PARTS FOR ELECTRICAL CIRCUIT

WIRING

Wire Color
All wires have color-coded insulation.
Wires belonging to system’s main harness will have a
single color.  Wires belonging to a system’s sub-circuits
will have a colored stripe.  Striped wires use the following
code to show wire size and colors.

Example: 0.5 G / R

Red (Stripe color)

Green (Base color)

Wire size (0.5 mm

)

Abbreviations are used to indicate wire color within a
circuit diagram.
