Electrical Assembly - Plow Harness

Electrical Assembly - Plow Harness

1.

Begin the electrical assembly by connecting the RED POWER WIRE
from the PLOW ELECTRICAL HARNESS to the PUMP motor terminal
stud using the hardware provided on the pump. Note: The red power
wire contains an end ring terminal too large for the pump motor stud.
Remove the end ring terminal from the harness and replace it with
the 1/4" DIA. END RING TERMINAL located on the pump motor
terminal stud.

2.

Next, remove the bottom bolt, lock washer and internal/external tooth
lock washer from the rear pump mount bracket. Route the BLACK
GROUND WIRE (from the harness) under the pump on the driver’s
side of the A-frame. Align the tooth lock washer and end ring terminal
over the hole on the bracket and secure them with the lock washer
and bolt.

3.

The manifold contains a red COIL WIRE HARNESS that must be
grounded to the A-frame. Locate the 3/8" end ring terminal on this 
harness and secure it to the passenger’s side manifold mount bracket.
Use the existing manifold mount hardware to secure the ground. Note:
The internal/external tooth lock washer provided should install against
the mount bracket to provide a solid ground.

4.

Remove the hex jam nut and external tooth lock washer from the
POWER HITCH CONNECT/DISCONNECT TOGGLE SWITCH and
insert it through the back of the mount bracket on the A-frame. Align
the notch in the key washer on the switch to the notch on the bracket.
Replace the lock washer and jam nut and tighten until the switch is
firmly in place. Next, attach the connector on the plow harness to the
switch. Note: Use caution when making the connection. Switches can
break if done forcefully.

5.

Continue the harness installation by connecting the PLASTIC FEMALE
ELECTRICAL CONNECTOR on the harness to the PLASTIC MALE
ELECTRICAL CONNECTOR found on the coil wire harness.

6.

Finalize the harness installation by positioning the wire harness braid
in the notch on the switch bracket and secure it with a cable tie. Note:
The DIODE LOOP HARNESS should be positioned inside of the 
pump cover.

7.

Next, place the MOLDED RUBBER POWER CONNECTOR (from the
harness) through the hole in the PUMP & MANIFOLD COVER. Position
the cover over the protective toggle switch hood. Align the front and
rear holes in the cover with the U-NUTS located on the mount tabs.
Secure the pump cover with two 3/8"-16 x 1-1/8" CLAMPING KNOBS.

Congratulations! You have just completed building the finest snowplow
available!  However, the vehicle wire harness still needs to be installed.
That is the focus of the second half of the electrical assembly instruction.

Diode Pack
Mount Bracket

Draw Latch
Toggle Switch
Mount Bracket

The draw latch toggle switch installs through the
rear of the bracket with the protective hood. Align
the key washer with the slot cut in the bracket to
prevent the switch from turning. Secure the
switch with the hardware provided. Note: Use the 
square notch in the bracket (below the protective
hood) to position the braided harness. Use another
cable tie to hold the harness against the bracket.

The Pump Cover Installs Over
The Top Of The Draw Latch
Switch Bracket

To properly secure the pump and manifold cover
on the A-frame, position the cover over the top of
the protective hood on the draw latch switch
mount bracket. Align the holes in the cover with
the U-clips on the welded A-frame tabs. Secure
the cover using two clamping knobs.
