C: HOW TO READ WIRING
DIAGRAMS
1. WIRING DIAGRAM:
The wiring diagram of each system is illustrated so
that you can understand the path through which the
electric current flows from the battery.
Sketches and codes are used in the diagrams.
They should read as follows:
• Each connector and its terminal position are indi-
cated by a sketch of the connector in a disconnect-
ed state which is viewed from the front.

Viewed from this direction
• The number of poles or pins, presence of a lock are indicated in the sketch of each connector. In the
sketch, the highest pole number refers to the number of poles which the connector has. For example, the
sketch of the connector shown in figure indicates the connector has 9 poles.
