Frequently Asked Questions (FAQ)

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

If you only need basic lighting like indicators, tail lights and brake lights, a 7-pin set may suffice. For reverse lights, additional lighting or comfort features, the 13-pin variant offers more flexibility.

2. Is coding or activation needed after fitting?

That depends on the model year and your vehicle’s equipment. Many Mégane II Grandtour versions don’t require extensive coding, but if extra functions are added, some activation or configuration may be necessary.

3. What should I pay attention to during installation?

Good grounding, weather-proof connectors, sufficient cable gauge, and proper cable routing are key to ensure long-term functionality and safety.
