The CURT Spectrum-2 Brake Controller is a fully compatible unit, able to operate up to eight trailer brakes at a time (1-4 axles). It can be used on vehicles with ABS brakes and cruise control and electric over hydraulic, and it works with low-voltage and PWM systems.

The interface of the Spectrum-2 Brake Controller is simple but powerful. It is a single rotary knob with a push-button in the centre that allows the driver to adjust brake power output. It is equipped with ten tri-colour 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.
