Introduction:
When it comes to installing tow bar wiring on your Ford Transit Custom, there are crucial considerations to ensure a seamless process. From choosing the right pin format to determining the engine model and trailer prep status, this guide will walk you through the essential steps.
1. Pin Format and Electrics:
Before diving into the installation, decide on the pin format (7 or 13 pins) and whether you need wiring solely for trailer lights or both trailer lights and caravan electrics.
2. Engine Model Compatibility:
Identify your Transit Custom’s engine model – 2.0L Euro 6, 2.0L Euro 6.2, or 2.2L Euro 5. Different models have distinct connector plugs, impacting your wiring kit selection.
3. Trailer Prep Explained:
Understanding “trailer prep” is crucial. For Ford Transit Custom, it may involve locating a (blanked off) plug between the spare wheel holder and the near side rear wheel arch. Refer to the image below for clarity.
4. Advantage of Trailer Prep:
If your van has trailer prep, opting for a wiring kit designed for it offers cost savings and quicker installation. For instance, the 7 Pin tow bar wiring kit for the 2.0L Euro 6 with Prep is the most economical and rapid solution.
5. Main Connections Placement:
Regardless of trailer prep, main connections occur in the front passenger footwell. Kits for models without trailer prep run the wiring from the rear towing socket along the chassis rail to the footwell, making them versatile for vans with or without trailer prep.
6. Coding Requirement:
Post-installation, coding is essential. Connect the van to a diagnostic scanner for the relevant coding work, ensuring proper operation of trailer lights and additional safety functions integrated by Ford.
7. Wiring Faults and Installation Tips:
Modern wiring is reliable, but improper installation of the control box in the front passenger footwell may cause faults. Ensure correct orientation, as shown in the image below, to prevent water damage. Note that water damage is not covered by the warranty.
