Always be sure to use the correct crimping slot for the crimping connection used. Refer to → Chapter "Crimping Pliers with Insert".

After crimping, crimp connections must be heat-shrunk using hot air gun to prevent moisture penetration.

  Heat crimp connection using hot air gun lengthwise from center outward until it is sealed completely and adhesive comes out the ends.

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 gun.
Always observe operating instructions of heat gun.
  Note
  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.
