FAQ – Wiring Kit for Ford S-Max

Do I need a 13-pin wiring kit?

Yes – if you want features like permanent power feed, charging line, or trailer reverse lighting. For basic lighting, a 7-pin kit is often sufficient.

Is activation or coding required?

Some S-Max trims with sensors, rear camera or extended assist systems may require module activation or configuration. Check descriptions carefully.

Can I do the installation myself?

Yes – with proper tools and attention to instructions, many users can install themselves. If unsure, seek professional assistance.

Will this affect the warranty?

No – when using certified, vehicle-specific components, properly installed, your manufacturer’s warranty should remain intact.

How do I determine my exact year & trim?

Check your registration documents or VIN. Also check for features like sensors, cameras or existing tow connection points – these help select the correct wiring kit.
