14 Wire color
●This shows a code for the color of the wire.
B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light GreenBR = Brown
OR or O = Orange
P = Pink
PU or V (Violet) = Purple
GY or GR = Gray
SB = Sky Blue
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
15 Option description
●This shows a description of the option abbreviation used on the page.
16 Switch
●This shows that continuity exists between terminals 1 and 2 when the switch is in the A posi-
tion. Continuity exists between terminals 1 and 3 when the switch is in the B position.
17 Assembly parts
●Connector terminal in component shows that it is a harness incorporated assembly.
18 Cell code
●This identifies each page of the wiring diagram by section, system and wiring diagram page
number.
19 Current flow arrow
●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
●The line enclosed by broken line circle shows shield wire.
23Component box in
wave line
●This shows that another part of the component is also shown on another page (indicated by
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-
