The CURT Spectrum trailer brake controller gives you powerful, precise braking operation in an extremely simple and subtle design inside your vehicle. It features an LED-equipped, rotary knob interface and a separate main module with an advanced accelerometer. This allows for an OE look and feel to be maintained inside the cab of your vehicle. The separated design of the Spectrum brake control allows the main module to be mounted behind the dash of the vehicle, completely out of sight. Meanwhile, the compact, unobtrusive interface can be fully integrated into the dash with just a single hole.

The interface of the Spectrum trailer brake controller is simple but powerful. It is a single rotary knob with a push-button in the center that allows the driver to adjust brake power output. It is equipped with ten tri-color LEDs (red, blue, and green) to show the automated power output of the control. There is no need for a separate display or additional controls, keeping the dash of your vehicle clean, professional, and uncluttered.

Behind the Spectrum brake controller is a powerful main module with a triple-axis motion-sensing accelerometer. This advanced circuit can detect the inertia of the vehicle and trailer on all axes of three-dimensional space. Whatever your speed and whatever grade you are travelling on—up hill or down--the Spectrum brake control produces the exact amount of power needed for a smooth, safe stop every time. The main module can be mounted with the included mounting brackets or adhesive patch.

The Spectrum electric brake controller is a fully compatible unit, able to operate up to eight trailer brakes at a time. It can be used on vehicles with ABS brakes and cruise control, and it works with low-voltage and PWM systems. It installs in ten minutes or less, using a quick-plug harness that is vehicle-specific and plugs into any CURT brake control for a custom-fit installation in the vehicle. The Spectrum also has automatic leveling and calibration features to simplify the setup process.
