| Stable electrical performance | Low resistance copper core, ensure stable transmission of brake light and turn signal. |
1. Purchase suggestions
1. Confirm the interface type: must be 7-Pin Flat Plug (American standard), European standard requires 13-pin model.
2. Length selection:
Contracted length: common 0.5m~1m (1.5m~3m after extension).
3. Protection level: IP54 or higher (such as IP67) is recommended for outdoor use.
4. Cable quality: copper core + double insulation (anti-oxidation/wear-resistant) is preferred.
2. Precautions for safe use
Overload is prohibited: Under 12V system, the total current is ≤30A (refer to the vehicle circuit design).
Avoid excessive stretching: Exceeding the nominal stretch length may cause spiral deformation.
Regular inspection:
- Check whether the plug is oxidized or loose.
- Observe whether the outer skin is damaged (especially after off-road).
Correct wiring:
| Pin | Function |
| 1 | Left turn/brake light |
| 2 | Reversing light (optional) |
| 3 | Ground (GND) |
| 4 | Right turn/brake light |
| 5 | Tail light (Running Lights) |
| 6 | 12V power supply (battery charging) |
| 7 | Brake controller signal |
3. FAQ
Q1: Is the spiral cable more durable than ordinary trailer cable?
Yes, the spiral structure reduces bending damage and has a longer life, especially suitable for frequent plugging and unplugging scenarios.
Q2: Can it be used for European standard trailers?
No, the European standard is a 13-pin interface, which requires a special converter.
Q3: Will the conductivity be reduced after stretching?
No, the conductor cross-sectional area is fixed, and the spiral design only affects the mechanical properties.
Q4: How to repair a broken spiral cable?
It is recommended to replace the entire cable, because self-repair may cause poor contact or short circuit risks.
4. Summary
The 7-pin flat plug spiral trailer cable is an ideal solution for trailer/RV electrical connections, combining anti-entanglement, weather resistance and convenience. It is suitable for scenes with frequent movement, but attention should be paid to correct wiring and load limit.
