If you’re a frequent traveler or hauler, you already know that maneuvering a trailer can be a hassle, not to mention risky. But with electric brakes, your job can be made quite easier. However, installing electric brakes on a trailer isn’t the easiest process, and it can be a bit of a headache if you’re not mechanically inclined. This article will show you a step-by-step process of wiring electric brakes on a trailer, along with some helpful tips and hints.

The Importance of Electric Brakes on a Trailer

Maneuvering a trailer laden with heavy stuff can be difficult, and even the slightest mistake can lead to fatal accidents. Electric trailer brakes serve an important role in preventing these incidents. Trailer brakes are designed to operate with the tow vehicle brake system, providing reliable and secure stopping power, which makes your journey hassle-free and risk-free.

What Are Electric Brakes On A Trailer?

Basically, electric brakes on a trailer are drum brakes that come fitted on the wheels of a trailer. These brakes are activated by a controller system installed in the tow vehicle, and they work by applying pressure to the brake drums, which in turn slows down the trailer.

What You Need To Wire Electric Brakes On A Trailer?

Before we jump into the nitty-gritty of wiring electric brakes on a trailer, let’s take a look at the things you’ll need:

  • A brake controller.
  • A suitable wiring harness for connecting the brake controller to the trailer.
  • A basic toolset, which includes wire strippers, pliers, and screwdrivers, among others.
  • A voltage meter.
  • An electric drill, if you are running new wiring.

Wiring Electric Brakes On A Trailer: A Step-by-Step Guide

Wiring electric brakes on a trailer is a step-by-step process, and here are the steps involved:

Step 1: Install The Brake Controller

Install The Brake ControllerThe first thing you’ll need to do is install a brake controller in your tow vehicle. Use a universal brake controller wiring kit to connect the controller into the tow vehicle’s electrical system. Most brake controllers come with instructions for installation.

Step 2: Run The Wiring Harness

Run The Wiring HarnessRun the wiring harness from the brake controller to the trailer. Follow the manufacturer’s instructions for the specific brake controller and make sure that you have the required connectors, breakers, and other parts.

Step 3: Connect The Wiring

Connect The WiringAfter running the wiring harness, connect the wiring for the brake controller to the trailer’s wiring system. The wire colors on the trailer’s wiring system correspond to the electrical functions needed to run the trailer lights, turn signals, and brake lights. Make sure you use a voltage meter to check for the electrical function before connecting the wiring.

Step 4: Test The System

Test The SystemAt this point, you should have the brake controller and trailer wiring installed and connected correctly. You can now test the system by driving the tow vehicle and applying the brakes. This will activate the trailer’s electric brakes, which should stop the trailer smoothly without any jarring movement. If the brakes do not work, you should disconnect and recheck your work.
