Technical Data & Highlights

Braked towing capacity: approx. 2,200 kg.
Unbraked towing capacity: around 750 kg.
Tongue load (tow ball load): ~80-100 kg, depending on the specific model.
Curb weight and optional equipment strongly affect how much you can tow safely.
Weatherproof connectors and corrosion-protected materials are essential for durability, especially with wiring or sockets exposed under the rear bumper.
Check compatibility with reversing camera, sensors or driver assistance systems; some versions may require coding or activation for full functionality.

7-pin vs. 13-pin – which version suits?

A 7-pin wiring kit is sufficient for standard lighting functions like indicators, tail and brake lights. A 13-pin wiring kit adds features such as constant power feed, accessory lines and reverse trailer light – especially useful when towing heavier trailers or frequently using powered accessories.

Installation & Practical Advice

Follow the installation instructions carefully; check all connectors, fuse ratings and mounting points.
Route cables neatly; mount the socket in a weather-protected position; seal connections against moisture.
Ensure a solid ground connection; avoid overloading the vehicle’s electrical system.
If your QX70 has advanced features like sensors or cameras, verify whether coding or activation is required.

FAQ – Wiring Kit for Infiniti QX70

Do I need a 13-pin wiring kit?

If you tow regularly or use powered accessories (lights, charging, etc.), then yes. For basic lighting or occasional towing, a 7-pin kit is usually sufficient.

Is coding or activation required?

Yes – especially for trims with camera or sensor features; some wiring outputs may only work properly after activation.

Can I install it myself?

Yes – with suitable tools, careful routing, and weatherproof connections. If you are not confident, having it installed by a professional is better.

Will installation affect warranty?

No – using certified, vehicle-specific parts and ensuring the installation is done well generally preserves the manufacturer’s warranty.

Which version is best for frequent towing?

The 13-pin wiring kit offers more flexibility, safety and features for frequent towing and powered accessories. The 7-pin version is fine for lighter or occasional towing.
