The Curt Echo under-dash is all about simple use and easy install. With the main unit mounted out of sight beneath the dash, all you need is your smartphone to control the settings on the brake controller. You won't have to worry about banging your knee on a bulky controller, cluttering up your dash, or ruining the sleek look of your interior.

Control Your Towing with Your Smartphone and an App

The Echo is unique for giving you control of your towing through your smartphone. You can set the maximum braking output, adjust the braking sensitivity, apply the manual override - all from the OneControl app.

The Echo connects to the app via Bluetooth. You can save multiple trailer profiles in the app, a big plus if you have a fleet and want to be able to just select a pre-set configuration and get towing. And don't worry: after you've downloaded the app, you don't need to have data on to use the app with the brake controller. You'll be able to receive calls and texts and access your other apps.

User-Friendly OneControl App

Simple, intuitive, and user-friendly, the OneControl App makes it wicked easy to manage your settings and control your trailer.

1. Manual Override

This big orange button in the middle of the app is your manual override. Press and hold the button, and the brake controller will smoothly apply the trailer brakes without applying your vehicle's brakes. This is perfect for stopping sway or controlling your trailer's momentum in an emergency.

Quick tip; Put manual override right at your fingertips by adding this button (C83HR - sold separately) to your dash. The app must be running for the button to work, but it can be in the background while you use other apps on your phone. The button has an adhesive pad for a quick-stick installation and includes an easily replaceable battery.

2. Brake Output Indicator

The outer ring gives you a visual indicator of how much power is being applied to the trailer brakes. This is determined by your max output setting.

3. Max Output

Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop.

To set your maximum braking output, tap this button and increase or decrease using the + and - buttons. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust the settings until the trailer load changes, you switch trailers, or road conditions change.

4. Sensitivity Level

This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the max output level. This is a great adjustment to make when you're towing a heavy load and the trailer will need more umph to bring it to a stop so it doesn't push your vehicle forward.

Just like max output, if you need to change your sensitivity level, use the + and - buttons. If your vehicle takes too long to come to a stop, increase the setting. If it stops too abruptly, lower the setting. You may also need to adjust the sensitivity based on your own preferences, or when the trailer load or road conditions change.

5. Vehicle Hazard Lights

If you turn on your vehicle's hazard lights, there's a chance the trailer brakes will pulse on and off as the lights flash. Turn this setting on any time you activate your hazard lights to prevent this problem.

Save Multiple Trailer Profiles

Get on the road faster by saving your settings. With the app, you can add and store multiple profiles for both trailers and vehicles so that your preferred settings will be ready to go as soon as you hook up. This is perfect if you own a fleet and don't want to have to reset the controller every time you swap out trailers. You'll have the ideal settings saved and waiting for you. To switch between profiles, just swipe left or right.

OneControl: One-Stop App for Towing

If you like the idea of monitoring your trailer from your phone, the other OneControl systems could be a great fit for you.

The Curt True Course (C94VV - sold separately) is an advanced Bluetooth sway control system that automatically triggers the trailer brakes (independent of the vehicle's brakes and the brake controller) when it detects dangerous trailer movement. The Curt Tire Linc (C54VV - sold separately) Bluetooth TPMS monitors the temperature and pressure of your trailer tires. All of these systems use the OneControl app so you can manage all of them in the same place on your phone.

Simple, Out-of-the-Way Installation

You won't be dinging your knee on a bulky brake controller or interfering with your vehicle's lower airbags because the main unit mounts out of sight under your dash. This product comes with an adhesive pad and 4 zip ties to make it easy to mount anywhere. (Just don't zip-tie the box to wiring or cables that can shift as you drive!) Thanks to the 3-axis accelerometer, the main unit can be positioned at any angle. No matter how you install it, the unit will sense the direction of travel and deliver smooth, even braking.

The easiest way to install this brake controller is to get a custom, vehicle-specific adapter (sold separately) that plugs right into both your vehicle and the main unit - no hardwiring required. Otherwise you'll have to get a univeral harness and potentially splice into your wiring.

Note: If a custom brake control wiring adapter is not available for your vehicle, a 30-amp circuit breaker (sold separately) may be required for installation.

That done, download the OneControl app on your Apple or Android smartphone and wirelessly pair the unit to your phone via Bluetooth, following the in-app instructions. It should take about 5 seconds for them to pair. Once paired, the LED light on the unit will turn a solid blue. Plug in your trailer's 7-way and let the whole system calibrate for another 5 seconds. When the LED turns green, configure your desired trailer brake settings and save it as a profile. Then you're ready to tow!

Proportional Braking

The Curt Echo under-dash brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.

The Echo under-dash uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to ensure that your trailer slows at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Installation of Curt Brake Controller Adapter

To install your Curt electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.

This adapter plugs into the port on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.

No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.
