Installation & Technical Notes

Check for features like reversing camera, parking sensors or driver-assist systems before installation – these may need adjustments or activation.
Ensure connectors are securely mounted; route cables so they are protected from heat, moisture, and mechanical wear.
Use appropriately rated fuses; ensure vehicle’s electrical system supports trailer lighting and accessory loads safely.
Select a wiring kit that is mechanically and electrically suited for the towing capacity, especially if you use the vehicle often for towing.

FAQ – Frequently Asked Questions

Which wiring kit (7- or 13-pin) should I choose?
A 7-pin kit is usually sufficient for basic lighting (tail, brake, indicators). If you need reverse lights, constant power or accessory usage, a 13-pin kit is better.

Is coding or activation required?
That depends on model year and equipment. Hybrid models like the NX 350h frequently include assist and comfort systems; control units may need to recognize added signals and may require coding or activation.

Can I install the wiring kit myself?
Yes — with proper tools and basic knowledge of vehicle electrical systems it is feasible. For complex equipment or if warning messages appear, a professional installation is safer.

Is the wiring kit weatherproof and durable?
Yes — our wiring kits use weather-sealed connectors, high-quality insulation and materials designed to resist environmental stress, moisture, and corrosion.

What should I do if warning messages or electrical faults appear?
These often stem from loose connectors, incorrect wiring, or unsuitable components. Proper installation, correct fuse sizing, and if necessary additional relay or auxiliary modules generally resolve these issues and ensure reliable operation.
