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. The portable unit installs in seconds and allows you to make braking adjustments straight from your smartphone. Easily transfer the Echo between vehicles and store it when it's not in use.

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 vehicle 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 vehicle.

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 vehicle - 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 vehicle's hands-free multimedia system.

Create Multiple Vehicle-Trailer Profiles

Vehicle Trailer Profiles

The app has the ability to sync up to 5 Echo devices, and the memory function allows you to save unlimited vehicle-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

Curt Echo Features Diagram

Because the Echo is made to be outside the vehicle, 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

Curt Echo Diagnostic 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 vehicle. 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 vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle 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.

I just got a new company vehicle that didn’t have a brake controller installed. I needed to make a trip on Monday morning with a 14 foot tandem axle work trailer. I ordered the controller Friday afternoon and it arrived Monday morning. I plugged it in and went through the setup in about 5 minutes and it worked perfectly. The easy installation and phone app control is exactly what I needed to make the trip on time!

2018 Chevrolet Silverado

Product works completely as described. Easy to add a controller to ANY vehicle that has a 7 point trailer plug like my 2018 Chevy Silverado (no factory brake controller but has a prewired 7 and 4 point trailer plug) or my 2014 Jeep Grand Cherokee. Trailer is a 2 axle CargoMate. App was a bit hard to find on the AppStore (iphone). Search "Echo" not Curt then it comes up. Set up is quick and easy to modify if necessary with load changes. App does not need to be normally running if you don't need to apply brakes manually. But if you do need to apply brakes, the response is surprisingly fast through the Bluetooth communication. No delay whatsoever. It doesn't interfere with other apps running either. I like to use navigation and stream music from my iphone 8. Only real issue I have with the product is that its not lockable. Very easy for someone who knows what they are looking for to just unplug and run. I parked overnight at a hotel and didn't realize it until the next day. Got lucky that it didn't get stolen, but now I'm aware and take it off when done towing.

Been a year and 1000s of miles of towing ... still working great!

2018 Toyota Echo

After owning the Echo Brake Controller for a year now, we were finally able to use it for a long distance trip this past March when we trailered two heavyweight motorcycles in an enclosed trailer from New Jersey to Florida. In a nutshell, it worked perfectly. The app is easy to use and the directions are simple. The Echo syncs up right away to your phone's bluetooth and once underway, adjustments can be made quite easily. I have a new car and the last thing that I wanted to do was drill holes in my dashboard to mount an older, wired unit. I read about this echo control, however, I was very skeptical about the technology, as was my trailer hitch guy. Therefore, I called etrailer before buying the Echo. I don’t recall who I talked to, but he fully explained the technology, including the fact that once the trailer and echo were connected, I could toss my phone out the window and the controller would still work because it remembers and maintains its last setting and does not need to be synced to a phone to operate. I took a leap of faith and placed the order. I’m pleased I did. I highly recommend the Echo Brake Controller.

I remain very pleased with the Echo brake controller. It’s very easy to use and I’m confident that it will continue to function perfectly. As others have stated the locking mechanism does not always feel totally engaged. Therefore, I devised a strap that holds it tight in the socket. I highly recommend the Echo brake controller.

I have used this controller to travel cross country, even in inclement conditions. It has one crack in the housting, but it works great. I also like the phone app.

My daughter ordered a Curt Echo Wireless Brake Controler from another dealer and it appeared to be faulty. I contacted eTrailer to confirm my diagnosis and they were very helpful and confirmed that the controller was faulty. As we were in a time crunch to get the trailer brakes operational, I ordered a new controller from eTrailer and it worked as advertized - easy setup and control plus three families can use the same controller instead of having to have 3 separate controllers. Only issue is that it took over a week for them to ship the controller even though they showed it in stock when I ordered it.

2011 Ram 1500

I purchased this product for use with my travel trailer(the folks at etrailer shipped it really fast) as my new truck didn't come with one and I didn't want the hassle of installing a wired one, and wasn't wild about having something else under the dash. The setup was very easy. The app downloaded quickly on my phone and paired immediately with the controller. I double checked that the braking function on the phone was actuating the trailer brakes (it was). I haven't pulled my trailer with it yet,but my initial impressions are that it is good quality, is easy to use, and so far has done everything as advertised. I woulf recommend watching etrailer's instructional video on YYoutube.

This wireless trailer brake controller works as described. I am extremely satisfied with this purchase. I would highly recommend the Curt Echo to anyone who doesn't want to hard wire a brake controller in there vehicle.

- C51180

When towing, there are times you need to stabilize the trailer by tapping the trailer brake only. The only way to do that with this controller is via an app on your phone or tablet. I don't know about you, but my phone always seems to be doing stupid things when I need it. Maybe a smarter person could get it to work reliably, I can't use it.

- C51180

This product is great. I really like that I can have one trailer brake controller for several trailers/vehicles.

Great! We really like the portability and that we didnt need to install brake controllers in each vehicle.

Good results and easy to use I would recommend it to anyone who wants to pull a trailer and doesn't want to put a controller on their dash, it's much easier and faster

Hank L - 04/16/2021

This is by far the only way to go to install electric trailer brake system on your vehicle! It is extremely easy to install on the vehicle and download their app on your phone and that way there is nothing inside your vehicle to mess with! It runs off of Bluetooth and you can have five or six vehicles programmed into it so you can switch different vehicles around with different trailers and just log into the app and pick the one that you are using at that time and put it in the settings that work for that trailer and vehicle on your phone app and you are ready to go. If you start driving and decide that the trailer brakes need to be changed all you do is open your app and change the settings on the app so that you have proper braking on the trailer and you can also just push the center on the app to apply the trailer brakes without applying the vehicle brakes. This is the only trailer braking system I will be using for the foreseeable future.

- C51180

The cost of this device alone was less than wiring a fixed device in my Jeep Wrangler JL. There is no need for a controller in the cab that is in the way especially when you are not towing. It has worked flawlessly. Disregard negative reviews from those who don’t understand Bluetooth devices. This thing works. I wish there was a way to lock it on the vehicle but so far I’ve had no issues with theft.

Perfect. I have recommended it to many on the JL Jeep forum.

Unfortunately this controller was not usable for me. I set it up as a controller in my motorhome for my tow dolly brakes. The distance between the drivers seat and the hitch connection was about 35 ft and the signal between the controller and android phone was too weak to maintain a constant usable signal that would allow me to manually activate brakes if needed. Curt could not offer a solution.

- C51180

Performs as advertised--Overall I'm impressed with the product and this may be the future of controllers. It enabled me to use my trailer brakes without hard-wiring a controller into my car. Only a couple of concerns... -Unfortunately there's no way to secure it if you park/leave your vehicle connected in a parking lot. -And I was unable to get the function on the app to turn on my flashers while assisting someone along side the road.

Dodge Ram Pickup

PROS: In my Tacoma there is really not a good place to mount a controller that is easy to see. Since this product uses my iPhone I can (using a ram mount) put it anywhere I want. Best visibility of any brake controller I have ever used. Button for applying trailer breaks manually works much better than I expected. Very easy to set up. CONS: 1. Minor gripe, since this unit rides outside your truck it needs to be tough, the plastic that it is made of seems like it would not survive much in the way of impact. 2. The unit does not fit snuggly in my standard Tacoma 7-pin receptacle. Added a single layer of duct tape around the circumference to resolve.

Use it once or twice a month on average. Seems to be holding up just fine.

Toyota Echo

When I purchased my new vehicle, I had trouble finding a convenient location under the dash to mount my old brake controller. The Echo solved the problem. It just plugs in to 5 pen connector. I have used it with two different trailers. It stores your settings and the intensity and sensitivity controls have worked great. It was easy to set up. I have recommended it to friends, the vehicle dealer and to the brake/'trailer shop where I do business.

Toyota Echo

I was a little nervous about this, but after reading the instructions and staying calm, I realized this was a great purchase. I did not want to have to install an under-dash controller and mess with wires, etc. CURT Echo Bluetooth technology has solved all that. It syncs up easily every time I use it. This little gem has great flexibility in setting the brake sensitivity and power just the way you want it. I can change vehicles anytime I want and the ease of hooking it all up is indisputable. I couldn't be happier. Thanks CURT ECHO!!

- C51180

It worked great at first then it started disconnecting from the phone and then would just lock my brakes up on the trailer every time I touched the petal. I ended up getting a Tekonsha hired wired controller! Thanks

- C51180

Took it for an 800 mile shakedown, hauling a new travel trailer back from Georgia with my Jeep Gladiator. Easy to set up, easy to activate, and easy to use. Worked like a charm. Even better- The trailer dealership mechanic highly recommended this specific controller and tried to sell me one; not knowing I’d brought one with me!

- C51180

I do not use with my phone. I purchased because a local shop quoted me $500 to install a brake controler on my RV. And I also needed one on my Toyota 4Runner. Well for the price of this unit, which I keep handy for both vehicles - I'm not ready. Purchased a 16 foot enclosed trailer 7.5K pound rating with duel axles and it works great. Only one axle has the electric brakes. I dont believe my unit had teh rubber strap, so I just use a zip tie. I keep them (short/long ones) in my tool box.

- C51180

I will not purchase anymore. Hard to use and disconnects from your phone. Having all of my clients hardwire dash units instead. The Curt brake controller had a hard time hooking up to my clients truck. It kept dropping its blue tooth signal while driving. It fell off while driving too. I build go everywhere off road trailers. Not a good thing for it to loose connection descending a steep trail. I had to pay for my client to hard wire a brake controller for his 4runner. Lesson learned. At least I gave it a try. Everything else I have bought and will continue to buy is awesome.

- C51180

This is a convenient way to have a brake controller on multiple vehicles. It works very well. We have used it on about 1500 miles of pulling a 30-foot camper with a Jeep Grand Cherokee and it easily controlled the brakes and trailer. I have recommended this brake controller to others.

- C51180

Almost EXCELLENT, small problem; won's stay inserted into the 7way socket. I've emailed etrailer and asked if this is a common problem, I'm sure they'll either have a solution or I'll come up with a strap of some sort. Fortunately ours is a 5th wheel and the connector is in the bed. If it was off the bumper it'd be a bigger problem for sure!! But he controller works great, easy to set up and I don't think I'll hit my leg on it.

Perfect after a year, very pleased with purchase!

I ordered eco trailer brake system...it was a better price than any were else I looked. Once I received it wich was faster than they said it would be, however I thought I was missing a part. I contacted them and they led me to were the rest of the product was that I had the whole time. I will buy anything I need from them in the future for sure!! I can't say enough how pleased I was. Thanks etrailer...

- C51180

Bottom line based on my experience with Curt. Do not buy. Purchase this brake controller and wasn't able to use it for several months and when I finally did, the controller didn't work. Contacted Curt to remedy the problem and no help whatsoever. I ended up purchasing the Tekonsha P-3 Proportional controller and love it. I would not buy a Curt product again and think twice before spending $xx.xx on the Echo Wireless.

  • Comparing the Universal Installation Kit # ETBC7 and the 7-Way RV Upgrade Kit # ETBC7L
    There are a few differences between the Universal Installation Kit part # ETBC7 and the 7-Way RV Upgrade Kit part # ETBC7L. The biggest one is that part # ETBC7 comes with both the power and brake output wire you will need to run to the cab/battery whereas the part # ETBC7L only comes with the power wire you will need to run to the battery. The reason for this is because part # ETBC7L is geared more towards wireless brake controllers like the Curt Echo Mobile Trailer Brake Controller part...

For example, if you used a 4-to-7 way adapter such as # 30717, there will not be an output wire from the Echo to connect to, so you could simply tie that wire off, as you can see by the accompanying diagram.

  • Can Brake Controller be Installed on a 2020 Tesla Model 3
    It is possible to connect a brake controller to your 2020 Tesla Model 3.

  • How To Wire Brake Controller and 7-Way Plug In 2020 Hyundai Palisade
    The Prodigy P3 Brake Controller part # 90195 needs to be wired to the cold side of the brake light switch which is normally located near the brake pedal.

  • Parts Needed to Install Curt Spectrum Brake Controller in 2020 Jeep Gladiator
    We have an easy way to install the Curt Spectrum in your 2020 Jeep Gladiator but the install harness you mentioned was designed for the Ram trucks and would not fit your Gladiator. So the harness you would want is the part # 3073-P which the gray end will plug into the factory connector on your Jeep and once you cut off the black connector will wire color for color to the wiring of the Spectrum # C51170. At this time (April 2020) there isn't a harness from Curt that fits your Gladiator.
