WIRING AND HARNESS INSTRUCTIONS

WIRING INSTRUCTIONS

1.  Take the harness assembly and route from the 

rear of the vehicle to the front. Route the harness 

along the frame and attach to the frame holes and 

frame supports. 

 

It is not recommended to attach to fuel or brake 

lines for obvious reasons. Do not route close 

to exhaust system or engine. Even though the 

hopper spreader uses high temperature wiring, it 

still could melt under extreme heat and short the 

spreader electrical system, as well as the vehicle 

electrical system.

2.  Mount rear plug on bumper using supplied 

fasteners. Locate plug toward the center of the 

bumper to reduce the amount of debris the tires 

will throw to the rear.

NOTE: Apply a small amount of dielectric grease 

to the plug. Try to mount plug facing upward to 

help keep plugs tightly sealed.

3.  Secure harness from the rear to the front using 

heavy duty cable ties or frame clips along the 

frame, and lighter duty cable ties everywhere else.

4.  Lay out harness portion that connects to the 

battery along the fire wall and fender well. Do 

not connect power leads to battery yet. Drill a 

3/4" hole in the fire wall or use existing access 

hole for the control portion of the harness. Route 

the connector and harness through the hole. 

 

Be sure to check the area on the other side of 

the fire wall to make sure you are not going to 

drill into the vehicle harness or a control module. 

Generally, either side of the steering wheel is a 

good location to place the hole.

5. 

Connect power leads to the battery: Red 

POSITIVE (+), Black NEGATIVE (–). Always 

connect to the primary battery if using a dual 

battery system. Secure loose loom to any other 

large or medium vehicle harness with medium 

duty cable ties to secure wiring harness.

NOTE: If adding an inline fuse, use a 60 amp slow 

blow (time delay) or a 60 amp relay.

Vehicle Control Harness Installation

When choosing a location for your control, it should 

be mounted within easy reach of the vehicle operator 

and not restricting access to vehicle controls or 

vehicle instrumentation. Do not mount the control in 

areas prohibited by the vehicle manufacturer for crash 

worthiness. See the vehicle's body builder's book, 

owner's manual or service manual for details. The 

shaded areas in the illustration below show the most 

commonly restricted areas.

1.  Install control bracket to control using nylon and 

steel washers and cap screws.

2. 

Connect the harness to the back of the control 

and mount to a suitable location. Cable tie 

loose control harness and move to the engine 

compartment. Do not mount close to any heater 

vents.

3. 

Push the ON/OFF switch on the control to check 

for power. After power has been confirmed, 

push the ON/OFF switch again to turn OFF. The 

electrical portion of the installation is complete.

NOTE: Use dielectric grease on all electrical 

connections.

 CAUTION

Before drilling holes, check to be sure that no 

vehicle wiring or other components could be 

damaged.

 CAUTION

Do not alter, modify or install additional 

components in shaded areas shown below. 

Failure to comply may interfere with airbag 

deployment or cause injury to operator in an 

accident.
