Our vehicle-specific wiring kit for the Ford Transit Custom provides a safe, regulation-compliant electrical connection for trailers, bike racks or powered accessories. Sets are precisely matched to build year, trim and onboard systems, ensuring lighting, signalling and comfort features work reliably – even on vehicles without factory preparation.

Features of our Transit Custom wiring kits

Available in 7-pin standard versions and 13-pin premium versions with additional features like permanent power feed and charging line.
Many kits include a CAN-Bus module; parking sensors (PDC) disconnection/adjustment can be supported.
LED-compatible sockets, weatherproof materials and corrosion-protected connectors.
Activation or coding required to ensure full compatibility of all functions.

7-pin vs. 13-pin – which one should you choose?

The 7-pin kit covers basic lighting and signalling: blinkers, tail lights, brake lights. The 13-pin alternative adds functions like reverse lights for the trailer, charge line, permanent power and LED compatibility – ideal for trailers with electric loads or advanced accessories.

Installation & technical advice

Detailed installation guide included – check connectors, secure mounting points and fuse ratings carefully.
Route cable cleanly, protect from moisture, heat and wear; mount sockets in protected locations.
If vehicle has sensors, rear camera or assist systems, check if coding/activation is necessary.
For trailers with electrical demands, ensure that the 13-pin kit’s additional power lines are properly installed.

FAQ – Wiring Kit for Ford Transit Custom

Do I need a 13-pin wiring kit?

Yes, if you plan to use features like permanent power feed, charge line, reverse lighting or LED trailer lighting. For basic lighting/signals only, a 7-pin kit is usually sufficient.

Is coding or activation required?

Often yes — especially with parking assistance, rear camera or when no factory-installed wiring is present.

Can I install it myself?

Yes, with proper tools and attention to detail. Make sure connectors are sealed, cable routing is clean and fuses correct. In uncertain cases, professional installation is recommended.

Will installation affect my warranty?

No — using certified, vehicle-specific components and correct installation generally retains the manufacturer’s warranty.

Is my Transit Custom prepared from the factory?

Many models from mid-2016 onward have some degree of preparation (CAN-Bus modules, connector sockets), but check your vehicle’s documentation or inspect rear area for blank plugs or wiring points.
