The ECHO 51190 is an under-dash trailer brake controller that manages trailer braking through a mobile app via Bluetooth connection. It allows you to control trailer brakes automatically during vehicle braking or manually via the app's orange button. The unit mounts under the vehicle's dash and connects to the vehicle's battery and 7-way trailer connector.
The ECHO 51190 is designed for tow vehicles equipped with a factory brake control plug or that can accommodate the CURT universal brake control wiring kit #51500. Most trucks and utility vehicles have a factory plug. Check your vehicle owner's manual for plug availability and location. If your vehicle does not have a factory plug, you can use the CURT universal wiring kit #51500. For specific vehicle compatibility, see the CURT catalog or visit curtmfg.com.
If your vehicle does not have a factory brake control plug, CURT recommends purchasing the CURT universal brake control wiring kit #51500. Alternatively, you can use the CURT quick plug harness #51515 or #51516 with pigtails, though hard wiring will be necessary if the harness is unavailable. Check the CURT catalog or curtmfg.com for application information.
No, the ECHO 51190 is not compatible with Apple CarPlay or Android Auto. However, it will not interfere with these features. The ECHO controller operates through the separate OneControl® Auto mobile app, which must be downloaded from the App Store or Google Play.
The ECHO 51190 package includes: one main module, one main module adhesive pad, and four 8-inch zip ties. Additional wiring components such as a brake control harness, CURT quick plug harness, or CURT universal brake control wiring kit #51500 may be needed depending on your vehicle's factory equipment.
The manual specifies that a small pointed tool is needed to adjust the two switches located at the front of the unit. For wiring installation, you will need tools to work with 10-gauge and 10/12-gauge wires, ring terminals, and butt connectors. The manual does not specify other tools required for mounting or general installation.
Yes. Disconnect the tow vehicle's negative battery terminal from its battery post before beginning the installation process. This is a required safety step before any wiring work.
Mount the main module securely to a solid surface under the dash. The orientation of the module does not matter. The module should be easy to access for troubleshooting but can be installed out of sight to reduce contact with the operator. The module must be mounted firmly in place to prevent improper operation and brake failure. Do not mount it near the exhaust pipe, as this may result in heat damage, loss of functionality, and risk of fire.
Yes. Avoid mounting the brake control module near a CB radio or other RF transmitter, as this may cause interference. Also, do not mount the ECHO near the exhaust pipe, as failure to do so may result in heat damage, loss of functionality, and risk of fire.
Secure the module in place using the provided adhesive pad and the four 8-inch zip ties. First, determine a suitable mounting location under the dash on a solid surface. Then apply the adhesive pad and use the zip ties to ensure the module is firmly mounted.
1. Mount the 30-amp auto-reset circuit breaker as close to the battery as possible. 2. Insert two 10-gauge wires (one white, one black) from the mounted brake control to the battery area. 3. Using a ring terminal, connect the black wire to the 'AUX' side of the 30-amp circuit breaker. 4. Using a 10/12-gauge butt connector, attach the black wire from the 'AUX' side of the circuit breaker to the brake control's black wire. 5. Using a 10/12-gauge butt connector, attach the white wire from the battery area to the brake control's white wire. 6. Run a 10-gauge blue wire from the tow vehicle's trailer plug 'BRAKE' terminal to the brake control. 7. Using a 10/12-gauge butt connector, connect this blue wire to the brake control's blue wire.
The main module's positive (with 30-amp circuit breaker) and ground wires must be connected directly to the tow vehicle's battery using a minimum of 10-gauge stranded wire. Connecting to existing wiring or an alternate ground may damage the vehicle's circuits, lead to failure of the brake control module, loss of trailer brakes, or vehicle fire.
When passing wires through sheet metal, always go through an existing grommet. If there is no grommet, install one or use silicone sealant to protect the wires from sharp edges. This prevents damage to the wiring and potential electrical hazards.
Mount the 30-amp auto-reset circuit breaker as close to the battery as possible. This is a critical safety requirement for the ECHO 51190 installation.
Yes. There are two small switches located at the front of the unit next to the port. You should set these switches before mounting the module. Switch #1 (left) controls brake light activation; the factory default is 'ON' (down position), which activates brake lights when manual control is used. Switch #2 (right) controls manual control output level; the factory default is 'ON' (down position), which limits output to the level set by the output control. Use a small pointed tool to adjust these switches.
The 10-gauge blue wire runs from the tow vehicle's trailer plug 'BRAKE' terminal to the brake control. It is connected to the brake control's blue wire using a 10/12-gauge butt connector.
The black wire is the power wire. It connects from the battery through a 30-amp circuit breaker to the brake control's black wire using a 10/12-gauge butt connector. The white wire is the ground wire. It connects from the battery area to the brake control's white wire using a 10/12-gauge butt connector. Both wires are 10-gauge stranded wire.
The ECHO 51190 is designed to provide a Bluetooth connection without obstructions up to 50 feet. Connection may also be limited by the Bluetooth signal of your device.
For Apple devices: iOS 14 or higher is required. For Android devices: Android 9.0 or higher is required. Bluetooth must be enabled on your device for pairing to occur. The OneControl® Auto app must be downloaded from the App Store or Google Play.
1. Enable Bluetooth in your mobile device settings. 2. Download and open the OneControl® Auto app from the App Store or Google Play. 3. Follow on-screen prompts, agree to the end user agreement, and complete initial registration. 4. Select 'Pair Device' under the ECHO brake icon on the home screen. 5. Grant location permissions to the app and enable device location. 6. The app will scan for the ECHO device. Once 'Echo® Brake Controller' appears, select it and tap 'Connect'. 7.

Once pairing is complete, you will receive a pairing successful notification and the LED light on the ECHO device will be solid blue. Note: Pairing happens within the app, not in the smartphone's Bluetooth settings menu.
If the LED on the ECHO under-dash is red at any moment during setup, stop and refer to the 'Troubleshooting Guide' on page 8 of the manual. A solid red LED indicates a hardware fault, and a flashing red LED indicates a wiring error.
Avoid distracted driving and only make adjustments when the vehicle is stationary. Adhere to all applicable traffic laws and motor vehicle safety regulations, including all laws prohibiting the use of handheld devices while operating a motor vehicle. The OneControl® app must be operating in the foreground of your cell phone applications; operating it in the background may cause delays in braking response when using the manual override button. Perform test drives and adjustments in a safe environment such as a parking lot or minimal traffic area.
Prior to driving, test all trailer lights while the trailer is plugged into the ECHO. This ensures that the brake controller is properly connected and functioning before you operate the vehicle.
The vehicle needs to be running or the ignition in the 'ON' position with the vehicle in park during initial setup. Perform tests and adjustments in a safe environment such as a parking lot or minimal traffic area. Starting with output adjustment, drive forward on a dry and level paved or concrete surface. At approximately 25 mph, apply the vehicle's brakes. If trailer braking is insufficient, increase the max output setting in the OneControl® app. If the trailer brakes lock up, decrease the max output. Repeat until stops are firm, just short of lock up. Once output is set, adjust sensitivity by driving at approximately 25 mph and pressing the brake pedal. The vehicle and trailer should make a smooth stop. Increase sensitivity if more aggressive braking is desired; decrease if the stop seems too aggressive. Make several stops at various speeds and adjust until stops are smooth and firm.
Output and sensitivity adjustments should only be made while stopped, with the transmission in park or neutral, parking brake applied, foot off the brake pedal, and no manual control actuation. Never make these adjustments while driving.
Flashing blue: Device not paired, no trailer connected. Solid blue: Device paired, no trailer connected. Flashing yellow: Calibrating ECHO. Flashing green: Device not paired, trailer connected. Solid green: Device paired, trailer connected. Flashing red: Wiring error. Solid red: Hardware fault. No light: No power.
The test drive and adjustment process must be repeated if there are any changes to weather or road conditions or significant changes in trailer weight or towing setup. This ensures the brake controller is properly calibrated for the current conditions.
Setting configuration is required when trailer conditions change or if the brake controller is being used for a different trailer or vehicle. You can create and save profiles for multiple vehicles, trailers, and load conditions in the OneControl® app. When conditions change, adjust the max output and sensitivity settings accordingly and perform a new test drive to ensure proper braking performance.
Manual brake activation allows you to apply the trailer brakes independently of the vehicle's brakes. Press and hold the orange button in the OneControl® app to activate manual braking. This is used in situations where a slow reduction in speed is desirable. As the manual control is activated, the ECHO begins to apply the trailer brakes. The orange outer ring in the app indicates the current brake output level.
The max output setting establishes the maximum amount of power available to the trailer brakes when braking. The output should be adjusted during initial setup, when trailer load changes, when different trailers are used, or when adjustment is needed for changing road or driving conditions. Adjust by tapping the maximum output button in the app and increasing or decreasing using the '+' or '–' buttons. The orange outer ring is a visual indicator of the current level of power being applied to the trailer brakes.
The sensitivity level adjusts the aggressiveness of trailer braking when activated during vehicle braking. Sensitivity adjustment has no effect on the manual brake control. The sensitivity can be adjusted for individual driver preference, trailer load changes, or changing road conditions. Adjust by tapping the sensitivity button in the app and increasing or decreasing using the '+' or '–' buttons. Increase sensitivity for more aggressive braking; decrease for smoother braking.
When the vehicle's hazard lights are activated, the trailer brakes may pulse on and off as the lights flash. To prevent pulsing brake output, toggle the vehicle hazard lights switch ON in the app any time the vehicle's hazard lights are active. This prevents unwanted brake pulsing during emergency situations.
Yes. You can create and save profiles for multiple vehicles, trailers, and load conditions. In the OneControl® app, select the '+' symbol in the orange controller profile menu to add a new profile. You can modify the description of your vehicle and trailer, and you can switch between different profiles by swiping left or right on the active controller profile on the home screen. The five most recently used settings are stored within the ECHO device.
You can switch between different profiles by swiping left or right on the active controller profile on the home screen. Once the chosen profile is set to active, select 'Open' under the connected ECHO device to activate it.
To modify a profile: Select the profile you would like to edit by swiping left or right. Select the pencil or 'edit' icon next to the tow vehicle or trailer icons to enter settings. Change the respective tow vehicle name or trailer name and select 'OK'. To delete a profile: Select the profile by swiping left or right, select the pencil or 'edit' icon, select 'Delete Profile', and select 'OK'.
The ECHO 51190 works with tow vehicles equipped with a factory brake control plug or the CURT universal wiring kit #51500. Check your vehicle owner's manual for plug availability, or visit curtmfg.com for specific compatibility.
The package includes the main module, adhesive pad, and four 8-inch zip ties. You may need additional wiring components such as a CURT quick plug harness or universal wiring kit #51500 depending on your vehicle.

Use a minimum of 10-gauge stranded wire for power and ground connections directly to the battery. Use 10/12-gauge butt connectors for wire connections. Do not connect to existing wiring.
You need a smartphone with iOS 14+ (Apple) or Android 9.0+ (Android) and Bluetooth enabled. Download the OneControl® Auto app from the App Store or Google Play.
Test all trailer lights while the trailer is plugged into the ECHO before driving. Perform initial brake testing at approximately 25 mph on a dry, level paved surface in a safe environment.
Solid blue = paired, no trailer. Solid green = paired, trailer connected. Flashing red = wiring error. Solid red = hardware fault. No light = no power. Refer to the troubleshooting guide if the LED is red.
Check vehicle power and ground wiring. Verify that the negative battery terminal is properly connected and that the 30-amp circuit breaker is mounted close to the battery. Some vehicles require a trailer to be connected to activate 7-way power. If a trailer is not available, the CURT 7-way tester #58272 may be used to complete setup and troubleshooting.
First, check the ECHO LED status for power. Verify that Bluetooth is enabled on your smartphone and that location permissions are granted to the app. Confirm that you are entering the correct six-digit PIN from the label or quick reference card. Check smartphone compatibility (iOS 14+ or Android 9.0+). If the issue persists, reset the Bluetooth connection by selecting the trailer profile, tapping the ECHO device name, then tapping the trash can icon to remove it. In your phone's OS Settings, go to Bluetooth connections and 'forget the device', then re-pair.
A solid red LED for more than 10 seconds indicates a hardware fault. Contact CURT Product Support. They will need the serial number located on the label of your unit.
A flashing red LED indicates a wiring error. Check for contamination or moisture in the trailer plug socket and ensure it is clean and dry. Locate and correct any short in the trailer brake wiring. If the issue is an accelerometer error, unplug the brake controller and plug it back in. If there is a short or overload in the trailer brakes, troubleshoot the trailer brake circuit per the brake manufacturer's instructions.
Check for the following issues: Mis-wired 7-way connector, improper or corroded trailer wiring, or weak or missing ground. Confirm that both the vehicle and trailer 7-way connections are correct. If the app signals 'disconnect', the trailer connection may be unplugged or have bad wiring. Verify all connections are secure and clean.
Check for the following issues: Mis-wired 7-way connector, improper or corroded trailer wiring, no or intermittent power to the controller, weak or missing ground, or wireless connectivity error. Confirm that both vehicle and trailer 7-way connections are correct. Check Bluetooth and application settings. Ensure the OneControl® app is operating in the foreground of your cell phone applications.
Check for the following issues: Weak or missing ground, improper max power or sensitivity settings, or improper or corroded trailer wiring. Confirm that both vehicle and trailer 7-way connections are correct. Check Bluetooth and application settings. Increase the max power or sensitivity settings in the OneControl® app to achieve the desired braking performance.
This indicates a mis-wired 7-way trailer connector. Confirm that both the vehicle and trailer 7-way connections are correct. Review the wiring diagram on page 3 of the manual to ensure all connections match the proper configuration.
Low voltage indicates that the vehicle battery voltage is low. Check the vehicle battery and replace it if needed. Also confirm that the vehicle 7-way connections and wiring are correct and secure.
