Description
Number Item Description
V1Power conditionlThis shows the condition when the system receives battery positive voltage (can
be operated).
V2Fusible link
lThe double line shows that this is a fusible link.
lThe open circle shows current flow in, and the shaded circle shows current flow
out.
V3Fusible link/fuse locationlThis shows the location of the fusible link or fuse in the fusible link or fuse box.
For arrangement, refer to EL section (``POWER SUPPLY ROUTING'').
V4Fuse
lThe single line shows that this is a fuse.
lThe open circle shows current flow in, and the shaded circle shows current flow
out.
V5Current ratinglThis shows the current rating of the fusible link or fuse.
V6Connectors
lThis shows that connectorE3is female and connectorM1is male.
lThe G/R wire is located in the 1A terminal of both connectors.
lTerminal number with an alphabet (1A, 5B, etc.) indicates that the connector is
SMJ connector. Refer to GI-17.
V7Optional splicelThe open circle shows that the splice is optional depending on vehicle application.
V8SplicelThe shaded circle shows that the splice is always on the vehicle.
V9Page crossinglThis arrow shows that the circuit continues to an adjacent page.
lThe A will match with the A on the preceding or next page.
V10Common connectorlThe dotted lines between terminals show that these terminals are part of the same
connector.
V11Option abbreviationlThis shows that the circuit is optional depending on vehicle application.
V12RelaylThis shows an internal representation of the relay. For details, refer to EL section
(``STANDARDIZED RELAY'').
V13ConnectorslThis shows that the connector is connected to the body or a terminal with bolt or
nut.
V14Wire color
lThis shows a code for the color of the wire.
B = Black BR = Brown
W = White OR = Orange
R = Red P = Pink
G = Green PU = Purple
L = Blue GY = Gray
Y = Yellow SB = Sky Blue
LG = Light Green CH = Dark Brown
DG = Dark Green
When the wire color is striped, the base color is given first, followed by the stripe
color as shown below:
Example: L/W = Blue with White Stripe
V15Option descriptionlThis shows a description of the option abbreviation used on the page.
V16Switch
lThis 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.
V17Assembly partslConnector terminal in component shows that it is a harness incorporated assem-
bly.
V18Cell codelThis identifies each page of the wiring diagram by section, system and wiring dia-
gram page number.

Number Item Description
V19Current flow arrow
lArrow indicates electric current flow, especially where the direction of standard
flow (vertically downward or horizontally from left to right) is difficult to follow.
lA double arrow ``bÐ
c'' shows that current can flow in either direction depending
on circuit operation.
V20System branchlThis shows that the system branches to another system identified by cell code
(section and system).
V21Page crossing
lThis arrow shows that the circuit continues to another page identified by cell code.
lThe C will match with the C on another page within the system other than the next
or preceding pages.
V22Shielded linelThe line enclosed by broken line circle shows shield wire.
V23Component box in wave
linelThis shows that another part of the component is also shown on another page
(indicated by wave line) within the system.
V24Component namelThis shows the name of a component.
V25Connector number
lThis shows the connector number.
lThe letter shows which harness the connector is located in.
Example:M: main harness. For detail and to locate the connector, refer to EL sec-
tion (``Main Harness'', ``HARNESS LAYOUT''). A coordinate grid is included for
complex harnesses to aid in locating connectors.
V26Ground (GND)lThe line spliced and grounded under wire color shows that ground line is spliced
at the grounded connector.
V27Ground (GND)lThis shows the ground connection.
V28Connector viewslThis area shows the connector faces of the components in the wiring diagram on
the page.
V29Common componentlConnectors enclosed in broken line show that these connectors belong to the
same component.
V30Connector colorlThis shows a code for the color of the connector. For code meaning, refer to wire
color codes, Number
V14of this chart.
V31Fusible link and fuse box
lThis shows the arrangement of fusible link(s) and fuse(s), used for connector
views of ``POWER SUPPLY ROUTING'' in EL section.
The open square shows current flow in, and the shaded square shows current
flow out.
V32Reference arealThis shows that more information on the Super Multiple Junction (SMJ) and Joint
Connectors (J/C) exists on the foldout page. Refer to GI-17 for details.

CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from
the terminal side.
lConnector symbols shown from the terminal side are
enclosed by a single line and followed by the direction mark
.
lConnector symbols shown from the harness side are
enclosed by a double line and followed by the direction mark
.
lMale and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.
