Features of our wiring kits

Plug-and-play installation without modifications to the factory wiring harness.

7-pin or 13-pin – which version is right?

The 7-pin wiring kit covers all standard lighting functions: indicators, tail lights, brake lights. The 13-pin kit adds permanent power feed, charging line, and possibly reversing lights – ideal for caravans or when extra functions are required.

Installation & technical notes

Solder or join connectors properly and ensure correct fuse protection; wrong wiring can cause malfunctions.
For vehicles with camera, sensors or advanced driver assistance, coding or activation may be needed.
Make sure connectors are sealed and water-proof – especially important in wet or winter conditions.

The kit comes with a detailed installation guide. If you have mechanical knowledge and correct tools, self-installation is possible; otherwise we recommend professional installation.

FAQ – Wiring Kit for Ford Grand C-Max

Do I need a 13-pin wiring kit?

Only if your trailer or accessories require features like permanent power feed, charging line, or extra power. For basic lighting, a 7-pin wiring kit is sufficient.

Is coding or activation required?

Yes – on some Grand C-Max variants with reversing camera, parking sensors, or advanced assistance systems. Check the product description and manual.

Can I do the installation myself?

Yes, if you have tools and mechanical know-how. Ensure correct connections and follow the instructions. If unsure, a professional workshop is advisable.

Will fitting this affect my vehicle warranty?

No – when using certified, vehicle-specific parts and installing correctly, the manufacturer’s warranty usually remains intact.

How do I determine my exact year and trim?

Check your registration documents or VIN (Vehicle Identification Number). Also inspect vehicle for equipment like sensors or reversing camera. These details help you select the correct wiring kit.
