[A]
: System Title
[B] : Indicates a Relay Block. No shading is used and
only the Relay Block No. is shown to distinguish it
from the J/B
Example: Indicates Relay Block No.1
[C] : ( ) is used to indicate different wiring and
connector, etc. when the vehicle model, engine
type, or specification is different.
[D] : Indicates related system.
[E] : Indicates the wiring harness and wiring harness
connector. The wiring harness with male terminal is
shown with arrows (
).
Outside numerals are pin numbers.
Female Male ( )
The first letter of the code for each wiring harness
and wiring harness connector(s) indicates the
component’s location, e.g, ”E” for the Engine
Compartment, ”I” for the Instrument Panel and
Surrounding area, and ”B” for the Body and
Surrounding area.
When more than one code has the first and second
letters in common, followed by numbers (e.g, IH1,
IH2), this indicates the same type of wiring harness
and wiring harness connector.
[F] : Represents a part (all parts are shown in sky blue).
The code is the same as the code used in parts
position.
[G] : Junction Block (The number in the circle is the J/B
No. and the connector code is shown beside it).
Junction Blocks are shaded to clearly separate
them from other parts.
3C indicates that
it is inside
Junction Block
No.3
Example:
[H] : Indicates the wiring color.
Wire colors are indicated by an alphabetical code.
B = Black W = White BR = Brown
L = Blue V = Violet SB = Sky Blue
R = Red G = Green LG = Light Green
P = Pink Y = Yellow GR = Gray
O = Orange
The first letter indicates the basic wire color and the
second letter indicates the color of the stripe.
Example: L – Y
L
(Blue) Y
(Yellow)
[I] : Indicates a wiring Splice Point (Codes are ”E” for the
Engine Room, ”I” for the Instrument Panel, and ”B”
for the Body).
The Location of splice Point I 5 is indicated by the
shaded section.
[J] : Indicates a shielded cable.
[K]: Indicates the pin number of the connector.
The numbering system is different for female and
male connectors.
Example: Numbered in order
from upper left to
lower right Numbered in order
from upper right to
lower left
Female Male
[L]: Indicates a ground point.
The first letter of the code for each ground point(s)
indicates the component’s location, e.g, ”E” for the
Engine Compartment, ”I” for the Instrument Panel
and Surrounding area, and ”B” for the Body and
Surrounding area.
