PROTECT REPAIR AREA AFTER CABLE REPAIRS - AR00.19-P-0100-08C
Protect repair area by wrapping fabric tape around it.
1. Wrap fabric tape around repair area as per original condition.
Fabric tape restores the appearan ce of the repair area and provides pr otection from chafing. In parts of
vehicle subject to high levels of st ress (e.g. engine compartment) fabric tape should only be used together
with other (watertight) protective measures.

1. Expose damaged cable or plug/coupling in easily accessible position and cut off.
Separate cores in wiring harness offset by approx. 45 mm (B).
Fig. 402: Identifying Wiring Harness Offset Distance
2. Cut new section of cable to match old cable.
When cutting the line, add an allowance of approx. 50 mm (C) for loop formation (strain-relief).
3. Remove approx. 15 mm (D) of insulation at line ends.
4. Select solder cup as shown in table below.

A maximum of seven individual cables maybe inserted into each solder connection.
5. Insert the cables into the corresponding solder connections (Z) according to the total cable cross-section.
6. Ensure that solder connection (Z) is fully rotated onto cables.
Approx. 5 mm (A) of the stripped line ends should be visible.

7. Heat solder connector using a heat gun (approx. 400°C).
Start at tapered end until soldering ring has dissolved and sleeve has correctly wrapped itself around
the line.

8. Check soldered point.
The soldering ring (1) of the solder connection (Z)must no longer be visible. The covering (2) must be
resting smoothly against the cables.

9. Fit solder connection onto cable and wrap fabric tape around repaired area.
Solder connections must not be positioned directly one above the other.
