1. General Description
A: 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:
IEach connector and its terminal position are
indicated by a sketch of the connector in a discon-
nected state which is viewed from the front, as
shown in figure.
G6M0193
IThe 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 connector has. For example, the sketch
of the connector shown in figure indicates the con-
nector has 9 poles.
