Num-
berItem Description
1 Power condition

This shows the condition when the system receives battery positive voltage (can be oper-
ated).
2 Fusible link

The double line shows that this is a fusible link.

The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tion

This shows the location of the fusible link or fuse in the fusible link or fuse box. For arrange-
ment, refer to PG section, POWER SUPPLY ROUTING.
4Fuse

The single line shows that this is a fuse.

The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating

This shows the current rating of the fusible link or fuse.
6 Connectors

This shows that connector E3 is female and connector M1 is male.

The G/R wire is located in the 1A terminal of both connectors.

Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ connec-
tor. Refer to PG section, SMJ (SUPER MULTIPLE JUNCTION).
7 Optional splice

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

The shaded circle shows that the splice is always on the vehicle.
9 Page crossing

This arrow shows that the circuit continues to an adjacent page.

The A will match with the A on the preceding or next page.
10 Common connector

The dotted lines between terminals show that these terminals are part of the same connector.
11 Option abbreviation

This shows that the circuit is optional depending on vehicle application.
12 Relay

This shows an internal representation of the relay. For details, refer to PG section, STAN-
DARDIZED RELAY.

14 Wire color

This shows a code for the color of the wire.
B = Black
W = White

Arrow indicates electric current flow, especially where the direction of standard flow (vertically
downward or horizontally from left to right) is difficult to follow.

A double arrow “ ” shows that current can flow in either direction depending on cir-
cuit operation.
20 System branch

This shows that the system branches to another system identified by cell code (section and
system).
21 Page crossing

This arrow shows that the circuit continues to another page identified by cell code.

The C will match with the C on another page within the system other than the next or preced-
ing pages.
22 Shielded line

wave line) within the system.
24 Component name

This shows the name of a component.
25 Connector number

This shows the 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 section "Main
Harness", “Harness Layout”. A coordinate grid is included for complex harnesses to aid in
locating connectors.
26 Ground (GND)

The line spliced and grounded under wire color shows that ground line is spliced at the
grounded connector.
27 Ground (GND)

This shows the ground connection. For detailed ground distribution information, refer to
"Ground Distribution" in PG section.
28 Connector views

This area shows the connector faces of the components in the wiring diagram on the page.
29 Common component

Connectors enclosed in broken line show that these connectors belong to the same compo-
nent.
30 Connector color

This shows a code for the color of the connector. For code meaning, refer to wire color codes,
Number 14 of this chart.
31Fusible link and fuse
box

This shows the arrangement of fusible link(s) and fuse(s), used for connector views of
"POWER SUPPLY ROUTING" in PG section.
The open square shows current flow in, and the shaded square shows current flow out.
32 Reference area

This shows that more information on the Super Multiple Junction (SMJ) and Joint Connectors
(J/C) exists on the PG section. Refer to "Reference Area" for details. Num-
