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.

Video Transcript for Curt Echo Mobile Trailer Brake Controller Review

Speaker 1: Today we're going to be taking a look at the Curt Echo. This is a proportional wireless trailer brake controller. It's designed to work with one, up to two, axles. Part number is C51180. Now the Curt Echo it really changing the game when it comes to brake controllers. Basically, we are no longer required to install a bunch of wiring inside of our vehicle.

Or if we didn't want to do that, we'd have to install or permanently mount something on our trailer. In this case, we're basically going to plug this right between a working 7-pole and the wire on our trailer, sync it up with an app, and we have full wireless control. We can adust our gain. We can adjust the sensitivity, and we can store several different profiles for several different trailers.Now this type of controller is going to be great in a lot of applications. It's designed to work with trailers that have one or two axles, so four total brake assemblies.

But just imagine rental areas that rent equipment on trailers. A lot of customers aren't going to have that brake controller installed. This is going to allow them to safely haul that load. Also, fleet companies .. Maybe you've got six trailers and four different trucks, and each truck pulls a different trailer at a different time, or you don't want to go through the expense of adding a brake controller into each truck.

This can very quickly and easily be switched from vehicle to vehicle or trailer to trailer with no issues. I also see this being used a lot for the more complex wiring situations that we run into with our higher end or multiplex style wiring.Also, if you just don't want to put holes in your dashboard, you don't want to adjust or modify anything in the vehicle, this is going to give you the perfect solution. So there's a lot of different areas where this brake controller is really going to shine. Now the nice thing about the Echo is that it is a proportional brake controller. So now we're traveling.

We're just going to lightly hit our brakes. And see our brakes are applied just in that light affect. Now we'll go around the corner here. We'll hit our brakes a little harder once we get around, and we'll see what it does there. Once we get into this more of an emergency stop situation, you notice we've got much more brakes being applied and much more quickly. Now if we go to our sensitivity, if we don't feel like those are coming on quick enough, we bump that up just a little bit, hit our brakes again, and you can kind of fine tune it to get the feel that you're looking for.The benefit to that over a time delayed system is that you don't have to wait for it to come on in an emergency, and it's not going to come on too quickly just in your normal everyday stopping situation. Now for our manual override, you'll notice we do have the orange button here in the middle. This is basically going to come into play when you just want to apply the brakes on your trailer. So if you have a sway event or something like that, simply by hitting that button, you can see those brakes are going to be applied and will settle that right back out.Now the Echo is going to work in any of your working 7-poles. Basically, you just want to install it like you would your trailer plug. The thing I like about this with each manufacturer . Like on the Jeep here, for instance, the door opens from the side. On Chevys they kind of open up, so you have to have it in on the bottom. So regardless of which angle that we have to get this installed into the back of our truck, it's going to work equally as good. Now in our case, we're just going to open our 7-pole door. Keep in mind the tab that sticks up should always be towards the door. And we're going to slide that in just like a normal 7-pole plug. You'll notice we've got a LED light right here. It's flashing blue. That means that it is synced, so we already have our app open. It just doesn't recognize the trailer yet.That LED light is going to tell you exactly what's going on with your controller. The different lights mean different things, and the thing I like about that is that in your quick guide all of those are listed. So you don't have to go all the way back through your instructions or find it. Keep that quick guide with you. If you have any issues, it's going to let you know right there on the controller. Now we'll hook up our 7-pole from our trailer just like we would plugging it into the back of our vehicle. At that point, our brake controller is installed, and as long as you've got it paired to your smartphone it's ready for use.You'll notice our flashing green light once we're plugged in. That indicated to us that it is recognizing the trailer. It is getting power, but the app is not open yet. As soon as you open the app, the flashing green will turn to solid green. And to set up your brake controller, you'll need to download the current app. Once you initially get in there, it's going to have it get started right down here at the bottom. We're just a step beyond that, so we're going to hit the menu button up here. Once we select that, we're going to have sync devices. We've got right here. Allow it to look. Now one thing to keep in mind, of course, you do want the Bluetooth on your phone to be turned on. Here we see a found device. That's our Echo brake control. Would we like to pair with that Okay.At that point it asks us for our code. That's going to be a six-digit number. It's going to come in the package with your brake controller on your quick start guide, which is going to be here. You can see it's on the back. But if you happen to lose that card, it's also located underneath the lid on your brake controller. We've got our number entered, so we'll hit okay. As you can see now, it's going to show connected, pairing successful. We'll want to continue. You can see we've got the five different profiles to choose from. Now this can be different users. It can be different trailers. You've got several different ways you can set that up. Just get into our current there, and we'll see that we've got our output. We've got our sensitivity. That's our manual override right there, so you just hit that center button. That's going to take care of any of the sway events that you might have.And you see we've got our plus and our minus here. That's going to jump in increments of five. It's going to give us 19 different settings, so 19 different output settings. It's going to really allow you to adjust or fine tune your braking. Then to fine tune that further, we've got our sensitivity. Here you can see we have nine different levels, and that's going to change the quickness and aggressiveness in which our brakes get applied. So once we get into a heavier load situation or rough terrain, we want to increase that sensitivity. If we're driving on a nice flat level surface with an empty trailer, well, we want to bring that sensitivity down. We don't need that quickness and that aggressiveness. And also, we can adjust the theme. So we can go to a darker screen. It's going to be more beneficial driving at night. And if you choose, if you want to brighten it up a little bit you can for the day.Now from our operations screen, if we'll hit the menu, we can go to profile list. So we'll select that. Now from the controller profile screen, we can go to application profiles. You'll see here it says add profile. Basically, what we're able to do is name a profile specifically. So we'll go here. We already have one saved as Little Red. So we're going to do Black Tandem. It's one of the other trailers that we have here. Hit okay. We can go to our current profile. We'll see Black Tandem. Go back into it. Our settings are saved where we want them. Go back to our profile list, and we can select Little Red. Would you like to activate that Now a few things to keep in mind for increasing the user experience that you're going to have with the brake controller would be, one, you want to ensure that you update the app regularly. They're, of course, going to make changes and improvements to it, so you want to stay up to date.And the other thing we'd recommend is having your cellphone mounted on your dashboard. As you use the brake controller, the application is going to stay open, so it's readily available and easy to access. The situation with that would be if you've got it in your cup holder, if it falls off your seat on your floor, well, you're not within arms reach of it. So having a dashboard mount so you can keep your cellphone up here easily accessible is going to be the safest way to operate it. We do have a couple different dashboard cellphone holder mounts available. One that we'd recommend would be PC03. And it's also a good idea to have a power source plugged in. With the app staying on, of course, you can dim your phone screen down, kind of minimize the battery drain, but with the power source in there it's something you're not going to have to worry about.You'll notice the Grand Cherokee we've been working with today has an after market brake controller installed. That's just like the Silverado we we're working with earlier. However, that one is from the factory. The good news is with the Echo in line, it's going to stop the aftermarket or factory brake controller from sending it's signal through to the trailer. It takes all of the brake controller duties on until it's unhooked. At that point, your aftermarket or factory brake controllers are going to be right back working as they we're before. Now when comparing the Curt Echo to other brake controllers out there on the market, I think that the Tekonsha Prodigy RF is going to be the closest one. This is a brake controller system designed to mount and be permanently attached to your trailer.I think the Curt has some significant advantages in that this can be switched from trailer to trailer and vehicle to vehicle with zero issues or zero wiring really needed. Also, sometimes when pairing the Prodigy RF in a particular vehicle, it won't work. You'll have to use a second vehicle to actually get the system paired, and then get it in the vehicle that you want to use. This can lead to some headaches with certain vehicles and manufacturers. Another brake controller that it's going to be very comparable to is going to be the Prodigy P3. It's one of the best selling brake controllers that we have here at eTrailer, and people really tend to love it. With the P3, you're going to pick up a few additional axles as far as the capability goes. It's going to work for up to four axles. Very rarely are you going to see a triple or quad axle trailer, but some car haulers and campers do have them.So if your trailer has more than two axles, the P3 is going to be the way to go. We get slightly better diagnostics functions with the P3, but all in all it's going to take a lot more labor, it's going to take a lot more materials to get that brake controller installed in a lot of applications. Whereas, with the Curt Echo, simply plug it in. It has the diagnostic functions there that can help you in the event that we do have any issues. You can store the same amount of profiles, and overall the installation doesn't take any time at all. Now the only application we've really found so far where the Echo needs a little bit of assistance in working is on the Ford trucks. From '15 to '17, Ford kind of messed with the way that 12 volt power is supplied back to your plug on the back of your vehicle.What we recommend is just doing away with the factory 12 volt power going back and running your own 12 volt power through a circuit breaker from your battery. That alleviates that from the '15, '16, and '17 models. Now the good news, they've kind of revised that on the 2018. In that case, you just want to ensure that your total haul mode is activated. As long as that's activated, you're getting the power you need for this controller to work. And that's going to complete our look at the Curt Echo, part number C51180.

2018 Jeep Cherokee

I have not used it as of now. It is exactly what I wanted and works with My Jeep Cherokee that no one could tell me where to get brake signal to install a normal brake controller. This is a great option because I had the dealer install the a 7wire connection from Jeep and hitch but they know how to install a brake controller. Also there is nothing in the cab or holes drilled in the dash. Just all you need is a smart phone. Great concept and item to used on any vehicle even the new ones with all the things that controlled by the computer on vehicle and has to be reprogrammed by the dealer at a high cost. Will post later when I have used it and will let you know how it works. 607002

This is working great. Used going from Mississippi to Grand Canyon and back. Great for those vechile a that are hard to connect brake controller to and Dodge vechile said that dealers charge to program computer so permanent controller will work.

Just returned from a road trip using my new brake controller and everything worked as advertised. Connection with bluetooth was seamless and the app worked great, all connected with my travel trailer with no problems. Very pleased with the product. 602329

It’s been a year and my controller is working Great, now that I’m retired I’m using my trailer more and I’m very pleased with the ease of use and flexibility this brake controller provides.

Another great product from Curt and eTrailer! I was looking for a trailer brake setup that I could use on different trailers. The Curt product and eTrailer video helped me select this product. It's easy to set up and use, and works great with my tandem car hauler trailer! 704265

This unit draws power from my travel trailer so will only work when hooked up to it. 705715

2019 Dodge Durango

This is a great brake controller. The only issue I had was that the instructions state that you need your car engine running and it would connect via Bluetooth to the controller.. However, in my case, and it just may be my car model and make, the controller only connected "after" the trailer was connected to the plug.. But no biggie, it worked great and easy to set up... 717296

- C51180

Wasn’t a great fit for my application because my 7-pin socket on the car angles down at 45 degrees and after the brake controller is installed and the trailer pigtail plugged in the cable hangs down pretty far. It hangs lower than the safety chains. It could be an issue. Otherwise, the controller paired right up and seems to work fine. 691278

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. 588470

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

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. 656462

Easy to set up and use, even for me who had never used trailer brakes before. Hauled my 10k trailer from Ohio to Idaho and it worked like a champ through the mountains and plains alike. I'm quite happy with it, had no connection issues, could hook up to my headset at the same time even though I have a pretty cheap phone. The app design leaves a bit to be desired, but is simple enough. 655051

Toyota Echo

I was pleasantly amazed at how simple the Curt Echo trailer brake controller was to install and use with my camper. Instead of spending a minimum of 8 hours and finding all the necessary accessories for a typical hard wired controller, I just plugged it , synched it and was done. It worked flawlessly on the first trip and I could not have been more pleased. Also, the vehicle I plugged into was not factory wired for towing lights but the Echo still worked without a problem. 655881

- C51180

This product has worked very well. I don't have a lot of experience with other brake controllers, but this little guy makes it very easy. There is NO wire installation. I just plug it in to my 7-pin connector then plug my trailer in to this. I connect my phone to it, and we're good to go. It very easy to adjust the settings when I need to. My phone can still connect to the car bluetooth at the same time. I have had nothing but a positive experience with this product. 668430

- C51180

Be cautious of this unit. It works but has a lag in braking apply and release. Also be aware that the blue ring may not always show your braking force, which makes you question if it is even working. For a blue tooth unit, with no wiring, it works as expected. 2018 f150 669016

2018 Chevrolet Silverado 1500

So far this works. It works and the app does not need to be on as some seem to think. I set up my phone so the app stays active in case I need to use the manual stop. The set up easy and the app is easy to use. Tweeting and adjusting was a breeze as I did it with only 4-5 slow and fast stops. I plan to put 1500 miles on it over the next 3 weeks so if things change I will update. 658190

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. 647505

2018 Acura MDX

I purchased a 2018 Winnebago View(2017 Mercedes Sprinter chassis) and while it came with a hitch and 7 pin connector, it did not have a brake controller. The camping store tried to install a traditional controller but was unable to. While etrailer has a very nice video on installing a controller on the newer chassis, actually finding a shop to do the installation was difficult. Low and behold, when getting ready to order the parts from etrailer, I came across the Curt controller. I ordered one, received it in three days, it took about 15 minutes to install(from opening the package, downloading the app, pairing to my phone and adjusting the controller). Worked perfectly on a 500 mile trip that weekend. The even better part about the Curt controller is that it should work perfectly on our Acura MDX which likewise came with a hitch and 7 pin connector but no controller. 5 stars for convenience and usage. 597576

2014 Audi Q5

After a lot of research I purchased the Curt Echo Trailer Brake. I was looking for a trailer brake controller with a non-permanent installation, one that I could take out of the vehicle when I wasn’t using it. I was a little anxious because I have a European SUV and have read all the stories of the complications that can come with wireless/Bluetooth connections to the controller. After looking around for the best price I found that etrailer.com was competitive, and ultimately I went with them because of their reputation for service. I was not disappointed. My parts arrived sooner than expected and installation was a breeze. The Echo installed without any issues in a matter of minutes and works perfectly with my Audi Q5. And, no permanent fixture screwed into the dash of my SUV. Thanks etrailer. 605706

I just tried this out today I was amazed as to how easy it was to download the app and to set it up I am glad i decided to go this route as I have 2 vehicles that I want to use to tow my trailer I wound up staying with the default settings as it worked best that way 612554

2008 Cadillac Escalade

The part is not turning on when plugged in, I need to do some diagnosis on my end to see if my plug on the truck has power. 581419

I dont know if you have ever had the towing package on the Escalade activated before but there are two studs in front of the fuse box under the hood. There will be two wires you will have to connect to those studs before the 7-way plug gets power. I have attached a video of a brake controller installation on a 2009 Cadillac Escalade. You can ignore the installation of the brake controller until the video gets to the 7 minute mark of the video.

  • Easy to Install Brake Controller Recommendation for 2020 Jeep Grand Cherokee
    I have the perfect brake controller solution for you with the Curt Echo Mobile brake controller part # C51180. This controller requires zero wiring and also does not attach to the dash so you wouldn't have to modify your vehicle interior in any way either. This basically just plugs into an active 7-way trailer connector like you have at the rear of your 2020 Jeep Grand Cherokee and once it's synced to a smart phone you are ready to tow. I attached a review video for this controller...

  • 2020 Jeep Gladiator Trailer Brake Controller With Wiring Harness
    That's a good question, and what happened was that when the 2020 Jeep Gladiator first came out, there was a brake controller harness manufactured by Curt that was thought to work with the Gladiator, but it turned out not to be the case. The leading manufacturer, Tekonsha, took their time and made a brake controller harness that has proven to work for a 2020 Jeep Gladiator with the factory tow package, the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Jeep # 3073-P. These...

  • Will Curt Echo Brake Controller Continue to Operate with Phone Turned Off
    After the Curt Echo Wireless Brake Controller # C51180 is installed and paired to your phone it will continue to function as a proportional brake controller whether or not your phone is on. If your phone happens to die mid-trip, the brake controller will continue to operate without issue with the most recent settings applied. The only thing you will lose in this scenario is the manual override function, which is operated by touching the big red dot on the phone screen. This may be needed...

  • What is Required to Use Curt Echo Trailer Brake Controller
    To use the Curt Echo Wireless Trailer Brake Controller # C51180 your vehicle only needs 12 volt, ground, and turn signals connected to its 7-way socket. What this means is you do not need the brake signal from the 7-way. 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. Apart from that the only other thing required is that your...

  • Is Reverse Light Circuit Needed When Using the Curt Echo Bluetooth Brake Controller
    If you purchased a 4-Way/7-Way Hopkins adapter like part # 37185 so that you can use the Curt Echo Mobile Trailer Brake Controller # C51180 then you are correct about only needing to connect the 12V power wire for the brake controller (in addition to connecting the typical trailer light circuits and ground). The reverse light wiring is optional and is really only needed if your trailer has a separate circuit for the reverse lights. We actually created the kit # ETBC7L for people who...

  • Installing Curt Echo Brake Controller in 2019 Ford F-150 without Factory 7-Way
    So each 2019 Ford F-150 is going to have either a 7-way or 4-way connector; the 7-way would be obvious and you'd know if you had that, which means you are going to have the 4-way. It will be there, possibly hidden, so if you cannot find it you are going to want to check behind the rear axle on the driver side frame rail, and you should see the plug there. Once you find it you will be able to use the Curt Echo Brake Controller # C51180 on your F-150 by installing the 7-Way RV Upgrade...

  • 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. You would need to test the wires at the brake pedal for the wire that only shows power when the brakes are applied using a circuit tester like part # PTW2992. That is the wire that you would attach the red wire from coming from the brake controller. I have attached a diagram that shows how to wire the 7-way plug and brake controller into...

    I have a super easy brake controller solution for your 2017 Ford Explorer with the Curt Echo brake controller part # C51180 which plugs into an active 7-way and once synced to a smartphone is ready to tow. For an easy to install 7-way kit all you need then is the part # C56306 which plugs into the square trailer wiring connector at the rear of your vehicle. I attached an install video for this that shows it installed on a 2017 Explorer just like yours. Other installs will require...

  • Wiring Needed to Use Curt Echo Brake Controller on a 2006 BMW X5 with 4-Way Flat Connector
    You are most of the way there! The Curt Echo Mobile Trailer Brake Controller # C51180 that you purchased for your 2006 BMW X5 just needs the basic trailer lighting functions and 12V power to be fully operational. A 4-Way Flat connector like the popular Tekonsha ZCI # 119250KIT provides the basic trailer lighting functions so once that is installed you simply need to install the 7-Way RV Upgrade Kit # ETBC7L. This includes the 4-Way to 4-Way/7-Way adapter as well as wiring for you...

  • 4-Way to 7-Way Adapter Recommendation for Installing Curt Echo Brake Controller
    If your plan was to install a brake controller you'd have to also run the black wire of the 7-Way Adapter part # 30717 to the to the positive post of your vehicle battery as well as the ground you mentioned. The Curt Echo part # C51180 that you referenced needs the black wire to power it and then uses the other signals from the 4-way adapter to tell when the vehicle brakes are on. For a different adapter that comes the extra wire and breaker to activate the needed circuit for the Curt...

  • Will Curt Echo Wireless Trailer Brake Controller Work on 2019 Toyota Highlander
    Trailer brake controllers are universal parts and will fit any vehicle, including a 2019 Toyota Highlander. As for your first question, the issue with installing some brake controllers on some Toyota's is disconnecting the brake light switch can set off a code in the computer that limits the vehicle's motion. That is not a concern with the Echo because it will mount directly in your Highlander's 7-way. The Curt Echo Brake Controller # C51180 does not need the brake wire, it only needs...

  • Curt Echo vs Tekonsha Prodigy P2 Brake Controller for 2019 Kia Sorento
    The Curt Echo # C51180 and the Tekonsha Prodigy P2 # 90885 that you're deciding between are both excellent proportional brake controllers but as you mentioned, their installation, operation, and physical design are all quite a bit different. Between the two options I recommend going with the Curt Echo # C51180 for your application because it will offer an easier installation process and its convenient operation is simply better fitted for occasional towing like you plan on doing.

  • Brake Controller Recommendation for 2020 Kia Telluride with 4-Way
    So the easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180 which is what I recommend for your 2020 Kia Telluride. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount of deceleration your tow vehicle is applying and applies the trailer brakes in a relative way. To convert the 4-way to a 7-way so that you can install the...

  • 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...

    We have everything you'll need to install and wire up a brake controller and 7-way in your 2019 Subaru Outback Wagon. The easiest to install brake controller that also happens to be one of the best performing models is the Curt Echo part # C51180. This actually just plugs into a 7-way that has taillight functions and 12 volt accessory power ran to it and once you sync it to your phone you'd be set. The first thing you'll need wiring-wise is a 4-way (if you don't have one already),...

  • Recommended Trailer Brake Controller and Wiring for 2019 Honda Odyssey
    Starting with the brake controller itself I highly recommend the Curt Echo # C51180 for your 2019 Honda Odyssey. This is a really unique controller that allows for an extremely simple installation that involves simply plugging it into a 7-Way connector on the vehicle and pairing to your smartphone via Bluetooth after downloading the free app. It will provide automatic proportional braking that will activate the brakes on the trailer at the same time and with the same intensity that...

  • Wiring for Curt Echo Mobile Wireless Brake Controller and Adding Electric Brakes to a Trailer

The 7-way connector that you mention part # A10-7084VP pugs into the 4-way connector you purchased part # C56217. The white wire from the 7-way plug needs to be grounded to a clean bare metal surface on the vehicle's frame. You are correct, the black wire from the 7-way connector needs to be extended from the plug into the engine cavity and to a 40 amp circuit part # 9510...

  • Installing Trailer Brake Controller on 2018 Ford Transit T250 with Factory 7-Way
    There is not a factory brake controller plug-in port on your 2018 Ford Transit T250 so in order to install your existing Tekonsha Primus Brake Controller you will need to hardwire it in using the Wiring Kit # 5506. This kit will provide you with the power and ground wires for the brake controller along with the needed circuit breakers. The red wire from the brake controller will then need to be spliced to the cold side of the brake light switch on the Transit. This is the wire that only...

  • Parts Needed to Install Curt Echo Mobile Brake Controller on 2015 Ford F-150 with 4-Way
    The Curt Echo part # C51180 needs a 7-way trailer connector with the 12 volt accessory circuit active so for your 2015 Ford F-150 that has a factory 4-way you'd just need the adapter part # 37185 and to then connect the black wire of the adapter to the trailer wiring bundle present at the rear of the truck. I attached a link to a picture on this page that shows where to find the orange wire on your truck's frame rail as well as a link to a help article that covers this also.

  • Easy to Install Brake Controller Recommendation for 2019 Hyundai Santa Fe
    I have a really great option for a brake controller for your 2019 Hyundai Santa Fe. I recommend the Curt Echo brake controller part # C51180 as it's very easy to install and use, but also what's great and unique about this controller is that it's self-contained at the trailer connector. You don't have to mount anything to your dash at all and you also don't have to wire anything up for it specifically either. Basically you just need to start with a 4-way if you don't have one with part...

  • Recommended Trailer Brake Controller for 2016 Audi Q5 TDI
    If they installed the OEM tow package wiring in your 2016 Qudi Q5 TDI, then there should be the connection under your dash for the wiring harness to be a simple plug and play. The Curt Custom Wiring Adapter for Trailer Brake Controllers # C51522 will have the plug for the factory harness and then you can use the Curt Spectrum # C51170. This proportional controller will have a much cleaner look on your dash so it is what I recommend if you have the plug in harness. If you don't have...

  • Parts Needed to Install Curt Echo Brake Controller # C51180 in 2018 Toyota Highlander
    As long as you have a functional 7-way at the rear of your 2018 Toyota Highlander the Curt Echo brake controller part # C51180 will fit just fine and work well. If you need a 7-way you'd need to first start with a 4-way (if you don't have one of those either). For that you'd want the Curt part # C56217 which is a confirmed fit and then to convert to a 7-way you'd want the part # 37185. From there you'd just need to connect the black wire of the adapter to the positive post of the battery...

The kit includes an adapter to convert your 4 pole into a 7-way and the hardware, wire and circuit breaker needed to connect...

At this time (April 2020) there isn't a harness from Curt that fits your Gladiator.
