a. The allowable current in the above table indicates the
tolerable amperage of each wire at an ambient temperature
of 40°C (104°F).
b. The allowable current changes with ambient temperature.
Also, it changes if a bundle of more than two wires is used.

6) Each unit is directly grounded to the body or indirectly
grounded through a harness ground terminal. Different
symbols are used in the wiring diagram to identify the two
grounding systems.

7) Relays are classified as normally-open or normally-closed.
The normally-closed relay has one or more contac~s.
The wiring diagram shows the relay mode when the energizing
circuit is OFF.
