The table lists the nominal sectional areas and
allowable currents of the wires.
CAUTION:
When replacing or repairing a wire, be sure to
use the same size and type of the wire which
was originally used.
NOTE:
The allowable current in the table indicates the
tolerable amperage of each wire at an ambient
temperature of 40°C (1 04°F).
The allowable current changes with ambient
temperature. Also, it changes if a bundle of more
than two wires is used.

Each unit is directly grounded to the body or indi-
rectly grounds through a harness ground terminal.
Different symbols are used in the wiring diagram to
identify the two grounding systems.
