Connector number suffix
y
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 us e the correct circuits
appropriate to the vehicle under scrutiny.
A page is dedicated to each connector, with the information presented in a standard format. Connector
information comprises:
z Connector Number – The assigned number, prefixed 'C'.
z Description – Usually derived from the component to which the connection is made.
z Location – Used in conjunction with the photo graph 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.
z 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.
z Face View – An outline of the connector housing, viewed from the front, showing pin numbers (if
applicable).
z Part No. – The part number as it appears on the harness drawing (if applicable).
z Colour – If applicable, the colour of the connector housing is shown. NATURAL is used to describe
connectors with a clear/translucent plastic finish.
z Gender – If applicable, identifies the gend er of the connector pins (NOT the housing) as Male or
Female. Generally, connectors mating directly into a component have Female pins.
z Type – Generic connector group.
z No. of Ways – Identifies the number of cavities within the connector.

HARNESS REPAIRS
Introduction
CAUTION: The harness must be replaced when the damage is attributed to excessive current flow or
where there is evidence of over-heating.
Never attempt to repair the following:
z Any connector terminal.
z Any Media Orientated System Transport (MOST) network harnesses.
z Supplemental Restraint System (SRS) firing circuits.
z Link lead assemblies, which are unique to safety critical areas such as ABS and thermocouple circuits;
a typical example is the ABS wheel speed sensor with moulded connector.
z Any wires with a cross sectional area (CSA) greater than 6.0mm.
z Screened cables and leads.
If damage occurs to any of the above areas, an overlay harness must be used. These are available through
the normal parts ordering process.
Repair Kit
z Crimping tool.
z Wire cutter/stripper.
z Heat-shrink sleeving.
z Wire colour identification rings.
z Splice connectors.
z Pre-terminated leads (connector pins with 90mm wire 'pig tails').
z Connector housings.
z Connector pin extractor tools.
In order to carry out a repair, a suitable hot-air gun and heat resistant blanket will also be required (these can
be sourced locally).
Part Harnesses
In addition to the items included in the harness repair kits, part harnesses are also available to effect repairs
on the vehicle. These part harnesses can be viewed via 'Microcat' and are available through the normal parts
ordering process.
Repair Guidelines
The Harness Repair Kit includes an illustrated instruction booklet, however the following additional repair
guidelines must be followed:
Twisted Pairs
Twisted pairs of wires (CAN bus, ABS wiring, etc.) can be repaired as required. When repairing a twisted pair
of wires do not unwind the existing wires any more than necessary. Before completing the repair, replicate as
closely as possible the original twisting pattern on any new wiring.
Splice Connectors
It is undesirable to make more than five repair joints on the wiring to any harness connector, where more
repairs are required at the same connecto r, the harness should be replaced.
Page 8
Whenever a repair is required, the position of the splice connectors must be staggered. This keeps the bulk of
the repaired area to a minimum, ensuring all trim can be refitted correctly after the repair has been effected.
Replacement Connectors
If a connector is damaged and needs replacing, use the tools contained in the Ha rness Repair Kit to relocate
the wires into the replacement connector. Only relocate one wire at a time, ensuring it is fitted to the correct
cavity in the new connector.
Gold Connector Pins
A number of vehicle connectors are fitted with gold plated pins. Do not replace gold connector pins with tin
connector pins as this will lead to early failure of the electrical contact.
Repair Methods
CAUTION: Before commencing a repair, disconnect the vehicle battery and wait one minute to allow
the SRS and Satellite Navigation systems time to de-energise.
The following process should be used when carrying out a repair:
NOTE: Before commencing a repair, refer to the appropriate 'Service Repair Kit' table (see example in
Table 1 below) for details of the correct tools and replacement components. The 'Service Repair Kit'
table (where appropriate) can be found beneath the 'Connector Details' in the Electrical Reference
Library (ERL).
The following process should be used when carrying out a repair:
1. Using the wire cutter/stripper, cut the wire to be repaired and strip the required amount of insulation
from the wire.
2. Slide an appropriately sized heat shrink sleeve over the bare end wire for later use.
3. Remove the damaged connector pin from the connector housing using the appropriate extraction tools.
4. Select the correct connector pin, pre-terminated lead and fit the appropriate wire colour identification
rings.
5. Select the correct size of splice connector from the kit.
CAUTION: The crimping tool jaws perform two different crimps simultaneously: one crimps the
wire insulation; one crimps the bare wire. Ensure the splice connector is placed correctly in the
tool or the wire will be insufficiently crimped and a poor electrical contact may result.
6. The crimping tool contains three sets of jaws. The jaw colours correspond to the splice connector
Page 9
colour. Select the correct jaw and crimp the splice connector to the harness bare-end wire.
y
7. Using the tool, crimp the pre-terminated lead to the splice connector.
CAUTION: Place the heat resistant blanket in a suitable position to avoid heat damage to
adjacent components and trim.
CAUTION: Do not overheat the repair as degradation and subsequent failure of the connection
may result.
8. Slide the previously fitted heat shrink sleeve into position over the splice connector. Using the hot-air
gun to the manufacturer's guidelines, apply heat evenly to the heat shrink sleeve until it is tightly shrunk
around the splice connector.
9. Connect the repaired wire to the connector housing.
10. Repeat steps 1 to 9 for an
further damaged wires.

FIBRE OPTICS
General
The fibre optic system installed uses Media Oriented Systems Transport (MOST), which is a multimedia
network, optimized for automotive applications. Its design allows it to provide a low-overhead and low-cost
interface for the simplest of devices, such as microphones and speakers. More intelligent devices can
automatically determine the features and functions provided by all other devices on the network and establish
sophisticated control mechanisms without distracting the driver.
Under normal installation conditions the system is robust and failures should not oc cur. However, since the
optical fibres convey data using infra-red light, it is vital the passage of light down the fibre is unobstructed.
Obstruction of infra-red light can be caused by:
z Contamination of the fibre ends.
z Damage to the fibre ends.
z Bending, kinking or damaging the cable.
NOTE: Fibres damaged by kinking or exposure of the optical core due to abrasion must be replaced.
Handling
Take special care to avoid damage or contamination when handling or working in the vicinity of fibre optic
cables and connectors.
NOTE: Damage or contamination includes scratches to the cable ends and pollution caused by dust,
dirt, oil or moisture.
CAUTION: When handling fibre optic cables cleanliness is of paramount importance. The fibre ends
should not be touched even with clean bare hands as the natural oils deposited from the skin may
penetrate the fibre or may cause dirt to adhere to the fibre end.
System malfunctions and unnecessary warranty claims can be minimised by following these guidelines:
z After disconnection of any cables, carefully install appropriate dust caps to prote ct the ma ting faces of
the connectors from damage or contamination.
z Avoid introducing tight bends (less than 30mm radius) or kinks into the fibre optic cable during service
or repair. Tight bends or kinks could impair operation, cause immediate system failure, or future system
failure.
z Avoid excessive force, strain or stress on the fibres and connectors, especially permanent stress after
reinstallation.
