Ford Trailer Brake Controller Wiring Diagram

When towing a trailer, it is important that the trailer brakes are synchronized with the vehicle brakes. This helps to improve control and safety while towing. To achieve this, a brake controller is installed in the vehicle. In this article, we will discuss the wiring diagram for the Ford trailer brake controller.

What is a Ford Trailer Brake Controller?

A Ford trailer brake controller is a device that synchronizes the trailer brakes with the vehicle brakes. It is installed in the vehicle to help improve control and safety while towing a trailer. The brake controller works by sending electrical signals to the trailer brakes when the driver applies the vehicle brakes.

There are different types of Ford trailer brake controllers, including proportional, time-delayed, and inertia-activated controllers. Each type has its own unique features and benefits, but they all serve the same purpose of synchronizing the trailer brakes with the vehicle brakes.

Wiring Diagram for Ford Trailer Brake Controller

The wiring diagram for a Ford trailer brake controller is straightforward and easy to understand. It consists of four main components: the brake controller, the vehicle brake switch, the trailer brake switch, and the trailer connector.

The brake controller is the main component of the system. It is usually mounted in the cab of the vehicle and connected to the vehicle’s electrical system. The brake controller receives signals from the vehicle’s brake switch and sends signals to the trailer brake switch.

The vehicle brake switch is the switch that activates the vehicle’s brakes. It is usually located on the brake pedal or near the brake pedal. When the driver applies the brakes, the vehicle brake switch sends a signal to the brake controller.

The trailer brake switch is the switch that activates the trailer brakes. It is usually located on the trailer’s brake system. When the brake controller receives a signal from the vehicle brake switch, it sends a signal to the trailer brake switch to activate the trailer brakes.

The trailer connector is the interface between the trailer and the vehicle. It is usually located at the rear of the vehicle and connected to the vehicle’s electrical system. The trailer connector provides power to the trailer’s lights and other electrical components, including the trailer brakes.

Ford Trailer Brake Controller Wiring Diagram – Proportional Controller

A proportional controller is a type of Ford trailer brake controller that provides smooth and consistent braking. It applies the trailer brakes in proportion to the vehicle’s braking force. The wiring diagram for a Ford trailer brake controller with a proportional controller is as follows:

Wire color Description
Red 12V power
Black Ground
Blue Trailer brake output
White Vehicle brake input

The red wire should be connected to a constant 12V power source. The black wire should be connected to ground. The blue wire should be connected to the trailer brake output wire. The white wire should be connected to the vehicle brake input wire.

The vehicle brake input wire can usually be found near the brake pedal. It is usually a white wire with a red stripe. The trailer brake output wire can usually be found near the trailer connector. It is usually a blue wire.

Ford Trailer Brake Controller Wiring Diagram – Time-Delayed Controller

A time-delayed controller is a type of Ford trailer brake controller that applies the trailer brakes with a fixed delay after the vehicle brakes are applied. The wiring diagram for a Ford trailer brake controller with a time-delayed controller is as follows:

Wire color Description
Red 12V power
Black Ground
Blue Trailer brake output
White Vehicle brake input
Yellow Boost

The red wire should be connected to a constant 12V power source. The black wire should be connected to ground. The blue wire should be connected to the trailer brake output wire. The white wire should be connected to the vehicle brake input wire. The yellow wire is used to adjust the braking force and should be connected to the boost wire if your vehicle has one.

Ford Trailer Brake Controller Wiring Diagram – Inertia-Activated Controller

An inertia-activated controller is a type of Ford trailer brake controller that applies the trailer brakes based on the vehicle’s deceleration rate. The wiring diagram for a Ford trailer brake controller with an inertia-activated controller is as follows:

Wire color Description
Red 12V power
Black Ground
Blue Trailer brake output
White Vehicle brake input
Green Inertia sensor

The red wire should be connected to a constant 12V power source. The black wire should be connected to ground. The blue wire should be connected to the trailer brake output wire. The white wire should be connected to the vehicle brake input wire. The green wire is connected to an inertia sensor that detects the vehicle’s deceleration rate.
