Wiring – Wire color
All wires have color–coded insulation.
Wires belonging to a system’s main harness will have a
single color (1). Wires belonging to a system’s subcircuits
will have a colored stripe (2). Striped wires use the
following code to show wire size and colors.

Wiring – Wire Size
The size of wire used in a circuit is determined by the
amount of current (amperage), the length of the circuit,
and the voltage drop allowed. The following wire size and
load capacity, shown below, are specified by AWG
(American Wire Gauge) (Nominal size means
approximate cross sectional area (1).)

WIRING SYSTEM
Fuse
Fuses are the most common form of circuit protection
used in vehicle wiring. A fuse is a thin piece of wire or strip
of metal encased in a glass it or plastic housing. It is wired
in series with the circuit in protects. When there is an
overload of current in a circuit, such as a short of a
ground, the metal strip is designed to burn out and
interrupt the flow of current. This prevents a surge of high
current from reaching and damaging other components in
the circuit.
Determine the cause of the overloaded before replacing
the fuse.
The replacement fuse must have the same amperage
specification as the original fuse.
Never replace a blown fuse with a fuse of a different
amperage specification.
Doing so can result in an electrical fire or other serious
circuit damage. A blown fuse is easily identified as shown
in the figure.
