Ford Transit (2015–Present Cargo and Passenger Van) Flat-4 Wiring Installation

Vehicle Coverage: 2015–Present Cargo and Passenger Van Ford Transit; exact trim and factory tow preparation are verified before scheduling
Output: 4-way flat
Connection Method: Passive, vehicle-appropriate wiring; no programmed active towing module
Finished Connector Location: Mounted outside beside the receiver for regular commercial or towing access.
Installation Time: Approximately 2–3 hours
Connector Location: Mounted outside beside the receiver for regular commercial or towing access.
The Transit uses a powered passive converter connected to the rear lamp circuits with a protected fused feed. The finished flat-4 is mounted outside at the hitch rather than left loose in the cargo area.
1. Verifying Body and Lamp Configuration
Rear body type, lamp connectors, upfit wiring, and any existing tow provision are inspected before the harness is selected.
2. Accessing Both Rear Lamp Circuits
Rear lamp assemblies or interior access panels are opened without cutting the original lighting wires.
3. Installing the Passive Converter
Vehicle-specific connections are seated, a clean ground is established, and the module is secured in a protected location.
4. Routing Protected Power
A fused battery feed is supported along the van away from exhaust heat, sharp edges, and moving components.
5. Mounting and Testing the Exterior Flat-4
The connector is mounted beside the receiver and every lighting output and the ground are tested before access panels are restored.
Our Wiring Standard: Lighting outputs, ground integrity, and any added auxiliary or brake-output circuit are tested before the installation is closed.
