Reese is a well-known company that manufactures hitching and trailering equipment. One of their most popular products is the brake controller, which ensures that your trailer brakes are synced with your tow vehicle. In this article, we’ll cover the basics of the Reese brake controller wiring diagram, including how to install and troubleshoot it.
What is a Brake Controller and Why Do You Need It?
Before we delve into the details of the wiring diagram, let’s first discuss what a brake controller is and why it’s important. A brake controller is a device that controls the electric brakes on your trailer. It’s installed in the cab of your tow vehicle and sends signals to the trailer’s electric brakes, allowing you to stop smoothly and safely.
Without a brake controller, your trailer’s brakes would be inactive, putting a strain on your tow vehicle’s brakes and making it difficult to stop. Additionally, many states require a brake controller to be installed on trailers that weigh over a certain amount.
Reese Brake Controller Wiring Diagram Overview
The Reese brake controller wiring diagram is a simple but crucial diagram that helps you to connect the controller to your tow vehicle and trailer. It consists of four wires: the black wire connects to the battery, the red wire connects to the brake switch, the white wire connects to the ground, and the blue wire connects to the trailer brakes.
It’s important to note that the wiring diagram may vary depending on the make and model of your trailer and tow vehicle. Always refer to the specific instructions provided by Reese for your particular brake controller.
Step-by-Step Guide to Installing a Reese Brake Controller
Now that you understand the basics of the wiring diagram, let’s go through the steps of how to install a Reese brake controller.
Step 1: Gather Supplies
Before you start the installation process, make sure you have all the necessary supplies. This includes a Reese brake controller, a mounting bracket, screws, wires, wire strippers, and crimpers.
Step 2: Mount the Brake Controller
Mount the brake controller in a convenient location in your tow vehicle. Make sure it’s easily accessible and won’t interfere with your driving. Use the included mounting bracket and screws to secure it in place.
Step 3: Connect the Black Wire
Connect the black wire from the brake controller to the positive terminal of your tow vehicle’s battery. Use wire strippers to remove the insulation from the black wire, and then use a crimping tool to connect it to the battery terminal.
Step 4: Connect the Red Wire
Connect the red wire from the brake controller to the brake switch in your tow vehicle. This will allow the brake controller to sense when you apply your vehicle brakes and send signals to your trailer’s electric brakes.
Step 5: Connect the White Wire
Connect the white wire from the brake controller to the ground in your tow vehicle. This will ensure that the brake controller is properly grounded and functioning correctly.
Step 6: Connect the Blue Wire
Connect the blue wire from the brake controller to the trailer brakes. This will allow the brake controller to send signals to the trailer’s electric brakes and control their intensity.
Once you’ve completed all these steps, test the brake controller to make sure it’s working properly.
