Batteries normally produce explosive gases
which can cause personal injury. Therefore, do
not allow flames, sparks or lit tobacco to come
near the battery. When charging or working
near a battery, always cover your face and
protect your eyes, and also provide ventilation.
Batteries contain sulfuric acid which burns skin,
eyes and clothing.
Disconnect the battery before removing or
replacing any electrical components.
CAUTION
Always disconnect the battery before removing
or replacing electrical components such as a
motor relay or battery cable.

Except as noted, parts to be installed are found in
hydraulics box.
Plow may be removed from vehicle for installation of
electrical components.
1. Identify wires for the parking lamp on the driver-side
and the turn signals on both sides of the vehicle.
Attach a black self-stripping bullet receptacle
connector (found in harness kit) to each of these
three wires.
NOTE: Use dielectric grease to prevent
corrosion on all under hood electrical
connections. Fill receptacles and lightly coat
ring terminals and blades before assembly.
2. Remove NEGATIVE battery cable from battery.
NOTE: During electrical installation, the LONG
BATTERY GROUND CABLE (no stripe) MUST BE
GROUNDED TO THE NEGATIVE BATTERY
TERMINAL.

3. Find a location for the motor relay where it will be
protected from road splash and within 18" of the
vehicle primary battery. (See Photo 1.)
7. Attach cable to motor relay terminal with a lock
washer and a 5/16"-24 jam nut. Attach cable to
battery POSITIVE terminal with hardware provided.
(See diagram and instructions below.)
On vehicles equipped with diesel engines attach
using existing clamp hardware.

5. Route 22" battery cable between a large motor
relay terminal and the POSITIVE battery terminal
taking care to avoid sharp edges and hot or moving
parts.

14. Find a grill/bumper location on driver-side for the
vehicle harness (similar position to battery cable
mount). See Steps 9 and 10 above for how to
install. Route vehicle harness through grill or
bumper and around, or through radiator bulkhead
(drill 5/8" hole if needed) into engine compartment.
8. Stretch rectangular openings of plug cover straps
(found in harness kit) over harness connector ends
of long battery cable assembly (found in hydraulics
box) and vehicle harness (found in harness kit).
Place plug covers over harness ends.
15. Route the wires that break out of the vehicle
harness to the area behind the driver-side
headlamp. Route rest of harness to the firewall. Drill
a 5/8" hole through the firewall in a convenient
location away from hot or moving engine parts.

16. All vehicles with DRL’s - Insert fuse holder on pink
wire of DRL Adapter Kit (P.N. 61584) through firewall
first. Route end of pink wire with receptacles to area
of driver-side headlamp.
Plug Cover
17. Feed vehicle harness fuse holder through hole and
then feed the plastic connector and harness through
to the cab. Disassembly of the fuse holder may
make it easier to pass through 5/8" hole.
9. Find a location in the vehicle grill on the battery side
for mounting the battery cable connector. The best
location is at least 10-1/2" from the center of the
grill and at a convenient height for connecting the
plow plugs.
18. Route brown/red and orange/black wire loom to
motor relay.
19. Attach the brown/red and orange/black wires small
ring terminals to separate small terminals on motor
relay using a lock washer and #10-32 nut for each
connection.
10. Allow connector of each harness to hang out in front
of grill or in bumper openings. Allow enough cable
so it is easy to mate and remove connector. Secure
with long cable ties (found in mount box).
20. Route the 24" long orange/black wire with 3/8" ring
terminal to battery NEGATIVE post. DO NOT
attach wire to battery at this time.
11. Route battery cable through the grill or bumper at
the selected location and through or around the
radiator bulkhead to motor relay taking care to
avoiding sharp edges, and hot or moving parts.
For MVP® Blade Installation, Continue on Page 9.
21. Inside the cab, route vehicle harness connector to
solenoid or CabCommand control and couple the
connectors together.
12. Attach cable with red stripe to the unused large
terminal on the motor relay, and secure it with a
lock washer and 5/16"-24 jam nut.
22. Reconnect vehicle ground cable to NEGATIVE
battery along with the all black plow battery cable,
orange/black wire and the small black park or turn
harness wire.
13. Route cable without a stripe directly to the
NEGATIVE battery terminal (carefully separate the
two cables as needed to reach the battery ground
connection). DO NOT reconnect the battery
ground at this time.
