Seal the crimp connector (1) using a hot-air gun.

Repair note: Make sure that the crimp connectors are not directly next to each other when several cables are to be repaired. To prevent the circumference of the cable from becoming too large, arrange the crimp connectors slightly offset.

If the repair area was previously wrapped, this area must be re-wrapped with yellow insulating tape after the repair.

If necessary, secure the repaired wiring harness with a cable tie to prevent rattling noises during driving.
