WARNING
When transporting, position plow so as not to block driver
line of sight or plow headlights.
WARNING
DO NOT move the blade or exceed 50 MPH when trans-
porting the plow.
WARNING
DO NOT plow at speeds in over of 14 mph.
WARNING
Always lower blade and power off controller when vehi-
cle is not in use.
WARNING
Always follow the vehicle manufacturers recommendations
relating to snowplow installation.
WARNING
When using on a vehicle with air bags, DO NOT tamper
with, disable or remove any components related to the
operation of the air bags.
WARNING
When using on a vehicle with air bags, DO NOT tamper
with, disable or remove any components related to
the operation of the air bags. Vehicles equipped with
air bags are designed such that the air bags will be
activated in a frontal collision equivalent to hitting a
solid barrier (such as a wall) at approximately 14 mph
or more, or, roughly speaking, a frontal perpendicular
collision with a parked car or truck of similar size at
approximately 28 mph or more. Careless or high speed
driving while plowing snow, which results in vehicle
decelerations equivalent to or greater than the air bag
deployment threshold described above, could deploy
the air bag.

Bill of Materials
The moldboard can be propped on a 4x4 or the edge
of a shipping pallet to get into position for mounting
onto the a-frame. The moldboard should be lifted
and held in place until secured with a crane using the
points shown. The lift frame can be slid forward on
the shipping pallet and raised using a pallet jack to
easily mate with the moldboard (Fig. 2).

1. Attach the Moldboard to the Sector using the Trip
Pin Kit (6) on both the Driver and Passenger Sides.
Do NOT detach the crane as the moldboard is still not
secured.
2. Install the Trip Springs (8) and Trip Spring Hardware
(7) as shown. Tension the trip springs until there is
approximately a .030” gap. It is important that all
springs be at the same level of tension.
3. Install the snow deflector by loosening the fasten-
ers on the top strip of the moldboard. The deflector
fits between the black retainer strip and the stainless
moldboard. Only the OUTER TWO fasteners need to
be completely removed.
4. Install the blade guides (5) as shown.
5. The shoes as installed have been adjusted for ship-
ping and may need to be repositioned after the plow
is mounted to a vehicle.

Drop Foot Deployment
For shipping the drop foot is in the transport position and the lift frame/Aframe are in stacking position. For
mounting, the drop foot will need to be lowered to the deployed position so that the plow can be mounted.
This step requires two people or a winch to rotate the lift frame.
1. Raise the rear of the a-frame approximately 6"-8" from the floor.
2. Rotate the lift frame away from the a-frame until the top plate is approximately parallel to the ground.
3. Pull the drop foot release and lower the drop foot to the ground. Release the drop foot release and pull up on
the drop foot to ensure that it is locked.
4. Allow the lift frame to rotate down and away from the a-frame until the slack is removed from the chain. The
lift frame may be sitting low to the ground at this point but it can be raised during the mounting process using
the jack switch.
Upper Lift Frame Assembly
1. Rest the UPPER LIFT FRAME (2) on the LOWER LIFT FRAME (1) as shown in Fig 7.
2. Loosely install the 3/8 bolts (3) as shown. After ensuring the upper and lower lift frames are aligned, tighten
fasteners.
3. Install the 16160700A Halogen light kit or 16160800 LED light kit (both sold separately) using the included
hardware. If the shock spacer (5) is included with the hardware, it should be installed under the spherical
washer as shown.
4. The plow light harness as shipped is routed through the holes on the back side of the lift frame. The side
marked A is the DRIVER SIDE and the side marked B is the PASSENGER SIDE, correct if necessary. Gently pull
the wires through the holes so they can reach the light connectors.
5. Inspect the lighting connectors to make sure the pins are straight and carefully connect the lights to the plow
light harness. If the connectors are forced together, the pins may become bent.
6. Use the included zip ties to secure the light harness to the inside of the upper lift frame.
Your SnowDogg

Vehicle Side Installation
Plowing is very hard on vehicles. For this reason any vehicle getting a plow mounted to it should be well main-
tained. Before installing a plow, and on a regular basis after, have the following systems checked and repaired as
necessary:
• Braking - The additional weight and frequent starts/stops of plowing require your brakes to be working
at their best.
• Cooling - Transporting the plow can block air flow to your radiator. Keep an eye on your temperature
gage and make sure your cooling system is working as designed.
• Suspension - Plows really work out a front suspension even if you are within your FAWR limit. Have your
suspension components checked regularly.
• Transmission - Snowplow operators probably drive in reverse more than any other driving professional.
Keep your transmission well maintained, and ALWAYS fully stop before shifting from forward to reverse.
• Lighting - Plow lights require the truck lights to be working correctly. Any malfunction on the truck side
will result in a malfunction on the plow side and make troubleshooting much more difficult. Always make
sure your truck lights are working normally BEFORE you start an install.
• Alignment - The vehicle alignment should be checked and corrected AFTER the plow is installed.
Vehicle Specific Mount Installation
Install the SnowDogg
®
Plow Mount required for your application following all instructions in the mount installation
instructions(**). Modification of your vehicles bumper/air dam/fascia may be required and will vary from vehicle
to vehicle.
** The MDII/VMDII plows use the same mounts used for the MD/VMD series. However, due to changes in the lift
geometry, the pushbar should be mounted with the solid round bar at ~10” from the ground. If this is not pos-
sible due to truck interference, the push bar can be mounted lower without impact on plow performance.
WARNING
Check all mounting hardware on a regular basis. Fasteners on plow mounts are subjected to a great deal of
vibration and WILL loosen over time potentially causing the mount or plow to come loose from your vehicle.

Vehicle Side Electrical Installation
The SnowDogg
®
plow has separate harnesses for Hydraulic and Lighting for ease of installation and trouble-
shooting. Either harness can be omitted without affecting the functionality of the other system.
Control Harness Installation
The truck side control harness is routed through the grill, by the battery, and through the firewall to the control-
ler. It is preferable when possible to keep the plow connector on the driver side to make mount/dismount easier
and faster.
It is important that the 15A fused power lead go to an ignition switched source. Hooking direct to an “always on”
source will cause a constant current draw and drain the vehicle battery. If an ignition switched source cannot be
found, any switch rated at 15A can be used to turn off the power.
CAUTION
Keep all connectors greased with dielectric grease on a regular basis to minimize corrosion & potential damage
or wear to the pins. It is critical that all electrical connections be tight and secure. Loose connections on the plow
circuit can cause overheating, component failure, or intermittent opration.

83042233_B
1. Route the CONTROL HARNESS through the truck grill, by the battery, and through the firewall. If no avail-
able opening exists, a ø7/8" hole will need to be drilled through the firewall. Check your truck Owner’s Manual
for details on where this can be safely done. If the hole is drilled, it is critical that a grommet be used to prevent
damage to the wire harness.
2. Mount the MOTOR RELAY in a convenient and secure location on the battery side of the vehicle using the
included self tapping screws.
3. The small RED and BLACK WIRES from the CONTROL HARNESS are connected to the small terminals of the
MOTOR RELAY. It does not matter which wire goes to which terminal.
4. The small BLACK WIRE with the eyelet should be connected to battery ground or a good chassis ground. A
“dirty” ground will cause excessive power draw and can cause malfunctions in the lights and the controller.
5. The RED/WHITE wire will be connected to the LIGHT HARNESS in the next step.
6. The large (4 gage) BLACK WIRE on the CONTROL HARNESS must be connected directly to the NEGATIVE (-)
battery terminal.
7. The large (4 gage) RED WIRE on the CONTROL HARNESS is connected to one of the large terminals on the
MOTOR RELAY. It does not matter which terminal is used.
8. The shorter RED BATTERY CABLE is used to connect the other large terminal of the MOTOR RELAY with the
POSITIVE (+) terminal on the battery.
9. The CONTROLLER CONNECTOR is routed through the firewall.
10. Connect the handheld controller and locate in a convenient location for the operator using the included
mounting hardware if desired.
11. The FUSED ACC POWER WIRE coming off of the controller connector must be connected to an IGNITION
SWITCHED 15A/12V power source. Hooking direct to an “always on” source will cause a constant current draw
and drain the vehicle battery. If an ignition switched source cannot be found, any switch rated at 15A can be
used to turn off the power.

Light Harness Installation
The light harness is split into a RELAY MODULE and a GRILL HARNESS to allow for easy installation.
Connectors have been designed in such a way to prevent installation errors – but be sure to read all instructions.
1. Install the appropriate 1607XXXX headlight adapter (and accessories) using the instructions.
2. Route the GRILL HARNESS through the grill (drivers side preferably)
3. Locate the RELAY MODULE close to either the driver or passenger side headlight (whichever is convenient)
and connect the 8-pin connector to the GRILL harness.
4. Route and connect your 1607XXXX headlight adapters to the RELAY MODULE.
5. Connect the BLACK wire with ring terminal to Battery or a clean Chassis ground. If a chassis ground is used,
it would be best to use the same location used for the CONTROL HARNESS.
6. Connect the purple TURN SIGNAL wires between the harnesses.
a. If your “A” headlight adapter is on the DRIVER SIDE
i. Connect PURPLE/WHITE to PURPLE/WHITE
ii. Connect PURPLE/BLACK to PURPLE/BLACK
b. If your “B” headlight adapter is on the DRIVER SIDE
i. Connect PURPLE/WHITE to PURPLE/BLACK
ii. Connect PURPLE/BLACK to PURPLE/WHITE
c. If you find that your plow turn signals are backwards from the truck – swap the wires.
7. The final configuration steps require you to know if your vehicle is STANDARD or SWITCHED GROUND instal-
lation. MOST vehicles are STANDARD. ALWAYS verify your application on the application guide before configur-
ing. Configuring your harness incorrectly can result in blown fuses and troubleshooting hassles.
Standard Installation
• Connect the ORANGE wire on the RELAY MODULE to the RED/WHITE wire on the CONTROL HARNESS.
This supplies ignition switched power to the light relays.

• Cut open the loom on the GRILL HARNESS near the 8-pin connector to locate the WHITE/BLACK wire.
This wire has male and female connectors in line.
• Disconnect the WHITE/BLACK wires (male and female connectors) from each other on the GRILL HARNESS.
• Connect the ORANGE wire on the RELAY MODULE to the WHITE/BLACK wire on the GRILL HARNESS.
This supplies ground to the relay coils when the plow is connected.
• Connect the WHITE/BLACK wire on the GRILL HARNESS to the RED/WHITE wire on the CONTROL
HARNESS. This supplies ignition switched power to the common wire of the plow lights.
8. With the plow disconnected, check all light functions on the vehicle.
9. Connect the plow and check all light functions on the plow.
Optional Accessory Wires
There are two extra blunt cut wires (RED and BLUE) in the GRILL HARNESS near the 8-pin connector. These
wires are for optional accessories mounted on the plow. They end at the 5-pin light connectors on the plow and
go to both the driver and passenger side light connectors. If these are used, they should be properly terminated.
These wires are suitable for 15A of current.
