Introduction
Introduction
Health and safety
Always follow health and safety guidelines.
Using this information
The information provided is for use only by competent, qualified auto-electricians. Good product knowledge is assumed, as well as the ability to access and use recommended test equipment and other reference material provided.
Test equipment and other reference material
The information should be used in conjunction with the recommended test equipment. Other reference material includes: Technical Service Bulletins (TSB).
The Electrical Reference Library (ERL) may also prove useful since it provides detailed connector information.
Battery disconnection and reconnection
It is imperative that any information relating to battery disconnection and reconnection is followed.
Fault Diagnosis
Always use the recommended test equipment for correct and reliable fault diagnosis.
Harness Repair
Repairs should only be undertaken for connectors where a Service Repair Kit is available; refer to the appropriate Electrical Reference Library (ERL).
NOTE: Fibre Optic circuits cannot be repaired.

Section numbering
The sections are ordered to match the Global Outline numbering system. The Power and Ground distribution circuits can be found under section, BATTERY, MOUNTING AND CABLES.
NOTE: Where circuit diagrams show more than one sub-system, the circuit will be located in the section that carries the first-named sub-system, for example: Starting and Charging will be located under section Starting System, since 'Starting' is the first-named sub-system.
Circuit sheet numbering
The figures in brackets to the left of the page number indicate a circuit sheet number and the total number of sheets per circuit, for example (01/05) represents sheet 1 of 5.
Understanding the circuit diagrams
Components
After each component description, a translation code is displayed in brackets, for example: Starter relay (R102), Engine control-module (ECM)(D131). The codes can be ignored.
NOTE: A dotted outline indicates that the component identified is not shown in its entirety.
Connectors
Connectors and header joints are identified by their corresponding connector number with a numbered suffix to indicate the pin-out detail of the wire, i.e. C0292-1 identifies connector 292, pin number 1. Wire insulation colors are listed in a table at the end of this section. Where wires have a predominant color with a secondary color tracer, the main color is identified first, i.e. LGS - light green with a slate tracer.
Splices
The splices (and where appropriate, the header) circuit pages show the full interconnectivity of components and systems.
NOTE: The splice information shown on individual system circuits is not complete. Always refer to the splices circuit pages for complete information for each splice.
Wire length (Splices, Power and Ground Distribution only)
The wire length (in millimeters) is displayed after the color and cross sectional area; for example, SR,0.35,480. In this example, the figure, 480 indicates the approximate position of the harness splice is 480 mm from connector C2335.
Wire Types
Multicore wires are identified by the prefix M suffixed by three or four other letters, for example MCGA, MAPN. The suffix precisely defines the parameters that comprise the specification of the wire type. The specification is defined during the design process of an electrical system, therefore it is imperative that the correct specification is maintained to ensure the correct operating characteristics and continued functionality for a given system.
Line Types
Crossed wires as illustrated above show an example of how a twisted pair of wires may be represented on the circuits.
The arrows illustrated above show an example of the page break symbols, identifying that the circuit continues at the corresponding letter on the sheet number indicated.
The cup and ball symbol represents the male and female halves of connector. Most connectors plug directly into a component but some are wired directly to the component using a flylead as with C503 above.
Ground points
Ground points are identified with an eyelet symbol and a connector number, except where components are grounded through its fixings, when only the eyelet is shown.
