6. After the headlight adapters have been installed, attach the POWER
CONTACTOR to the driver's side wheel well or engine fan guard using
two 12-14 x 3/4" hex washer self-drilling screws. Note: Some model
vehicles provide mount locations for accessory components. Connect the
24" BLACK GROUND WIRE to either small terminal on the contactor
and attach the opposite end to the vehicle with one hex washer self-drilling
screw. Locate the BROWN or BROWN/WHITE PUMP SOLENOID
D
ACTIVATION WIRE on the vehicle wire harness and position the eyelet
over the remaining small terminal on the contactor. Secure it with the
washer and nut provided.
7.
Next, connect the BLACK VEHICLE WIRE HARNESS GROUND WIRE
to the negative terminal on the vehicle's battery. Note: The black ground
wire may not be long enough to reach the battery on some vehicles. Use
the 54" BLACK GROUND WIRE EXTENTION provided to reach the
battery. The VEHICLE WIRE HARNESS RED POWER WIRE connects to
either large terminal on the contactor. Complete the electrical connection
by attaching the remaining 72" RED POWER BATTERY WIRE to the open
terminal on the contactor. Note: Depending on the location of the battery,
you may need to shorten the red power wire. Upon determining the proper
length, crimp the provided 3/8" END RING TERMINAL on the wire and
connect it to the positive terminal on the battery.
8. Once the connections to the battery are secured, proceed to fasten the
SPLIT LOOM TUBING to the vehicle. Safely route all harness lengths
around the engine components and attach them to the vehicle with nylon
ties. Extend the PLOW HEADLIGHT CONNECTORS through the grill of
the vehicle and position the HARNESS PLUG and WEATHER CAP
near the bumper.
9. Locate a convenient position to mount the VEHICLE WIRE HARNESS
PLUG MOUNT BRACKET near the driver's side bumper of the vehicle.
This bracket will hold the plug to the vehicle when the snowplow is removed
from the undercarriage. Position the bracket into the slot provided on the
plug. Mount the bracket using two 1/4"-20 x 3/4" hex cap screws and secure
with 1/4" washers and top lock nuts.
10. Return to the driver's side cab interior to install the remainder of the
vehicle wiring harness. Find an accessible location for the PLOW HEAD-
LIGHT SWITCH & BRACKET under the dashboard. Install the headlight
bracket using two self-drilling screws. Insert the headlight toggle switch
Yellow
through the bracket and secure with the hardware provided. Attach all
and
6 color coded wires from the harness to the backside of the switch (Refer
Red
to diagram at the left for proper installation). Connect the RED POWER
WIRE (with 10 AMP FUSE) to a SWITCHED POWER SOURCE with a
minimum of 10 amps. Note: The red power wire MUST be fused and
switched on and off with ignition. Secure all loose wires under the dash.
11. If you received the harness that contains the relay, your electrical harness
does not contain individual receptacles for the toggle switch. A small, two
pin connector is located near the main power connector. Use the PLOW
HEADLIGHT SWITCH 2-PIN CONNECTOR & WIRE LEADS to connect
the plow headlight toggle switch to the harness.
CAUTION: Do not fasten the wire 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.
