What is a Brake Controller?

If you’re new to brake controllers, you should know that they are devices that allow you to control your trailer brakes from your vehicle. They work by sending an electrical signal from your vehicle to your trailer brakes, instructing them to engage or disengage. This can be useful when you’re towing a heavy load, as it can help you slow down more efficiently and prevent accidents.

There are two types of electric brake controllers: Time-Delayed Brake Controllers and Proportional Brake Controllers. In this article, we will be focusing on Time-Delayed Brake Controllers, as they are the most common ones and are easier to install.

Step-by-Step Guide to 2012 Silverado Brake Controller Wiring Diagram:

Step 1: Mounting the Brake Controller

The first step is to mount the brake controller in your vehicle. The best place to mount the brake controller is under the dashboard, near the driver’s side. Make sure that the controller is easily accessible but not in the way of the driver’s legs.

Step 2: Connecting the Wiring Harness to the Brake Controller

Once you have mounted the brake controller, connect the wiring harness to the controller. The wiring harness will have a plug that matches the port on the back of the brake controller. Insert the plug into the controller and secure it in place.

Step 3: Finding the Brake Light Switch Wire

In this step, you’ll need to locate the wire that connects the brake light switch to the stoplight circuit. The brake light switch is located under the dashboard, near the brake pedal. Check the manufacturer’s manual for your vehicle to locate the correct wire.

Step 4: Connecting the Brake Controller Wire to the Brake Light Switch Wire

Strip off the insulation from the brake light switch wire using a wire stripper. Then, use a wire connector to join the brake controller wire to the brake light switch wire. Tighten the wire connectors properly and insulate the joint with electrical tape.

Step 5: Connecting the Brake Controller Wire to the Battery

You’ll need to connect the brake controller wire to a 12V power source. The best option is the vehicle’s battery. Locate the positive (+) and negative (-) battery terminals and use the wire crimping tool to attach the brake controller wire to the positive terminal. Insulate the joint with electrical tape.

Step 6: Testing the Brake Controller

With all the wiring done, it’s time to test the brake controller. First, turn on the vehicle’s ignition and check if the brake controller is powered on. Next, connect your trailer to your vehicle and test the brake controller. Apply the brakes and check if the trailer brakes engage in sync with the vehicle’s brakes. If they do, congratulations! You have successfully installed a brake controller in your 2012 Silverado.
