A wiring kit for the Renault Laguna III (approx. model years 2007-2015) ensures lighting, indicator, and signal functions between your vehicle and a trailer or bike rack operate safely, reliably and in compliance with regulations. Our kits are tailored to the wiring, trim, and electronics of this advanced generation.

Benefits of our Laguna III wiring kits

7- or 13-pin socket options: A 7-pin setup is often sufficient for standard lighting; if you require reverse lights, permanent power or additional comfort features, the 13-pin variant is preferred.
Proper harness & OEM-style connectors: Harnesses and connection modules are designed to integrate with the vehicle’s existing wiring harness to minimize work and ensure reliability.
LED lighting & signal monitoring: Modern trailer LED lighting is properly recognised, light & blink signals reliably transmitted, and warning indicators for defective lamps available in many kits.
Parking sensor / PDC shut-off when towing: Sensors or parking assistance systems can be disabled automatically when a trailer or bike rack is connected to avoid false warnings.
Durable & weatherproof build: Connectors, cable insulation, housings are built to endure frequent use and variable weather conditions.

Technology & Installation

Our wiring kits include harness, socket (7- or 13-pin depending on variant), relay / control / interface modules, mounting accessories and a detailed manual. If your vehicle already has towbar wiring preparation, installation usually takes about 60-90 minutes. Depending on trim, electronic equipment and vehicle version, activation or coding may be required after installation so that all signal functions are properly recognised and no warning indicators remain. Professional installation is advised.

Why choose a wiring kit for the Renault Laguna III?

The Laguna III offers comfort, technology and stable driving characteristics. A high quality wiring kit increases its flexibility – for towing, leisure or transport use – ensuring that lighting & signal connections stay reliable, safe and in line with regulations in real use.

Frequently Asked Questions (FAQ)

1. Is a 7-pin socket enough or should I choose 13-pin?

If you only need standard lighting like indicators, tail & brake lights, a 7-pin set is often enough. For reverse lights, extra features or additional lighting, the 13-pin version is better.

2. Will parking sensors / PDC deactivate automatically when towing?

Yes – many Laguna III specific kits offer this functionality to avoid false sensor alerts when towing.

3. Is activation or coding required after fitting?

That depends on the model year and your vehicle’s equipment. Vehicles with advanced electronics or assistance systems may require activation or coding to ensure all functions are recognised correctly without warning lights.
