FAQ – Wiring Kit for Ford Transit Custom II

Do I need a 13-pin kit?

Yes, if you plan to power accessories, use reverse lighting or tow a caravan. For basic lighting functions, a 7-pin kit is sufficient.

Is activation or coding required?

Yes – especially for vehicles with rear camera, parking sensors or LED lighting. Without coding, some functions may not work properly.

Can I install the kit myself?

Yes, with proper tools and care. Weatherproof connections, correct fuses and tidy wiring are essential. If unsure, professional installation is recommended.

Will installation affect my warranty?

No – when using certified, vehicle-specific parts and correct installation, your warranty should remain valid.
