Welcome to an entirely new towing experience. The Curt Echo brake controller puts you in control of your trailer's braking with mobile, Bluetooth operation.

Simple, Fast Setup
![Curt Echo Plug In Brake Controller]()
With no wiring, modules, or knobs to install, setting up the Curt Echo is a breeze. Just download the Echo Smart Control app on your Apple or Android smart device and follow the in-app instructions. The brake control unit plugs into the 7-way at the rear of your Chevrolet C/K Series Pickup and provides a port for plugging in your 7-way trailer connector. When all the connections are made, wirelessly pair the unit to your phone via Bluetooth. Once the unit is paired, configure your desired trailer brake settings in the user-friendly app.
See etrailer.com's exclusive 7-way upgrade kit for brake controller installation (ETBC7L - sold separately) if you don't already have a 7-way plug at the back of your Chevrolet C/K Series Pickup.
Echo Smart Control App
The Echo Smart Control app is free to download and use. Scan the QR code included with the Curt Echo or search Echo Smart Control in the Apple App Store or Google Play Store.
![Curt Echo Manual Control]()
The custom-designed app allows you to control brake settings, calibrate output, and monitor all braking activity with the touch of a finger. If ever there is a time that you need to brake your trailer separately from your tow Chevrolet C/K Series Pickup - when traveling down a steep incline, for example - the manual override function is easily accessible in the app. Press and hold the large orange circle to manually activate your trailer brakes.
The app will also alert you in the event that your trailer is overloaded or becomes disconnected during travel. Should your smart device ever lose connection, the Echo will default to the settings of the last profile used. So even if your phone battery dies, you can still count on getting proportional trailer braking as long as the unit is in use.
There's no need to worry about missing a call or running multiple apps either. The Echo Smart Control app will continue running in the background if you get a call or switch between apps, and it will not interfere with your Chevrolet C/K Series Pickup's hands-free multimedia system.
Create Multiple Chevrolet C/K Series Pickup-Trailer Profiles

The app has the ability to sync up to 5 Echo devices, and the memory function allows you to save unlimited Chevrolet C/K Series Pickup-trailer profiles. This makes it easy to transfer the Echo between towing setups. This convenience, along with the plug-and-play design, makes the Echo perfect for either occasional towing or commercial fleets.
Weatherproof Construction

Because the Echo is made to be outside the Chevrolet C/K Series Pickup, it's engineered for maximum weather resistance. The unit is filled with an epoxy resin that seals off the internal components from moisture and the elements, ensuring long-lasting operation despite rain, snow, dirt, mud, and more. The Echo also has a soft locking tab for connecting to your 7-way RV-style plug. This tab helps to reduce vibration and improve connectivity.
LED Status Indicator

A single LED on the body of the Echo shows the status of the brake control unit so that you can easily troubleshoot any problems that may arise.
Proportional Braking
With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow Chevrolet C/K Series Pickup. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.
Once the Echo is installed, it will sense - via an internal 3-axis accelerometer - how your tow Chevrolet C/K Series Pickup brakes. This inertia-based sensor responds to the deceleration of your tow Chevrolet C/K Series Pickup as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
