Detail Steps/Work Items Key Items/References
(1)
- Attach a cable tie at each end of the netting.
- Put a tape on each end of the
netting.
The tape will prevent splitting of the netting.
Netting, tape, and cable ties are included in Kit E4A-95-100-000 No.
[10].
Refer to Fig. 71-63.
(2) Connect the pigtail of the FPS connector and tighten the screw of the FMU.
M5 screw.
Refer to Fig. 71-64.

e) FPS connection with Engine Harness E4A(B)-95-000-000 Rev. AG.1 or higher
Detail Steps/Work Items Key Items/References
(1)
If not already attached to the white cable of
the FPS AEP-00284-901, apply additional caving protection [15] to the white cable of
FPS.
(2)
For each sensor cable, approx. 150 mm of caving protection [15] is necessary. Attach a
cable tie [14] at each cable to prevent caving protection from becoming loose.
Refer to Fig. 71 - 92b.
(3)
Make sure that the connectors of FPS are
correctly locked. The red dot must be clearly and completely visible.
Refer to Fig. 71 - 92c.
For examples of incorrect locking, yellow dot not visible, or only partially
visible, refer to Fig. 71 - 92d, Fig. 71 - 92e and Fig. 71 - 92f. (The color of the dot is not relevant, pictures give general information).
(4) Fold back the sensor cable FPS and attach it
with two cable ties [05] at the branch of FMU.
Green marked area for folding back.
Refer to Fig. 71 - 92g.
With engine harness AG.1 and higher no extra pigtail for FPS is necessary.

The Note after Step 1 is amended to read:
It is recommended to cut the cable branch behind the solder sleeve of the pigtail.
When you use the repair kit E4A-95-R23-000 to change from OPS version
E4A-52-100-801 to AEP-00284-901, cut the single wires as near to the connector as possible. Cut the existing ring terminal at the end of the pigtail
as near to the ring terminal as possible (refer to Fig.71-94a). Continue with Step (9).

The following note is added after Step (10):
If the repair kit E4A-95-R23-000 is used, the other end of the solder sleeve (silver braid) is already connected with the connector housing.
The Step (11) is amended to read:
(11) Cut the repair kit to the necessary length.
The length of the repair kit must not be
more than 300 mm of the initial cable.
For repair kit E4A-95-R23-000 used for OPS cable, the length should not be
more than 200 mm.
(13a)
In case of repair kit E4A-95-R23-000 and change from OPS version E4A-52-100-802 to
AEP-00284-901, use an additional in-line crimp to connect the reamed pigtail from the
engine harness to the pigtail of the repair kit.
Handling / crimping of the in-line crimp follows the same procedure as
described for the single wires in the following steps. No additional
instructions required.
(15)
Seal the splice crimps: - Put the isolation sleeve over each
splice crimp.
- Apply heat on the isolation sleeve until the sleeve seals the splice crimp.
Use a hot air gun (300°C – 350°C).
Refer to Fig. 71 - 103.
Refer to Fig. 71-104a for additional in-
line crimp to connect the pigtail of the engine harness and repair kit, if
necessary.

(19)
For fuel pressure sensor (FPS) branch only:
Install the shielding E4A-95-100-000 for the engine harness.
- Put a netting over the FPS and FPS cable.
- Attach a cable tie on each netting end. - Apply a tape to each netting end.
Netting length 180 mm. Use the cable ties from the repair kit.
This will prevent splitting of the netting.
Refer to Fig. 71-106 and Fig. 71-107.
