Tips & Tricks
- Check trailer wiring and plugs before installing the adaptor. If there are faults or corrosion, fix these first.
- Use weather-resistant connectors, especially for coastal or off-road use.
- Test all trailer lights after installation to confirm correct operation and that no warning lights appear on your vehicle’s dashboard.
- Mount the adaptor in a dry, secure location near the vehicle’s trailer socket but protected from road debris and moisture.
- If upgrading to high-output LED lights, use the adaptor at the same time to prevent signal issues.
- After towing, especially over rough terrain, inspect plugs and connectors for wear or damage.
- Carry a spare 12V fuse for the towing circuit to quickly fix any loss of signal.
