4. When operating vehicle without plow attached, install
weatherproof cover onto connector to protect electrical
contacts. (See Figure 1-5).

Install Control Harness
1. Run the 3 terminal connector on the receiver unit
around the reservoir and along the left A-frame angle
toward the vehicle.
2. Determine a routing for the 12 ft. long harness from
the vehicle bumper at the left side of the power pack
through the vehicle engine compartment to the cab of the
vehicle.
3. Look for an existing hole, with a rubber grommet, in
the vehicle firewall. The hole must be 5/16" diameter or
larger.
.
4. If an existing 5/16" hole is not available, look for an
area to drill a 5/16" hole that satisfies these conditions;
• DO NOT put a hole in such a spot that will force the
wiring harness, when installed, to interfere or be
routed behind accelerator pedal, brake pedal, clutch
pedal, parking brake or associated linkage.
NOTE: If the hole has to be drilled through carpeting
and/or insulation pull carpet and/or insulation back and
out of the way. After hole has been drilled, mark back
side of carpet and/or insulation where harness will pass
through. Mark location to be cut with a "X" then, using a
sharp utility knife, cut along the "X". Route harness
through drilled hole and cut in carpet and/or insulation.
Reinstall carpet and/or insulation. This will allow for a
clean repair should the plow ever be removed. Simply
place a piece of duct tape on the back side of the carpet
and press into place. This will virtually hide the cut in the
carpet where the harness was routed.
5. Drill a 5/16" hole through the vehicle firewall.
6. Insert wiring harness through rubber grommet and
firewall, then install grommet into firewall.
7. Insert harness wires through boot and then through
strain relief (See Figure 1-6). Push the pins on the end of
each of the three wires into the back side of the
connector (the end with external threads and numbers 1
thru 4 on the surface). The black wire must be inserted
into hole #1 of the connector (note that the holes in the
connector are numbered adjacent to each hole). The
white wire must be inserted in hole #2 and the green wire
must be inserted in hole #3.
Figure 1-6
.
CAUTION
DO NOT drill any holes until a thorough visual
inspection is performed to determine that the
area around the hole to be drilled, on both sides
of the firewall, is clear of any obstacles such as
brake lines, linkage or vehicle wiring.

CAUTION
Keep wiring harness away from moving parts,
sharp edges and areas of extreme heat to avoid
electrical failure and fire.
CAUTION
The three wires MUST be inserted into the proper
holes in the connector. Failure to place the wires
in the proper holes in the connector can result in
failure of the transmitter.
