ELECTRICAL INSTALLATION GENERAL OUTLINES
PRESENTATION:
The electrical system operations are composed of:
- A main wiring diagram.
- A circuit diagram.
- Lists of parts,
harnesses,
earth connections,
connectors between harnesses.
- A fuse table.
A lamp chart.
- Various circuit and wiring diagrams for special functions or optional equipment.

UTILISATION:
The wiring diagram indicates the location of the components, harnesses, earth connections and connectors
on the vehicle.
The circuit diagram presents the electrical circuits in a functional way.
- The components symbols in the circuit diagra*m are those shown on the symbol key (see pages 2 and 31.
- Several symbols can be used for a component and the item can be shownC.exploded on different lines
according to the functions.
- Switches are shown at rest, with vehicle stationary, and the doors closed.
- The switches must be moved from right to left.
- The position of a relay coil, generally to the left of the contact switch, is not compulsorily so.
- In cases where the selector switch is complex, the contact movements are shown in the manner to be
considered the most comprehensible.
- The electronic control units are not shown in detail.
Parts list: the parts are in the alphabetical order, and numbered.
The number of the item remains the same on all the diagrams provided the functron has not changed. The
parts list enables any item to be located on the wiring diagram (by means of letters and figures), and on the
circuit diagram (with a vertical line No). The identification of the connector and the ref. letter of the harness
attached to the part are also included in the parts list.
List of harnesses: it gives the position of electrical harnesses on the wiring diagram and the location of each
lead of this harness on the circuit diagram (capital letter in the middle of the wire).
List of earth connections: it indicates the location of the earth connections and the wires or connectors and
the connecting harnesses (letter CC m )), followed by a number).
List of harness inter connections : it indicates,
- the reference of the harness concerned,
- the type of end fittings: I, metal contact or connecting pin,
U, clip or socket,
- the colour of the wire insulator and the marking or sleeve colour code,
- the junction connector: number of channels, colour and channel involved,
- the location of this connector on the wiring diagram,
- the location of each channel of the connector on the circuit diagram.
The harnesses are described in alphabetic order.
