9.6.1 Removal and Replacement
Remove a wiring harness only if damaged or unusable.
Install a new harness one terminal at a time as the old
harness is removed. Label or tag the terminal locations of
all wires, harness clips, tie wraps and conduit as the old
harness is removed to allow correct installation of the
new harness.
9.6.2 Disassembly
Disassembly of the wiring harness is not recommended
due to the precise arrangement of wires and splice
requirements. If it becomes necessary to replace wires,
use the correct gauge size wiring, and NEVER replace a
wire with a smaller gauge wire.
9.6.3 Cleaning and Drying
Clean a wire harness with a natural bristle brush and the
same detergent used to clean the vehicle. Allow the
harness to air dry. DO NOT allow surface temperatures
to exceed 225° F (107° C).
9.6.4 Inspection and Repair
Replace a harness only if it is damaged or unusable. If a
splice or repair must be made to a wire, always use rosin
core solder to bond wires together. Use heat-shrink
tubing or insulating electrical tape to cover all splices or
bare wires.
9.6.5 Installation
The wiring harnesses are held securely in place by wire
tie wraps, clips or other devices to help prevent chafing or
wearing of the insulation and entanglement with moving
parts. Sections of ribbed plastic conduit have been
installed where wiring or harnesses pass through
openings in the vehicle frame. Always install tie wraps,
clips, conduit, etc., in their original locations to help
prevent damage to the wiring or harnesses.
