Connector number suffix
To provide more accurate connector information, in some instances, a suffix has been added to the connector that identifies the vehicle harness derivative; refer to the Connector number suffix table below.
NOTE: The suffix does not always appear on the circuit. Take care to use the correct circuits appropriate to the vehicle under scrutiny.
Connector number suffix table
Connector details
A page is dedicated to each connector, with the information presented in a standard format. Connector information comprises:
- Connector Number - The assigned number, prefixed 'C'.
- Description - Usually derived from the component to which the connection is made.
- Location - Used in conjunction with the photograph to determine the location of the connector.
NOTE: References to the LH or RH side given in this document are made when viewing the vehicle from the rear.
- Photograph - Shows the location of the subject connector. In most cases the photograph will indicate the amount of trim removal necessary to reveal the connector. For convenience, some photographs identify more than one connector.
- Face View - An outline of the connector housing, viewed from the front, showing pin numbers (if applicable).
- Part No. - The part number as it appears on the harness drawing (if applicable).
- Colour - If applicable, the colour of the connector housing is shown. NATURAL is used to describe connectors with a clear/translucent plastic finish.
- Gender - If applicable, identifies the gender of the connector pins (NOT the housing) as Male or Female. Generally, connectors mating directly into a component have Female pins.
- Type - Generic connector group.
- No. of Ways - Identifies the number of cavities within the connector.
- Service Repair Kits (where applicable) - Gives details of all harness repair kits applicable to the connector. If a connector has different types of cavity, more than one service repair kit will be required.
- Wire Chart (Pin-out table) - A six column table, giving details of each wire within the connector:
1. Cav: The connector pin (cavity) number.
NOTE: Wires may not be fitted to all cavities.
2. Terminal: Part number of the pin.
NOTE: Some wires do not have terminals, for example: antennae.
3. CSA: The cross sectional area of the wire in mm (squared).
4. Col: The colour of wire populating the connector pin.
5. Cct: Identifies the model or option which uses the wire. 'ALL' means applicable to all models in the range fitted with the feature or system in question. In instances where different models, features or systems require different colour wires to be fitted in a cavity, each instance of the cavity is included in the pin-out table.
6. Destn: The destination of the wire.
