B A : System Title J : Indicates the wiring color. Wire colors are indicated by an alphabetical code. B : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown distinguish it from the J/B. B = Black BR = Brown G = Green GR = Gray L = Blue LG = Light Green O = Orange P = Pink R = Red V = Violet W = White Y = Yellow Example: 1 Indicates Relay Block No. 1. C : Indicates the connector to be connected to a part (the numeral indicates the pin No.) Explanation of pin use. The first letter indicates the basic wire color and the second letter indicates the color of the stripe. Example: L − Y K :
Indicates a wiring Splice Point (Codes are “E” for the Engine Room, “I” for the Instrument Panel, and “B” for the Body). (blue) (yellow) The pins shown are only for the highest grade, or only include those in the specification. Example: D : Connector Color Connectors not indicated are milky white in color: E : ( ) is used to indicate different wiring and connector, etc. when the vehicle model, engine type, or specification is different. The Location of Splice Point I 5 is indicated by the shaded section. F : Indicates related system. L : Page No. G : Indicates the wiring harness and wiring harness connector. The wiring harness with male terminal is shown with arrows ( ). v v M :
Indicates a shielded cable. N : Indicates a ground point. The first letter of the code for each wiring harness and wiring harness connector(s) indicates thecomponent’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. 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. O : Indicates the pin number of the connector. The numbering system is different for female and male connectors.
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. lower right lower left H : Represents a part (all parts are shown in sky blue). The code is the same as the code used in parts position. I : 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 then from other parts. Example: P : When 2 parts both use one connector in common, the parts connector name used in the wire routing section is shown in square brackets [ ]. 3B indicates that it is inside Junction Block No. 3. 5
