Getting Started

Before you start the installation process, you will need to gather a few materials:

Materials Tools
Brake controller Wire stripper
Wire harness Tape measure
Electrical tape Socket wrench set
Zip ties Drill

Once you have all the necessary materials and tools, you can get started with the installation process.

Step 1: Locate the Brake Controller Connector

The first step in installing a brake controller on your Ford F250 is to locate the brake controller connector. This connector is typically located under the dash on the driver’s side of the vehicle.

Using your tape measure, measure the distance from the brake controller connector to the mounting location. This will help you determine the length of wire harness that you will need to purchase.

Step 2: Install the Brake Controller

Once you have located the brake controller connector and determined the length of wire harness that you will need, you can begin installing the brake controller.

  1. Mount the brake controller in a convenient location, such as under the dash or on the center console.
  2. Using the socket wrench set, secure the brake controller to the mounting location.
  3. Attach the wire harness to the brake controller, following the manufacturer’s instructions.

Step 3: Connect the Wires

Now that you have installed the brake controller, it is time to connect the wires.

  1. Connect the red wire from the wire harness to the brake switch wire, which is located under the dash on the driver’s side of the vehicle.
  2. Connect the black wire from the wire harness to the negative battery terminal under the hood of the vehicle.
  3. Connect the blue wire from the wire harness to the trailer brake wire, which is typically located under the dash on the driver’s side of the vehicle.
  4. Connect the white wire from the wire harness to the ground wire, which is also located under the dash on the driver’s side of the vehicle.

Once all the wires are connected, wrap them in electrical tape to protect them from wear and tear. Use zip ties to secure the wires in place and prevent them from dangling.
