A wiring kit for the Renault Master III ensures lighting, indicator, and signal functions between your van and trailer or bike carrier operate safely, reliably, and in compliance with regulations. Our kits are precisely adapted to the vehicle’s wiring, equipment, and usage requirements.

Advantages of our Master III wiring kits

7- or 13-pin socket options: Standard lighting can often be handled with 7 pins; for reverse lights, rear fog lights or additional comfort features, the 13-pin version is advisable.
Interface / module integration: Many kits include modules to connect with existing vehicle systems, such as disabling sensor systems when towing.
LED compatibility & reliable signal functions: Modern lighting technologies are recognized; indicators, reverse and brake lights are correctly powered.
Durable & weatherproof components: Connectors, cable insulation and plugs are designed to withstand heavy use and changing weather conditions.
Wide choice & pricing: Many variations available — from basic kits to premium ones with additional modules — so you can choose according to your needs and budget.

Technology & Installation

Our wiring kits include the harness, socket (7- or 13-pin), control / relay modules, mounting accessories, and clear instructions. With vehicles that already have towbar wiring preparation, installation typically takes about 60-90 minutes, possibly less for simpler kits. Depending on trim and electronics, activation or coding may be necessary afterward so that all light and signal functions are properly detected and warning lights avoided. Professional installation is recommended.

Why choose a wiring kit for the Renault Master III?

The Master III offers high payloads, flexibility and modern features – ideal for commercial work, frequent towing or private use with trailers or bike racks. A high-quality wiring kit extends its functionality – ensuring light & signal connections that are durable, safe and legally compliant even under demanding conditions.

Frequently Asked Questions (FAQ)

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

If you only need standard lights like indicators, tail and brake lights, a 7-pin kit will often suffice. For reverse lights, rear fog lights, comfort extras or heavy towing use, the 13-pin variant is recommended.

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

Yes – many vehicle-specific kits include this feature to avoid false alarms or warning signals when a trailer is connected.

3. Is coding or activation required after installation?

That depends on the model year, trim, and vehicle electronics. Some Master III variants require activation or configuration to ensure all signal and lighting functions are recognized correctly, without warning faults.
