Brake Force Trailer Brake Controller Wiring Diagram

If you own a trailer, one of the most important things to have installed is a brake controller. A brake controller allows you to control the electric brakes on the trailer from inside the towing vehicle, providing additional stopping power and safety. One of the most popular brake controllers on the market is the Brake Force controller. In this article, we will go over the wiring diagram for the Brake Force controller, and answer some frequently asked questions.

What is a Brake Controller?

A brake controller is an electronic device that’s installed in the towing vehicle to control the electric brakes on the trailer. When you apply the brakes on the towing vehicle, the brake controller sends a signal to the trailer’s electric brakes, which activates them to slow down or stop the trailer. This provides additional stopping power and greater safety when towing heavy loads.

There are three types of brake controllers: time-delayed, proportional, and hydraulic. Time-delayed brake controllers apply a preset amount of braking power after a delay. Proportional brake controllers apply the trailer brakes in proportion to the pressure applied to the towing vehicle’s brakes. Hydraulic brake controllers use the towing vehicle’s brake fluid pressure to activate the trailer’s hydraulic brakes.

What is the Brake Force Controller?

The Brake Force controller is a time-delayed brake controller that provides excellent stopping power and control for trailers with electric brakes. It is one of the most popular and reliable brake controllers on the market, and is manufactured by Hopkins Manufacturing Corporation.

Wiring Diagram for the Brake Force Controller

The wiring diagram for the Brake Force controller is relatively simple and straightforward. It consists of four wires that need to be connected to the towing vehicle and the trailer:

Wire Color Function Connection
Black Battery Positive Connect to Battery Positive (+)
White Ground Connect to Ground (-)
Blue Brake Output Connect to the Trailer Brake Wire
Red Stoplight Input Connect to the Tow Vehicle Stoplight Switch Wire

The Brake Force controller also has a manual override switch that allows the driver to apply the trailer brakes independent of the towing vehicle’s brakes. The manual override switch is usually located on the controller itself, and can be activated by pushing or sliding the switch.

FAQs

1. Do I need a brake controller for my trailer?

If your trailer has electric brakes, or if it weighs more than 1,500 pounds (without brakes), you are legally required to have a brake controller installed in the towing vehicle. Even if your trailer is under the weight limit, a brake controller is recommended for greater safety and control when towing heavy loads.

2. Can I install the Brake Force controller myself?

Yes, the Brake Force controller can be installed by a DIYer with some basic electrical knowledge and tools. However, if you are not comfortable working with electrical wiring, it is recommended to have a professional install the controller for you.

3. What is the difference between a time-delayed and proportional brake controller?

A time-delayed brake controller applies a preset amount of braking power after a delay, while a proportional brake controller applies the trailer brakes in proportion to the pressure applied to the towing vehicle’s brakes. Proportional brake controllers provide smoother and more predictable braking, and are recommended for towing heavy loads or in situations where sudden stops may be necessary.

4. How do I know if my Brake Force controller is working properly?

You can test your Brake Force controller by performing a brake power output test. This involves adjusting the controller’s power output settings to a low level, and then gradually increasing the power while applying the brakes. The trailer brakes should engage smoothly and evenly, without locking up or skidding. If you notice any irregularities or problems, it is recommended to have the controller inspected by a professional.

5. Can I use the Brake Force controller with hydraulic brakes?

No, the Brake Force controller is designed to work with trailers that have electric brakes only. If your trailer has hydraulic brakes, you will need to install a hydraulic brake controller instead.

Conclusion

Installing a brake controller on your towing vehicle is essential for safe and controlled towing. The Brake Force controller is a popular and reliable option for trailers with electric brakes, and its wiring diagram is relatively simple and straightforward. By following the instructions and FAQs in this article, you can ensure a successful installation and worry-free towing experience.
