C: HOW TO READ WIRING DIA-
GRAMS
1. WIRING DIAGRAM
The wiring diagram of each system is illustrated so that you can understand the path through which the elec-
tric 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 indicated by a sketch of the connector in a disconnected state
which is viewed from the front.

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