Brake Controls & Wiring Adapters

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 Pro Series Pilot controller has a dark, smoke lens that is ideal for direct light applications, creating optimum visibility to read the large, two-digit display. It also has flexible mounting options and can be installed in any direction. Our microprocessor allows you the ability to read the display even when mounted upside down. The Pilot’s digital display shows voltage output to the brakes.

Custom wiring adapter plugs into one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your GMC Sierra's dash.

Compatible with RAM 1500, 2500, 3500. These 2-Plug units are designed for brake controls that have a wiring port built into the back of the unit. Simply plug the brake control end of the wiring harness into the back of the brake control and the vehicle end into the automobile's port. Brake controls that utilize the 2-plug style of wiring harness will be identified with the Plug & Play logo.
