: System Title
: 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.
: Indicates the connector to be connected to a part (the
numeral indicates the pin No.)
Explanation of pin use.
The pins shown are only for the highest grade, or only
include those in the specification.
: Connector Color
Connectors not indicated are milky white in color.
: ( ) is used to indicate different wiring and connector,
etc. when the vehicle model, engine type, or
specification is different.
: Indicates related system.
: Indicates the wiring harness and wiring harness
connector. The wiring harness with male terminal is
shown with arrows ( ).
Outside numerals are pin numbers.
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.
: Represents a part (all parts are shown in sky blue). The
code is the same as the code used in parts position.
: 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 (different junction blocks are shaded differently for
further clarification).
3B indicates
that it is inside
Junction Block
No. 3.
Example:
: Indicates the wiring color.
Wire colors are indicated by an alphabetical code.
B = Black L = Blue R = Red
BR = Brown LG = Light Green V = Violet
G = Green O = Orange W = White
GR = Gray P = Pink Y = Yellow
The first letter indicates the basic wire color and the
second letter indicates the color of the stripe.
Example: L – Y
(Blue) (Yellow)
: Indicates a wiring Splice Point (Codes are “E” for the
Engine Room, “I” for the Instrument Panel, and “B” for
the Body).
Example:
The Location of Splice Point I 5 is indicated by the
shaded section.
: Page No.
: Indicates a shielded cable.
: 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.
: 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
: When 2 parts both use one connector in common, the
parts connector name used in the wire routing section
is shown in square brackets [ ].
