- Regular Inspection: Periodically inspect the wiring harness for any signs of wear, fraying, cuts, or loose connections. Address any issues promptly to prevent further damage.
- Cleaning: Keep the harness clean and free from dirt, dust, and moisture. Use a dry, soft cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Avoid Stress: Do not pull or yank on the cables. Ensure they are not subjected to excessive bending, tension, or sharp angles that could damage the internal wires.
- Environmental Protection: Protect the wiring from extreme temperatures, direct sunlight, and prolonged exposure to harsh weather conditions, which can degrade the cable insulation.
