Wire Break with Single Repair Point

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.

In the event the repair point was previous taped, this point must be taped anew with yellow insulating tape after repairs.

Secure the repaired wiring harness if necessary with a cable tie to prevent flapping noises while driving.
