AC106604

Indicates representative vehicle
body ground point. (Same
number as that of ground point in
GROUNDING LOCATION).

Indicates harness junction where
wire diameter or color changes.

In case two or more connectors
are connected to the same de-
vice, markings indicating
the same connector is
connected by a broken line.

Indicates terminal number.

Indicates intersections at
which the lead wires are
not connected.

Indicates intersections at
which the lead wires are
connected.

Indicates input/output
to/from control unit
(current flow direction).

AE

Indicates that the diagram comes
from which belongs to the
block in the same circuit.

Indicates a wiring connector which is inside
the equipment and which is not shown in
the wiring harness configuration diagram.

Example C-15-2

Indicates a connector
which is inside the
equipment, numbered
in order starting from 1.

Indicates the connector number shown in
the wiring harness configuration diagram.

Bi-directional arrow indicates
that current flows in both direc-
tions due to control by an ECU.

Indicates that the terminal is a
spare one if the device (sensor
in this case) is not provided.

Connector
and terminal
marking

1

The male and female terminals
are indicated as shown. The
connector with male terminal(s)
is called as male connector and
indicated by two connector
contour lines, while the
connector with female
terminal(s) is called as female
connector and indicated by
single connector contour line.

The symbol indicates the
connector is viewed as shown.
At a device connection, the
connector symbol on the device
side is shown. For an
intermediate connector, the
male connector symbol is
shown. For spare connectors
and check connectors, no
device is connected, and so the
harness-side connector symbol
is shown for these connectors.
However, a data link connector
is exceptional.

Connection between a device
and the harness is either by
direct insertion in the device
(direct connection type) or by
connection with a harness
connector furnished on the
device side (harness
connection type). The two types
are indicated as illustrated.
