WARNING
Do not drill holes into fuel tanks, fuel lines, through
electrical wiring, etc that may be damaged by drilling.
To insure good performance of your spreader, check the
condition of truck’s electrical system. Using digital volt-
meter, check alternator and battery voltage. With engine
running and head lights and heater fan ON good voltage
reading should fall between 13.0 and 15.3 volts. If volt-
age reading falls out of this range, check and adjust your
electric system.

Electrical Installation
(fig. 2)
NOTE: Always disconnect battery before attempt-
ing to install electrical components on your
vehicle.
• Mount the controller in a convenient location in the
truck cab. It is recommended not to mount the con-
troller directly in front of heat vents.
• Route both wire harnesses into truck cab through
firewall (it maybe necessary to drill holes). Insulate
hole to avoid water leaks.
• Insure no wires are nicked or damaged during
installation.
• Connect the 4-pin connecter on the wire harness to
the control box.
• Connect the 2-pin connector on the power cable to
the control box.
• Lay out a path for the power cable to the bat-
tery, use quick ties to secure power cable.
DO NOT
CONNECT TO BATTERY AT THIS TIME!
• Lay out path for wire harness to the rear of the vehi-
cle. It is recommended to stay clear of the exhaust
system. Excess heat can damage the wire harnesses.
Use quick ties to secure harness to underbody.
• Connect the wire harness to the motor.
• Connect the power and ground cables directly to
the battery (Fig 2).
• Insure all functions of the controller are working
properly.
