USING THIS PUBLICATION
Section numbering
The sections in this publication are ordered to match the Global Outline numbering system as found in the current Workshop
Manual. The Power and Ground distribution circuits can be found under section 414-01, 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 303-06 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
Engine control-
module (ECM) (D131)
C0331-28 NS,0.35
C0331-7 NG,0.35 C0787-1
C0331-12 UG,0.35 C0787-2
C0331-14 YG,0.35 C0787-3
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 colours are listed in a table at the end of
this section. Where wires have a predominant colour with a secondary colour tracer, the main colour is identified first, i.e. WH-BK
- white with a black tracer.
Wire length (Power and Ground Distribution only)
The wire length (in millimetres) is displayed after the colour 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 480mm from connector C2335.

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 βflyleadβ as with C503 above.
