HOW TO READ CONFIGURATION DIAGRAMS
The wiring harness diagrams clearly show the connector locations and harness routings at each site
on actual vehicles.
Denotes connector No.
The same connector No. is used throughout the circuit diagrams to facilitate
connector location searches.
The first alphabetical symbol indicates the location site of the connector
and a number that follows is the unique number. Numbers are assigned to
parts in clockwise order on the diagram.
A-43
Example: A-12
Number specific to connector (serial number)
Connector location site symbol
A: Engine compartment
B: Engine and transmission
assembly
C: Dash panel
Denotes earth point.
Same earth number is used throughout circuit
diagrams to facilitate search of earth point. Refer
to SINGLE PART INSTALLATION POSITION -
EARTH MOUNTING LOCATIONS for details of
earth points.
Indicates the device to which the
connector is to be connected.

The number of connector pins and the
connector colour (except milk white)* are
shown for ease of retrieval.

Denotes the colour of corrugated
tube or vinyl tube. (If not specified,
it is black.)
R: Red

HOW TO READ CIRCUIT DIAGRAMS
The circuit of each system from fuse (or fusible link) to earth is shown. The power supply is shown
at the top and the earth at the bottom to facilitate understanding of the current flow.
Indicates the power supply in the control
unit. If no voltage is displayed, this
indicates SYSTEM voltage.
Indicates power take out.
Indicates connector No. The same
No. as in the wiring harness diagram
is used.
Connector numbers enclosed by
frame are indicated with the
connector symbols at the lower part
of the page.
Connector numbers not enclosed by
a frame indicate components which
are integrated with the harness.
Indicates harness junction point No. for
another system. It corresponds to the
junction point No. indicated on the
destination system circuit diagram.
Indicates the circuit name to be
connected. The arrow indicates the
current flow direction.
An “X” at the end of a connector No.
indicatesthattheconnectorisconnected
to a centralized junction that is shown
in the section “CENTRALIZED JUNC-
TION”.
Indicates the operating condi-
tions of the engine coolant
temperature switch, etc.
Indicates the connector symbol.
Connectors in the circuit diagram are
indicated in numerical order.
Indicates shield wire.
Indicates that terminal is connected via
a plate in the relay box.
Each circuit diagram consists of
block(s). The blocks are divided by
page number.
Indicates that the diagram continues
at
A
which belongs to the
block
in the same circuit.
2
Indicate that the current flows
from down to up. Bi-directional
arrows indicate
that
the
direction of
current flow
changeswhencommunication
is in progress.

to/from
control unit (current flow direction).
Input Output
Input/
output
In case two or more connectors are
connected to the same device, markings
indicating the same connectors are
connected by a broken line.
Indicates current flow downward or
upward as controlled by the control unit.
Indicates harness junction where wire
diameter or colour changes.
Indicates intersections at
which the lead wire are not
connected.
Indicates intersections at
which the lead wires are
connected.
Indicates representative vehicle body
earth point. (Same No. as that of earth
point in wiring harness diagram and
installation locations of individual parts.)
Indicates that the terminal is a spare
one if the device (sensors in this
case) is not provided.
Indicates terminal No.
Indicates that the diagram comes from
A
which belongs to the
block
in the same circuit.
1
A broken line indicates that these
connectors are the same intermedi-
ate connectors.
Indicates a wiring connector which is inside
the equipment and which is not shown in
the wiring harness configuration diagram.
Example C-15-2
Indicatestheconnectornumber
shown in the wiring harness
configuration diagram.
Indicates a connector
which is inside the
equipment, numbered
in order starting from 1.
