Installation & Technical Notes

Check whether your vehicle has rear-view camera, parking sensors, or driver-assist systems — these often need calibration or activation when wiring in trailer lights.
Ensure connectors are mounted securely; wires routed in protected paths, away from heat, moisture or sharp edges.
Use correctly rated fuses; the vehicle’s electrical system must handle trailer lighting load and any extra accessories without overload.
Select a wiring kit that is mechanically and electrically appropriate for the towing limits of the vehicle — especially for regular or heavy towing.

FAQ – Frequently Asked Questions

Which wiring kit (7- or 13-pin) should I choose?
A 7-pin kit is usually enough for standard lighting (tail, brakes, indicators). If you want reverse lights, constant power or accessories, a 13-pin kit is better.

Is coding or activation required?
It depends on year & equipment. Some NX 300h models have comfort or assist systems which need new lighting or power signals to be correctly recognized by the vehicle‘s control units; coding or activation may be necessary.

Can I install the wiring kit myself?
Yes — with suitable tools and a basic understanding of vehicle electrics it’s feasible. If you have many sensors, accessories or warning messages, 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 moisture, corrosion and environmental stress.

What should I do if warning messages or electrical faults appear?
Such issues often stem from loose connectors, incorrect wiring paths or incorrect fuse size. Careful installation, appropriate components and, if necessary, auxiliary modules or relays, will usually resolve them and restore safe, reliable operation.
