Wiring Kits for Renault Master IV – rugged & vehicle-specific

A wiring kit for the Renault Master IV ensures lighting, indicator, and signal functions between your vehicle and trailer or bike rack work safely, reliably and in compliance with regulations. Our kits are precisely tailored to the wiring, features, and usage demands of this class of transporter.

Benefits of our Master IV wiring kits

7- or 13-pin socket options: The 7-pin version supports basic lighting (indicators, tail & brake lights); the 13-pin includes reverse lights, permanent power and additional comfort features.
OE loom & high-quality parts: Kits with original connectors, relay/control modules for clean, durable integration with vehicle electronics.
Standard-compliant sockets (DIN/ISO): Many 13-pin versions conform to ISO 11446, improving compatibility and safety.
Robust & weatherproof build: Wires, contacts and housings built to withstand moisture, dirt and frequent use.
Reduced install time with prepared components: When tow-bar or wiring connector is pre-fitted, installation becomes significantly more efficient.

Technology & Installation

Our wiring kits include harness, socket (7- or 13-pin), relay/control modules, mounting hardware and clear instructions. On Renault Master IV vehicles with existing towbar or connector prep, fitting usually takes about 60-90 minutes. Depending on equipment and onboard electronics, activation or coding may be required to ensure all lighting, signal and comfort functions are recognised and warning messages avoided. Professional installation is advised.

Why choose a wiring kit for the Renault Master IV?

The Master IV is built for heavy use, transportation and demanding tasks. A high-quality wiring kit expands its versatility – towing trailers, transporting equipment or leisure gear – while ensuring signal & lighting performance remains reliable even under high load.

Frequently Asked Questions (FAQ)

1. Should I go with a 7-pin or 13-pin socket?

For essential lighting like indicators, tail, and brake lights, a 7-pin socket often suffices. If you need extra functionality like reverse lighting, continuous power or comfort features, the 13-pin version is the better choice.

2. Is coding or activation needed after installation?

It depends on trim level and electronics package. Many Master IV variants without advanced light or driver assistance features need no coding; with added systems, activation may be needed.

3. What should I pay attention to during installation?

Ensure solid grounding, weather-proof connectors, proper cable gauge and that the socket complies with standards are key to long term safety and reliable performance.
