Big Tex Trailer Brake Wiring Diagram

If you own a Big Tex trailer, it is important to know how to properly wire the trailer brakes. Trailer brakes are essential for safety when towing heavy loads. In this article, we will discuss the Big Tex trailer brake wiring diagram, including how to connect the wires and troubleshoot any issues.

What is a Big Tex Trailer?

Big Tex is a leading manufacturer of trailers for a variety of purposes, including hauling equipment, livestock, and cargo. Their trailers come in different sizes and configurations to meet the needs of different customers. When it comes to towing heavy loads, having trailer brakes is crucial for safety, and Big Tex trailers come equipped with electric brakes.

Electric Trailer Brakes

Electric trailer brakes work by applying pressure to the brake drums when the trailer’s brake controller sends an electrical signal. The brake controller is connected to the tow vehicle’s brake system and sends signals to the trailer brakes when the driver applies the brakes. The amount of braking force applied to the trailer brakes can be adjusted to suit the load being towed.

Wiring the Trailer Brakes

Wiring the trailer brakes on a Big Tex trailer is a straightforward process. The trailer’s braking system consists of two main components: the brakes and the brake controller. To wire the trailer brakes, you will need to connect the brakes to the brake controller.

Wire Color Function
White Ground
Black Battery (power)
Blue Brake controller output
Red Brake light input

The white wire is the ground wire and should be connected to the trailer frame. The black wire is the battery wire and should be connected to the positive terminal of the trailer battery. The blue wire is the brake controller output and should be connected to the brake controller’s output wire. The red wire is the brake light input and should be connected to the tow vehicle’s brake light wire.

Common Issues with Trailer Brakes

Like any other part of a trailer, the brakes can sometimes malfunction or fail. Here are some common issues with trailer brakes and how to troubleshoot them.

Brakes Not Working

If the trailer brakes are not working, the first thing to check is the connections. Make sure all the wires are properly connected and there are no loose or broken connections. Also, check the brake controller settings and adjust them if necessary to ensure the proper amount of braking force is being applied.

Brakes Overheating

If the brakes are overheating, it could be due to a few different reasons. One common cause is the brakes being adjusted too tight. If this is the case, adjust the brakes so they are not as tight. Another possible cause is a faulty brake controller. If you suspect the brake controller is the issue, have it checked by a professional.

Brakes Making Noise

If the brakes are making noise, it could be due to worn brake pads. Check the pads and replace them if necessary. Also, check the brake drums for any signs of wear or damage. If the drums are worn or damaged, they may need to be replaced.

Conclusion

Wiring the trailer brakes on a Big Tex trailer is a simple process, but it is important to do it correctly to ensure safety when towing. By following the wiring diagram and troubleshooting common issues, you can be sure that your trailer brakes will work properly when you need them the most.
