GENERAL INFORMATION - HOW TO READ THE WIRING DIAGRAMS0-3
Reading Layout Diagrams
The wiring layout diagrams give a clear and simple illustration of the connector positions and the routing of the wiring
harnesses at different points in the actual vehicle.
Indicates connector number.
The same connector number is used in the circuit diagrams, so that connector positions can be located easily.
The initial letter indicates the installation position of the connector, and the number that follows is the unique number for that
connector. In principle, the connectors are numbered in clockwise order in each layout diagrams, starting from the top left-hand side.
Example : A – 19Unique connector number (serial number)
Connector location code
A: Engine compartment D: Floor / Roof
B: Engine / Transmission E: Door
C: Instrument panel F: Tail gate
Indicates earth point.
The same earth numbers are used in the circuit
diagrams, so earth points can be located easily.
For details of earth points, refer to Section 2,
"Individual Part Installation Positions – Earth".
Indicates name of harness
Shows section covered with
corrugated tube.
The * symbol shows a standard
harness mounting point.
Indicates the external colour of the harness.
(Black, unless specified otherwise.)
R : Red
Y: Yellow
The number of connector pins and the connector colour (except
cream colour)* are indicated, so that they can be located easily.
Example : 2 – Black
*^: Typical connector colours:
Black, grey, red, blue, yellow, green, brown, etc.

otherwise)

Indicates the device to which the
connector is connected.
