Indicates power source.
Indicates that terminal is conne-
cted via a plate in the relay box.
Each circuit diagram consists of
blocks). The blocks are divided
by page number.
Indicates splice point numbers.
These numbers are identical to
those described in "Splice Loca-
tions."
Indicates the circuit name to be
connected. The arrow indicates
the current flow direction.
Indicates the power supply in
the control unit. If no voltage is
displayed, this indicates battery
positive voltage.
An "X" at the end of a connector
number indicates that the conn-
ector is connected to a central-
ized junction that is shown in the
section "Centralized Junction."
Indicates the connector symbol.
Connectors in the circuit diagram
are indicated in numerical order.
Indicates connector number.
The same number as used in the
wiring harness diagram.
Connector and connector numbers
are shown at the lower part of the
page.
Connector numbers not enclosed
by frame indicate the device incor-
porated into wiring harness.
Indicates the circuit name
to be connected. The arrow
indicates the current flow
direction.
Indicates that the diagram contin-
ues at which belongs to the
block in the same circuit.
One-directional arrow indicate
that current flows upwards.Indicates shield wire.Indicates the operating conditions
of the engine coolant switch, etc.
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, the same connector are
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).
InputOutputInput/
output
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.
