HOW TO READ WIRING DIAGRAMS

Connector symbols

INFOID:0000000003938043

Most of connector symbols in wiring diagrams are shown from the terminal side.
• Connector symbols shown from the terminal side are enclosed by

a single line and followed by the direction mark.

• Connector symbols shown from the harness side are enclosed by

a double line and followed by the direction mark.

• Certain systems and components, especially those related to

OBD, may use a new style slide-locking type harness connector.
For description and how to disconnect, refer to PG section,
“Description”, “HARNESS CONNECTOR”.

• Male and female terminals

Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

Description

INFOID:0000000003938045

SWITCH POSITIONS 

Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.
A vehicle is in the “normal” condition when:

Number

Item

Description

1

Power supply

• This means the power supply of fusible link or fuse.

2

Fusible link

• “X” means the fusible link.

3

Number of fusible link/
fuse

• This means the number of fusible link or fuse location.

4

Fuse

• “/” means the fuse.

5

Current rating of fus-
ible link/fuse

• This means the current rating of the fusible link or fuse.

6

Optional splice

• The open circle shows that the splice is optional depending on vehicle application.

7

Connector number

• The letter shows which harness the connector is located in.
• Example “M”: main harness. For detail and to locate the connector, refer to 

PG-64, "Elec-

trical Units Location"

, 

PG-38, "Harness Layout"

.

8

Splice

• The shaded circle “

” means the splice.

9

Page crossing

• This circuit continues to an adjacent page.

10

Option abbreviation

• This means the vehicle specifications which layouts the circuit between “

”.

11

Relay

• This shows an internal representation of the relay.

12

Option description

• This shows a description of the option abbreviation used on the page.

13

Switch

• This shows that continuity exists between terminals 1 and 2 when the switch is in the A 

position. Continuity exists between terminals 1 and 3 when the switch is in the B position.

14

Circuit (Wiring)

• This means the wiring.

15

System branch

• This shows that the circuit is branched to other systems.

16

Shielded line

• The line enclosed by broken line circle shows shield wire.

17

Component name

• This shows the name of a component.

18
