WIRING AND HARNESS INSTRUCTIONS
WIRING INSTRUCTIONS
Vehicle Control Harness Installation
1. When laying out a path for routing the vehicle
control harness from its attachment point on the
vehicle battery cable into the cab of the vehicle,
make sure that the path avoids any hot, sharp, or
moving parts of the vehicle. Routing will vary from
vehicle to vehicle.
2. Choose a cab control mounting location that can
be reached by the harness. The location must
be within easy reach of the vehicle operator
without restricting access to vehicle controls or
instrumentation.
Do not mount the control in areas prohibited
by the vehicle manufacturer for reasons of
crashworthiness. See the vehicle's body builder's
book, owner's manual, or service manual for
details. The shaded portions in the illustration
below show the most commonly restricted areas.
NOTE: Use dielectric grease on all electrical
connections.
CAUTION
Before drilling any holes, check both sides
of the material for any wires, fuel lines, fuel
tanks, etc., that may be damaged by drilling.
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.
PICK-UP TRUCK
These instructions are only applicable if you are using
the SP-1675 spreader with the TPR-020/TPR-020-1
Receiver Adapter.
1. Find a convenient location in the cab to mount the
spreader control. Make sure that the area behind
this location has room for wires to be routed and
screws to come through the dashboard. The
U-shaped control bracket can be mounted above
or below the control according to the surface
where it will be mounted.
(Dealers: Contact
customers before mounting control.)
2. Once the mounting location has been established,
mount the control bracket. Assemble the control
to the bracket with the cap screws and washers
included, placing nylon washers between the
bracket and the control housing. Use the provided
screws to mount the bracket to the dash.
3. Find a location along the
fi
re wall where wires and
drilling will not interfere with any parts on either
side of the
fi
re wall. This location will be where the
wires to and from the spreader control will enter
the cab. Mark this location and drill a 3/4" hole.
4. Route the control power cable (PN D6341) from
the battery, along the fender, along the
fi
re wall,
into the cab, and connect to the control. Make sure
that the POWER switch is in the OFF position.
Work back from the control, securing the harness
with cable ties. Stop at the fender. You will need to
disassemble the plug to get the harness through
the
fi
re wall. See the photos on the next page.
5. Connect the control power cable to the battery. If
installing on a vehicle with two batteries, connect
to the primary battery.
6. Coil excess cable in the engine bay. Secure with
cable ties.
7. Route the vehicle harness (PN D6322) from
the rear of the vehicle, along the frame, into the
engine bay, along the
fi
re wall, into the cab, and to
the control. Connect to the control.
CAUTION
Before drilling holes, check to be sure that no
vehicle wiring or other components could be
damaged.
