(2) Identification of connectors differing according to different vehicle specifications
Without wiring harness connectors, the inter-device or -wiring harness connectors which vary in shape or
position on different vehicle specifications are
given the specification-dependent connector identification svm-
bol (lower case alphabet) after a serial number.
For detailed information on this specification-dependent symbol, refer to Item (8) under “HOW
TO READ
CIRCUIT DIAGRAMS”.
(3) Indication of standard mounting positions of harnesses
The standard mounting positions of harnesses are shown with the mark * in wiring harness configuration
diagrams.
(4) Indication of ground point
The position of ground points are shown in wiring harness configuration diagrams. For detailed information on
the ground portion, refer to ELECTRICAL SYSTEM PARTS LOCATION (Grounding).

HOW TO READ CIRCUIT DIAGRAMS
The circuit diagrams are functionally separated.
(1) Indication of circuit connected to another circuit
When the circuit in a circuit diagram connected to another circuit in a different diagram, the page number of that
different diagram is indicated so that it can be referred to.
(2) Indication of device connections
The circuit diagram shows whether a device harness connection is one with an attached cable or is a direct
connection type.
(3) Indication of connectors in circuit diagrams
A connector in a circuit diagram is shown in a frame and is assigned a connector symbol. This symbol
corresponds to the symbol in a wiring harness configuration diagram so that the connector location can be
known easily. An intermediate connector has its female side only shown as a rule. However both of the male
and female sides are shown when they differ in wiring color.
Refer to Item (2)
If a frame showing a connector touches the
?. it indicates that the de-
a direct connec- symbol of a device
vice
harness connectlon IS
tion type.
Refer to Items (2) and (3).
The frame shows the connector is not touch- ing the symbol of a device, and indicates that
the device harness connection is one with an
attached cable.
Indicates direct grounding from
the device to the bodv.

nectar. On a circuit connected to another circuit the
names of devices to which the circuit is con-
nected and pages on which diagrams of such
another circuit appear are indicated.

(4) Indication of fuses, fusible links and centralized relays
The fuses and fusible links in a circuit diagram are indicated by a wave symbol (-) and a double wave symbol
(~1, respectively. At a centralized junction, the fuses are given fuse numbers and centralized relays are given
connector symbols.
Example of centralized junction symbol: A - 01 x
Centralized junction indication symbol
Connector’s unique number (serial number)
Connector symbol
(5) Indication of ground point
The ground point in a circuit diagram is marked by a ground symbol, making it possible for you to refer to a
wiring harness configuration diagram and to ELECTRICAL SYSTEM PARTS LOCATION (Grounding).
(6) Indication of wires
In a circuit diagram, the wire diameter and wire color are shown for each wire. If there are several wires
of the same color in a connector, their wire color indication symbols should be such symbols as “I and
“2 for identification.
On connectors like this one given a central-
to CENTRALIZED JUNCTION for connector

in color (RL), so they are given identification
symbols *I and *2 in order to distinguish
them. 1 ST6 Revision
