Truck Battery On Driver Side
CAUTION: Ensure that the relays will
clear any hood lift/spring mechanisms
before installation.
11. Select an area near the driver's side in-
ner fender to mount the four relay set. Drill
two 1/8" diameter holes and secure the re-
lays using #8 x 1/2" self-tapping screws
from the hardware bag in the parts box.
Apply a light coat of dielectric grease on
the relays before inserting into holders.
NOTE: Always mount the relays with the wires
pointing down to prevent contamination.
Repeat this procedure and mount the three
relay set on the passenger side inner fender.
12. Splice the red with white stripe wire to the
vehicle's switched 12 volt auxiliary electrical
circuit. This will prevent operation of the plow
without the vehicle key being on. This wire
controls the accessary relay that powers the
control joystick and solenoids.
CAUTION: To prevent injury or prop-
erty damage caused by unintentional
plow movement when the key is re-
moved from the vehicle, the red/white striped
wire must be connected to a switched power
source on the vehicle. Connecting to a power
source not controlled by the ignition switch
will allow movement of the plow with the ve-
hicle key removed.
13. Connect the joystick control box to the 7-pin
connector inside the truck cab. Secure the
box at a safe location in the cab with the
strip of hook and loop fastener.
WARNING: Ensure that the motor so-
lenoid and associated wiring will clear
any hood lift/spring mechanisms before
installation.
IMPORTANT: Do not over tighten nuts on the
motor solenoid terminals. Over-tightening causes
premature solenoid failure. Refer to torque specifi-
cations on the solenoid.
