Wiring Kits for Renault Grand Scénic III – vehicle-specific & powerful

A wiring kit for the Renault Grand Scénic III (approx. April 2009 to August 2016) ensures lighting, indicator and signal functions between your car and a trailer or bike rack operate safely, reliably, and in compliance with regulations. Our kits are precisely adapted to the vehicle’s electrical system, trim and electronic architecture.

Advantages of our Grand Scénic III wiring kits

7- or 13-pin socket options: A 7-pin version often suffices for standard lighting—tail lights, indicators, brake lights. If you require reverse lights, constant power or additional comfort features, a 13-pin kit is recommended.
Vehicle-specific harness & relay/control modules: Connectors and modules are designed to integrate cleanly with the OEM wiring for easier installation and robust performance.
LED trailer lighting & signal monitoring: Modern lighting systems, including LED trailer lights, are supported and correctly driven.
Parking sensor disable when towing: Parking and reversing sensors can be automatically deactivated when a trailer is attached to avoid false warnings.
Durable & weatherproof components: Connectors, cable insulation and protective housings are built to withstand frequent use and various weather conditions.

Technology & Installation

Our wiring kits include harness, socket (7- or 13-pin depending on variant), relay or control module, mounting hardware, and clear instructions. If your vehicle already has towbar wiring preparation, installation typically takes about 60-90 minutes. Depending on trim and electronics, coding or activation may be required post-installation so that all signal functions are recognized correctly and warning messages avoided. Professional installation is recommended.

Why choose a wiring kit for the Renault Grand Scénic III?

The Grand Scénic III offers space, comfort and versatility. A premium wiring kit increases its usability – for trailers, transport or leisure use – ensuring lighting & signal connections are safe, reliable, and compliant in everyday driving.

Frequently Asked Questions (FAQ)

1. Is a 7-pin kit sufficient or should I go with a 13-pin?

If you only need standard lighting—tail lights, indicators and brakes—a 7-pin set is usually enough. For reverse lights, continuous power or additional features, choose the 13-pin option.

2. Will parking / reversing sensors disable automatically when towing?

Yes – many vehicle-specific kits include this feature to avoid false sensor warnings when a trailer is connected.

3. Is coding or activation required after installation?

It depends on the model year and trim. Grand Scénic III vehicles with additional comfort or assist systems often require activation or coding so that all lighting and signal functions are correctly recognised and no warning indicators appear.
