4.1.4 Unused Connectors
The harnesses may have a number of unused
connectors, which are dedicated to other features
and options, for example heated seats, but are
not
always present depending on level of harness
fitted. Ford
do not
recommend the use of these
connectors for any other purpose than that
intended by design.
4.1.5 Grounding
Drill point screws are not to be used for any ground
attachments:
•
Do not ground to moving structures, for
example: doors, deck lids, lift gates, as the
ground return path through the hinges is not
reliable.
•
Do not place more than 2 eyelet terminals under
a single ground screw.
•
Do not place electrical component attachments
or ground screws adjacent to vehicle fuel tanks
or fuel lines.
4.1.6 Prevention of Squeaks and
Rattles
Wiring should be positively retained every 150 to
250mm. All connectors should be positively
retained. Use tapes which do not squeak against
metal or plastic.
4.1.7 Water Leakage Prevention
Make sure that drip loops are provided to prevent
water leakage into the vehicle interior, passenger
and cargo compartments, using wiring assemblies
that pass from outside into the vehicle interior. The
drip loop is a section of wiring that is deliberately
formed and routed BELOW the point of entry into
the vehicle, so that gravity assists in forming water
droplets that escape from the lowest part of the
wiring.
Wiring from door to passenger compartment,
should be made such that the door entry point is
below the passenger compartment entry point,
which creates a type of drip loop.
4.1.8 Wiring Splicing Procedures
TYCO-RAYCHEM crimp splices
E131081
Ford Motor Company strongly advises against the
use of wire splicing due to the variable and
unpredictable nature of making robust, durable
and reliable connections. However, if it is deemed
that a wire splice is absolutely unavoidable, it must
be made with
DuraSeal Heat-Shrinkable,
Environmentally Sealed, Nylon-Insulated
Crimp Splices
(manufactured by
TYCO-RAYCHEM). For example the D406 series.
As a further process to improve the splice integrity,
the splice should be further sealed with a suitable
heat shrink tubing. See Figure E131081.
