Electrical Assembly - Vehicle Harness
CAUTION: Always perform the vehicle wire harness assembly
with the vehicle off and the keys out of the ignition. Use
caution when testing the electrical wires for the vehicle's
headlight functions.
Note: A second vehicle wire harness is being introduced for the 2001-02
season. This design contains a two piece harness connected by a head-
light relay. The new design integrates the plow lights and power functions
into the new rocker and joystick control stations and improves lighting.
1.
Begin the installation of the electrical harness under the hood. Insert the
WHITE POWER CONNECTOR & RED POWER WIRE (with FUSE) end
of the harness through the driver's side fire wall access panel into the
vehicle cab. Note:You may need to widen an opening or cut access to the
cab interior to facilitate the assembly.
2. Loosely position the remaining portion of the harness over the driver's
side fender well and in front of the radiator core support. Position both
of the large, gray VEHICLE HEADLIGHT CONNECTORS near the truck
headlights and the smaller, black PLOW HEADLIGHT CONNECTORS
near the grill of the vehicle.
3. If applicable, plug the 9 RECEPTACLES, from the vehicle harness that
contain the gray headlight connectors, into the HEADLIGHT RELAY.
See the illustration to the right. Connect the GREEN & YELLOW wire,
from the vehicle harness with the molded power plug, to the remaining
spade on the relay. Securely mount the relay to the vehicle.
4. Proceed to remove the front directional light assembly on the driver's
side of the vehicle. Feed the VIOLET, turn light wire and GRAY, run light
wire from the wire harness through the opening in the directional light
housing. At this point, use a test light or ohm meter to determine the
proper wires in the vehicle's electrical system to splice into. Once you
have identified the proper wires, position one end of the turn or run light
wire into a SPLICE LOCK CONNECTOR provided. Attach the vehicle
wire to the opposite side of the splice lock connector. Complete the splice
by pinching both wires together and locking the connector. Repeat the
splice procedure for the remaining wire. The passenger's side directional
light assembly requires the same installation; however, only one wire, the
PINK, turn light, needs to be spliced.
5.
Connect the vehicle headlights to the vehicle wire harness using a head-
light adapter kit. Due to differences in the construction of the adapter kits
and the various make and model vehicles you will be servicing, the head-
light adapter kits are not packaged with your snowplows. Review the list
of available light adapters to the right. To place an order for headlight
adapter kits, contact our Customer Service Department at 1-888-680-8600.
Begin the adapter kit installation by removing the existing vehicle head-
light connector from the headlight. Attach the HEADLIGHT ADAPTER
CONNECTOR to the existing vehicle headlight connector. Next, plug the
BLACK, FIVE-PIN CONNECTOR on the headlight adapter into the gray,
five-pin connector on the vehicle wire harness. Lastly, plug the HEAD-
LIGHT ADAPTER CONNECTOR into the vehicle headlight receptacle.
Note: If more than one plug is present, match the colors of each connector
(ie gray to gray, black to black, Chevrolet daylight running is clear to gray).
Repeat the installation for the opposite headlight.
