Connector Location: Mounted outside near the receiver and protected with a weather cover.

For Explorers without usable factory trailer wiring, a passive vehicle-specific harness connects at Ford’s prepared rear tow circuit or rear lamp connections, depending on equipment. We verify the vehicle before selecting the method.

1. Checking Factory Tow Preparation

The rear connector, fuse positions, and existing tow equipment are inspected before any trim is opened.

2. Accessing the Correct Rear Connection

The prepared tow socket or exact-fit rear lamp connectors are exposed without cutting the factory harness.

3. Installing and Securing the Passive Harness

The connection is locked, grounded where required, and supported away from the exhaust and suspension.

4. Positioning the Exterior Plug

The flat-4 is secured at the receiver so it is accessible without dragging below the bumper.

5. Testing All Lighting Outputs

Running, brake, turn, and ground circuits are function-tested before the access area is closed.

Our Wiring Standard: Lighting outputs, ground integrity, and any added auxiliary or brake-output circuit are tested before the installation is closed.
