Adjustment Options

Within the intricate landscape of a wiring diagram for a Tekonsha Trailer Brake Controller, adjustment options emerge as a critical aspect, empowering users to tailor the controller’s behavior and optimize trailer braking performance. These adjustable settings, such as gain and boost, provide a means to fine-tune the controller’s response to varying trailer weights, road conditions, and personal preferences.

Gain Adjustment

Gain adjustment allows users to calibrate the sensitivity of the controller. By increasing the gain, the controller becomes more responsive to the vehicle’s brake pedal input, resulting in a more aggressive braking action from the trailer brakes. Conversely, decreasing the gain reduces the controller’s sensitivity, making the trailer brakes less responsive.
Boost Adjustment

Boost adjustment enables users to enhance the initial braking force applied by the trailer brakes. This is particularly useful when towing heavy trailers or when encountering slippery road conditions. By increasing the boost, the controller applies a greater initial braking force, helping to reduce stopping distances and improve overall trailer stability.
Proportional Braking

Proportional braking ensures that the braking force applied to the trailer brakes is proportionate to the braking force applied to the vehicle’s brakes. This helps to maintain a balanced and stable braking system, preventing the trailer from pushing or swaying excessively.
Anti-Sway Control

Anti-sway control is a feature found on some Tekonsha Trailer Brake Controllers that helps to mitigate trailer sway. It works by applying the trailer brakes on one side of the trailer when it detects excessive movement, effectively countering the swaying motion and restoring stability.

Understanding and adjusting these settings is essential for maximizing the effectiveness of a Tekonsha Trailer Brake Controller.
