Wire colors are indicated by an alphabetical code.
B = Black W = White BR = Brown
L = Blue V = Violet SB = Sky Blue
R = Red O = Orange LG = Light Green
P = Pink Y = Yellow GR = Gray

[C] : The position of the parts is the same as shown in
the wiring diagram and wire routing.

[D] : Indicates the pin number of the connector.
The numbering system is different for female
and male connectors.

Example : Numbered in order Numbered in order
from upper left to from upper right to
lower right lower left

Female Male

The numbering system for the overall wiring
diagram is the same as above

[E] : 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

[F] : 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.

Example: ,,,,,,,,,,,,,,,,,,,,,,,,,,,,tNJ3huCoan.ti3cnittdioiiscnainBtesloisdcek

[G] : Indicates related system.

[H] : Indicates the wiring harness and wiring harness
connector. The wiring harness with male
terminal is shown with arrows ( ).
Outside numerals are pin numbers.

[I] : ( ) is used to indicate different wiring and
connector, etc. when the vehicle model, engine
type, or specification is different.

[J] : Indicates a shielded cable.

[K] : Indicates and located on ground point.

[L] : The same code occuring on the next page
indicates that the wire harness is continuous.
