FAQ – Frequently Asked Questions for Wiring Kits on Citroën C4 III

Which type of plug is recommended for the C4 III?

Whether you should choose a 7-pin or 13-pin connector depends on the functions you want—additional features like reverse lights or constant power require more pins.

Are these kits weather-proof?

Yes, our wiring kits are designed with weather-sealed connectors and high quality insulation to reduce moisture and corrosion risks.

Will sensors or driver assistance systems be affected?

If installed correctly, parking, rear- or backup sensors should continue to work. We can advise you in case of special equipment or configurations.
