Apply cable base on its insulation property
Always de-energize the system before working on cables
Proper PPE duing operation
| Feature | Why It Matters |
| Correct Wire Gauge (AWG) | Ensures the harness can handle the required current without overheating or voltage drop. |
| Stranded Copper Conductor | Offers flexibility and durability—resists vibration and bending fatigue better than solid wire. |
| Heat-Resistant Insulation | Prevents insulation breakdown in hot areas like the engine bay (front harness); maintains system safety. |
| Moisture-Resistant Jacket | Protects rear harness from water ingress, especially in trunk and exterior areas. |
| Modular Design | Simplifies assembly and replacement—modules can be easily plugged or swapped during repairs. |
| Color-Coded Wires | Speeds up troubleshooting, repairs, and ensures correct installation during manufacturing. |
| Weight Optimization | Critical for EVs and fuel-efficient vehicles—reduces unnecessary wire size and excess material. |
| EMC Compliance | Ensures the vehicle meets legal and safety standards for electronic interference and emissions. |
| Fire-Retardant Materials | Improves safety by limiting flame spread in case of short circuits or system failures. |
| Testing & Quality Checks | Verifies function, safety, and durability before harnesses are installed—prevents costly recalls. |
| Shielded Signal Lines | Reduces EMI (electromagnetic interference) in sensitive signal wires (CAN, camera, radar, sensors). |
| Proper Connector Selection | Ensures secure mechanical/electrical connection and environmental sealing (IP67/IP69K rated if needed). |
| Harness Wrapping (Tapes/Sleeves) | Protects against abrasion, improves aesthetics, and organizes wires for efficient routing. |
| Routing Compatibility | Designed to fit chassis layout—avoids sharp bends, pinching, or interference with moving parts. |
| Vibration Resistance | Vital for longevity—prevents conductor fatigue and intermittent electrical faults. |
| Spare Wires or Pins | Future-proofs the system—supports upgrades or additions without redesigning the entire harness. |
