Technical Specifications and Compatibility
The CURT Discovery Time-Delay Brake Controller is specifically designed for the 2015–2019 Land Rover Discovery Sport. The controller is part of a comprehensive trailer hitch kit that includes a Class 3 trailer hitch with a 2-inch receiver, a 2-5/16-inch ball mount, a 4-inch drop bracket, and a 7-way trailer wiring system. The hitch has a gross trailer weight (GTW) capacity of 4,500 pounds and a tongue weight (TW) capacity of 675 pounds, making it suitable for a wide range of towing applications.
The brake controller itself is compatible with 12-volt negative ground systems and is intended for use with trailers equipped with two to eight brakes. It supports proportional braking, allowing the controller to adjust brake power in response to the vehicle’s speed and braking input. This dynamic adjustment helps reduce stress on the vehicle and trailer, improving overall safety and control.
The controller is also designed to work with low-voltage and PWM (Pulse Width Modulation) systems, ensuring compatibility with a variety of trailer configurations. It includes built-in protections such as reverse-polarity and short-circuit protection, as well as indicators for low voltage and trailer disconnect. These safety features help prevent electrical issues that could compromise the integrity of the braking system.
Installation Process and Required Components
The installation of the CURT Discovery Time-Delay Brake Controller is designed to be straightforward, thanks to the inclusion of a custom wiring harness and a quick plug system. The installation process typically involves the following steps:
Determine Mounting Location: The controller should be mounted in a secure, accessible location within the vehicle. The mounting area must be clear of any potential obstructions or sources of interference, such as CB radios or other RF transmitters.
Prepare Mounting Surface: The mounting bracket can be secured using either the provided screws or double-sided mounting tape. The front of the bracket must face the driver for proper orientation.
Mount the Controller: The controller is attached to the mounting bracket and secured in place. The mounting hardware included in the package ensures a stable and durable installation.
Connect the Wiring Harness: The controller is connected to the vehicle’s electrical system using the custom wiring harness. This harness is designed for plug-and-play installation, eliminating the need for splicing or soldering.
Test and Calibrate: Once installed, the controller should be tested to ensure it functions correctly. The digital display can be used to adjust power settings and ramp times according to the user’s preferences.
The installation process is further supported by detailed instructions, schematics, and diagrams included in the product package. These materials provide step-by-step guidance for users who may be unfamiliar with electrical installations or vehicle modifications.
User Interface and Operation
The CURT Discovery Time-Delay Brake Controller features a user-friendly interface that allows for precise control over trailer braking.

The controller also includes a pressure-sensitive manual override button, which allows for immediate application of brake pressure in any amount. This feature is particularly useful for correcting trailer sway or slowing the vehicle down quickly in emergency situations.
The controller’s interface includes the following key components:
- Digital Display: Provides real-time feedback on power adjustments and braking activity.
- Load Range/Calibration Button: Used to set the load range and calibrate the controller for optimal performance.
- Output Adjustment Thumb Wheel: Allows for smooth and precise adjustments to the power output.
- Manual Control Lever: Enables manual override of the braking system for immediate control.
These components work together to provide a responsive and intuitive user experience, ensuring that the driver can maintain full control over the trailer’s braking system at all times.
Safety Features and System Protections
The CURT Discovery Time-Delay Brake Controller includes several built-in safety features to protect both the vehicle and the trailer. These features are designed to prevent electrical faults and ensure the safe operation of the braking system. Key safety features include:
