intermediate wire section
Note
For the repair use repair wires with a cross section of 0.35
mm2 through 6.0-mm2.
Procedure

20 cm on both sides of the repair point.
Caution
Risk of damaging the electrical wires.
Expose wrapped wiring harnesses carefully.
- If necessary, removing the wiring harness wrapping using a
knife.
- Route the yellow repair wire next to the damaged wiring
harness and cut the repair wire to the required length using the
Wiring Harness Repair Set - Wire Strippers -VAS1978/3-.
- Cut damaged wire section from the vehicle-specific single
wire.
- Adjust the sliding stop in the Wiring Harness Repair Set -
Wire Strippers -VAS1978/3- pliers jaws to 6 to 7 mm for the wire
to be stripped.
- Insert the vehicle-specific single wire end from the front
into the pliers jaws as far as the stop and squeeze the pliers
together completely.
- Open pliers again and remove the stripped wire end.
- Repeat the procedure on the other end of the
vehicle-specific individual wire.
- For the repair, use two suitable crimp connectors from the
Wiring Harness Repair Set -VAS1978B-.
Note
- Always be sure to use the corresponding crimp connector and
the correct crimping slot for the crimping connection used.
Refer to
→ Chapter "Crimping Pliers with Insert".
- Do not crimp wire insulation.
- Use the Wiring Harness Repair - Crimping Plier - Base Tool
-VAS1978/1-2- to press the crimp connector.

- Slide the crimp connector onto the vehicle-specific single
wire at one side and onto repair wire at the other side.
- Crimp the crimp connection at both wire ends using crimp
pliers.
- Repeat this procedure on the other wire ends.
Note
Do not crimp wire insulation.
After crimping, crimp connections must be heat-shrunk using
hot air gun to prevent moisture penetration.
- Insert the Wiring Harness Repair - Blower - Shrink Element
-VAS1978/15A- on the Wiring Harness Repair Set - Hot Air Blower
-VAS1978/14A-.
Caution
Risk of damaging surrounding components.
- When heat-shrinking crimp connections, be careful
not to damage any other wiring, plastic parts or
insulating material with the hot nozzle of the hot air
blower.
- Always observe operating instructions of heat gun.
- Heat crimp connection using the hot air blower lengthwise
from center outward until it is sealed completely and adhesive
comes out the ends.
- This is how the completed repair location with the inserted
wire and two crimp connectors should look.
Note
- Make sure that crimp connections do not lie directly next to
each other when several wires need to be repaired. Arrange the
crimp connectors at a slight offset so that the circumference of
the wiring harness does not become too large.
- If the repair point was previous taped, this point must be
taped again with yellow insulating tape after repairs.
- Secure the repaired wiring harness if necessary with a cable
tie to prevent flapping noises while driving.
