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: (1) 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.
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.
