- For Ford Full-Size Vans: Underneath and to the left of the steering column.
- For Ford Explorer/Mercury Mountaineer:
- Behind the glove box on the passenger side, or
- Underneath and to the left of the steering column, taped to another harness near the emergency brake pedal.
- Identify the 6-pin connector that matches the adapter’s plug.
Step 2: Verify Battery Power
- Use a test light to probe the connector and verify that battery power is supplied.
- Alternatively, follow the wires from the connector to ensure they are not disconnected behind the instrument panel.
If battery power is present:
- Proceed to Step 4.
If no battery power is present:
- Follow Step 3 to add power.
Step 3: Add Power to the Connector
- Use an electric brake control wiring kit to route the required wires as follows:
- Cut the battery feed wire at the vehicle connector, leaving enough wire to splice.
- Use the supplied butt connector to connect the wiring kit’s battery feed wire to the vehicle harness.
- Cut the trailer brake wire at the vehicle connector, leaving enough wire to splice.
- Connect the wiring kit’s trailer brake wire using the supplied butt connector.
Step 4: Connect the Adapter
- Plug the brake control adapter into the vehicle’s electric brake control harness connector.
- Follow the brake control manufacturer’s installation instructions to wire and mount the brake controller unit.
Step 5: Test the Installation
- Complete the installation as instructed by the brake control manufacturer.
- Perform all test procedures to verify proper operation of the trailer brake system.
Warnings:
- Overloading the Circuit May Cause Fires:
- DO NOT exceed the lower of the following:
- The vehicle manufacturer’s towing rating, or
- Maximum Capacity: 4 axles / 8 brakes (24 amps).
- DO NOT exceed the lower of the following:
- Always read and follow the vehicle owner’s manual and the brake controller installation instructions.
Wiring Overview:
- Battery Feed (Fused): Supplies power to the brake controller.
- Ground: Ensures proper grounding for the brake controller system.
- Stop Lamp Switch (Input): Provides a braking signal to the brake controller.
- Trailer Brake Controller (Output): Sends braking signals to the trailer brakes.
Safety Notes:
- Verify all wiring connections are secure and routed away from:
- Sharp edges
- Hot surfaces
- Moving parts
- Inspect the adapter and wiring periodically for wear or damage.
