- Wiring harness repairs may not be performed again in the wrapping of the vehicle-specific wiring harness and are to be marked with yellow adhesive tape.
- These yellow wires and every location on wiring harness wrapped in yellow insulating tape indicates a previous repair.
- Crimp connections must never be repaired. Route a wire parallel to the faulty wire.
- After crimping, the crimp connectors must be heat-shrunk using the Wiring Harness Repair Set - Hot Air Blower: VAS1978/14A to prevent moisture penetration.
