* The system shown here is an EXAMPLE ONLY. It is different to the actual circuit shown in the wiring diagram section.

HOW TO READ THIS SECTION

[A] : System Title [B] : Indicates the wiring color. Wire colors are indicated by an alphabetical code. B = Black W = White BR = Brown L = Blue V = Voilet SB = Sky Blue R = Red G = Green LG = Light Green P = Pink Y = Yellow GR = Gray O = Orange Example: L – Y The first letter indicates the basic wire color and the second letter indicates the color of the stripe. L (Blue)

Y (Yellow)

GS 430/300 (EWD423F)

[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 from upper left to lower right

Female

[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.

Female

[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.

Numbered in order from upper right to lower left

HINT :

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:

Male (

).

Junction connector in this manual include a short terminal which is connected to a number of wire harnesses. Always perform inspection with the short terminal installed. (When installing the wire harnesses, the harnesses can be connected to any position within the short terminal grouping. Accordingly, in other vehicles, the same position in the short terminal may be connected to a wire harness from a different part.) Wire harness sharing the same short terminal grouping have the same color. Junction Connector

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.
