FAQ – Wiring Kit for Hyundai H-350

Do I need a 13-pin wiring kit?

If you plan to use trailers with electrical needs (trailer lights, reverse lights, permanent power etc.) or tow often, a 13-pin kit is recommended. For basic lighting alone, a 7-pin kit is usually sufficient.

Is coding or activation required?

Yes – for versions with sensors, cameras or advanced assistance, coding or activation might be needed for all functions to work properly.

Can I install the kit myself?

Yes – with correct tools, clean routing, and making sure wiring is protected. Weather proof connectors and correct fuse ratings are essential. If unsure, consult a professional.

Will installation affect warranty?

No – when using vehicle-specific, certified components and correct installation, the manufacturer’s warranty is generally preserved.

Which version is better for frequent towing?

For regular trailer use or accessories requiring power, the 13-pin version offers more flexibility and safety. For occasional towing, the 7-pin version is often sufficient.
