end. Terminating connections seal around the outer
jacket so that the inner conductors are isolated
completely from the environment. Cable assemblies
may have two or more ends.
WIRING HARNESS assemblies (fig. 2-86)
serve two purposes. They prevent chafing and
loosening of terminals and connections caused by
vibration and road shock while keeping the wires in a
neat condition away from moving parts of the vehicle.
Wiring harnesses contain two or more individual
conductors laid parallel or twisted together and
wrapped with binding material, such as tape, lacing
cord, and wire ties. The binding materials do not isolate
the conductors from the environment completely, and
conductor terminations may or may not be sealed.
Wiring harnesses also may have two or more ends.
Wires in the electrical system should be identified
by a number, color, or code to facilitate tracing circuits
during assembly, troubleshooting, or rewiring
operations. This identification should appear on wiring
schematics and diagrams and whenever practical on
the individual wire. The assigned identification for a
continuous electrical connection should be retained on
a schematic diagram until the circuit characteristic is
altered by a switching point or active component.
