WIRING HARNESS
- How to Read Wiring Diagrams
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.
