader unit to the plug
previously installed under the rear bumper.
11.) Make sure that feed screw/spinner area of the spreader is
clear of obstructions. Turn power on at the controller and
verify that the spreader is operating in all modes. Looking
down on the impeller from the rear of the vehicle, determine
that the impeller is turning counter-clockwise. Unit may now
be operated.
Failure to follow these precautions could cause the red (output) wire
from the Speed Control to make contact with ground, causing the
transistor to burn up. Any grounding or shorting of the red (output)
wire which results in a burned transistor is not covered by warranty.
CAUTION
READ THIS ! . . Serious damage to Speed Control will
result if the following precautions are not followed:
1. Do not install Speed Control until all other wiring is
installed and Motor is test-run.
2. Be certain to connect red wire to (+) terminal of
Motor. Connecting to (-) terminal will burn up Speed
Control Tape this (+) connection so it cannot
accidentally be grounded.
3. After wires are in place, but before connecting Speed
Control, connect a jumper wire from the red wire #48
to the red wire #46. The motor should run, indicating
proper grounding and wire installation. Remove
jumper wire.
4. After the Motor has successfully been test run, the
Speed Control can be installed. Do not allow the
red wire from the control to accidentally contact any
grounded object, including the control case itself.
