WIRING HARNESS
Wiring: Precautions for the repair
88A
I - SAFETY
1 - Potentially dangerous components
Do not leave any unused +12V connectors exposed to
the air without any protection (see Connector: Sea-
ling and locking) (Technical Note 6015A, 88A, Wi-
ring).
Check that there is no contact between the wiring and
the fuel and brake pipes.
Avoid mounting the wiring in areas with a temperature
above 100˚C.
2 - Advice to be followed before any operation
Before carrying out any work on the wiring, disconnect
the battery.
3 - Instructions to be followed during the operation
To prevent the wiring from being damaged, check that
the surrounding area is not mechanically harmful (e.g.:
door windows, sharp corners, burrs, studs, etc.).
The wiring should be at least 30 mm away from any
moving components (belt, pulley, steering column,
etc.).
Depending on the surrounding area, check that the
unused connectors respect the necessary sealing
constraints (see Connector: Sealing and locking)
(Technical Note 6015A, 88A, Wiring).
All of the connections (connectors) used in the engine
compartment are sealed; do not remove the seal from
around the connectors.II - GENERAL RECOMMENDATIONS
Do not connect an earth to a stud with insulating pro-
tection (paint,etc.).
Do not use more than two earth terminals on the same
point.
Do not use power earths on the same point as electro-
nic earths.
To prevent water flowing into the connectors, make a
low point just on the wiring routing (just before the con-
nector).
For connections between fixed and mobile compo-
nents, secure the wiring on the fixed part.
Overlapping of the battery feed wires (positive and ne-
gative) causes disruption; they must be secured sepa-
rately.
Wiring mountings:
- use plastic clips, ensuring that the colour coding is
respected,
-do not use steel clips that are not protected with rub-
ber,
- keep the clips integrated into the wiring during a re-
placement operation,
- do not leave steering wheel wires without protection.
Check that:
- the shunts are correctly secured,
- the connectors are correctly housed and locked.
Wiring routing:
- when it is visible it must be aesthetically pleasing, and
resemble the routing marked during removal,
- prohibit wiring routing in grooves and overlaps (risk of
wear through friction),
- prohibit mounting several wires on the same clip,
- do not lock the connectors or wiring in areas that are
sensitive to drilling (number plate etc.). WARNING
To prevent damaging the connectors, consult the
disconnection procedure (see Connector: Discon-
nection and reconnection) (Technical Note
6015A, 88A, Wiring).
WARNING
To prevent any risk of noise, premature wear, short
circuits, etc. after the refitting operation, mark the
wiring routing and how to connect the connectors.
WARNING
To prevent any damage during the removal opera-
tion, check that the wiring is free from its mountings
(retaining clip, plastic clip, adhesive tape, connec-
tor, etc.).
