ELECTRICAL INSTALLATION – VEHICLE SIDE
CAUTION
Before drilling any holes, check the selected
area for wires, hoses or other obstructions.
1. With the large plug on the electrical harness
placed near the tow hook, under the bumper, route
the harness over the driver-side fender well and
to the fi re wall. Insert the connector end of the
harness through an existing hole in the fi re wall
and into the vehicle cab. If an access hole does
not exist, drill an appropriately sized hole through
the fi re wall in a convenient location away from
sharp edges and hot or moving parts.
NOTE: Keep the snowplow plug and vehicle
connector pins lubricated with a liberal amount of
dielectric grease. Always replace the protective
weather caps when the snowplow is disconnected
from the vehicle.
2. Attach the power contactor (solenoid) to the
driver's side wheel well or engine fan guard using
#12 x 3/4" self-drilling screws.
NOTE: Some model vehicles provide mounting
locations for accessory components.
Always mount the solenoid with the terminals
facing up, for extended solenoid life. Connect
the 24" black ground wire to either small terminal
on the solenoid and attach the opposite end
to the vehicle with a self-drilling screw. Cut the
brown/white pump activation wire on the harness
to length. Strip the end of the harness, and crimp
the eyelet terminal onto it. Attach the eyelet to the
remaining small terminal on the contactor. Secure
it with the hardware provided on the solenoid.

NOTE: Do not fasten the harness to areas that
come in contact with moving engine parts or
possess extreme heat. The harness could become
tangled and/or melt causing electrical failure and
vehicle damage.
3. Connect the vehicle harness ground wire to the
NEGATIVE (–) terminal on the vehicle's battery.
Cut the wire to length, and strip the end of the
wire. Crimp and solder a 3/8" ring terminal on the
wire.
NOTE: The harness should be secured to
the vehicle prior to taking the necessary
measurement.
Measure the distance needed for the power wire
to reach the solenoid. Strip the wire, then crimp
and solder an end ring terminal to it. Connect the
power wire to either large terminal on the solenoid.
4. Strip both ends of the remaining length of red
wire, then attach and solder an end ring terminal
to both. Connect one end of the wire to the open
terminal on the solenoid and the remaining end to
the POSITIVE (+) terminal on the battery.
5. Position the main lighting harness with both
of the truck headlamp connectors near each
truck headlamp and the snowplow headlamp
connectors near the grille of the vehicle.
6. Plug the headlamp ground/relay connector from
the vehicle harness into the connector on the
main lighting harness. Securely mount the relay
receptacles to the vehicle with the terminal wires
facing down and the relays facing up. Installing the
relays in this position will allow moisture to drain
from the relay.
7.
Remove the front signal lamp assembly from both
sides of the vehicle. On the driver's side, feed the
violet (turn lamp) and gray (run lamp) wires from
the main lighting harness through the opening
in the signal lamp housing. Use a test light or
ohmmeter to determine the proper wires in the
vehicle's electrical system to splice into. Position
