An easy-to-read digital number display, 10 power levels, and a pinch-trigger manual override make this time-delayed brake controller easy to use. Installation is simple with no mounting restrictions. Activates brakes with a preset intensity.
Features:
Specs:
Gain control lets you set the maximum amount of power that will be applied to your trailer's brakes, adjusting in increments of 0.5. 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. You want to go as high as you can without the trailer brakes locking up. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes. To get more power to your brakes, press the upper orange rocker switch. To decrease the gain, press the lower switch. When you make your adjustment, the gain setting will show on the LED screen for 10 seconds as a series of bars and then go into sleep mode.
Once you have the gain set, you can fine-tune your braking by adjusting the load control on a scale of 1 to 9. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. Load control can get the braking power to your trailer faster and with more intensity so that it doesn't push your tow vehicle forward. If your vehicle takes too long to come to a stop, increase the setting by pressing the upper black rocker switch. If it stops too abruptly, decrease the setting by pressing the lower switch. You can alter the setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.
The Discovery comes with a easy-to-reach, pinch-trigger manual override, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push in the trigger. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.
The LED display on the Discovery is large and easy to read at a glance. It will show you what setting the brake controller is on as well as give you information for troubleshooting. You can adjust the screen brightness or trigger night mode so it won't glare obnoxiously on your dash. Press the control button to cycle through the different modes.
Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. Your mounting options are limitless, so long as you can still easily access the controller and the manual override. The included bracket is designed to mount the brake controller flush to the dash so it takes up almost no space at all.
If your vehicle already has a plug-in brake controller wiring harness, just connect the unit to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.
Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:
20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications
30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications
See also etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.
The Curt Discovery comes equipped with time-delayed braking. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Discovery. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (gain) and rate of application (load) can be adjusted to suit your preference, the road conditions, the type of trailer, and the weight of your load. To determine which levels are best for your application, test your towing setup and choose what feels right.
Install your Curt electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your controller and then plug the other end into the built-in port beneath your vehicle's dash.
Features:
Note: The factory brake controller plug on certain Nissan Titan XE models has a pin configuration that does not match up with this adapter plug. To install this adapter in those vehicles, hardwiring is required.
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 in most vehicles. 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.

The Curt Echo is now on my Nissan Armada and works perfectly. It was an easy hookup with the supplied harness and does its job.
I've had the brake controller in use for over a year in my 2012 Nissan Frontier. The install was easy and took about an hour. My truck is a 2WD model so I mounted the controller in the plug that is used to select between 2WD and 4WD on vehicles equipped with 4WD. So the install look like factory.
Simple connection. FYI: On the 22-24 Nissan Frontier the plug-in is left of your left knee, above the kick panel. It is the larger of the 2 white connectors. No need to take kick panel off.
This custom wiring adapter made hooking up my Curt controller very easy to my factory wired nissan frontier.
Took about 10 minutes to install. Have not made all the adjustments yet, but is easy to understand.
Plugs right in without effort. Stiff enough that it loops behind dash and is well hidden
it worked as it was designed to
Tested . Work fine and advertised
For the most part I have been very happy with the merchandise that I have ordered from etrailer. But right now, I think that the people pulling the orders have to slow down a little and look closer at the details. I had ordered a C51382 cable but was sent a C51362 cable. They are not inter-changeable. They are shipping a new cable today (Tue.) I am supposed to get it by Thursday, depending on what time it gets here I may be able to get it done Thursday night and then calibrate the brake controller. Otherwise I am supposed to be on the road Friday but first I will have to take care of this and calibrating the brake controller on top of everything else.

I will have our customer service team reach out to you.
So much easier than cutting wires and crimping butt splices. Plus it make un-installation easier and doesn't void the warranty for the brake controller. the time saved was worth the money for me.

One year later and unlike my guitar hero drum kit the insulation on the wires has not cracked and fallen off yet. Plus its nice to be able to unplug the unit from the car.
excellent service and delivery.
I ordered this wiring harness because it said it would work with my 2004 Nissan
Titan. It does not. The plug on one end of the harness matches none of the plugs on the truck wiring.

Thanks for pointing this out, Russell. The factory brake controller plug on some vehicles primarily XE models do not have the 4 pins to match up with the adapter plug. The factory plug will need to be hardwired onto the brake controller adapter that was purchased.
Your company is awesome! I can’t write about the brake controller because my mechanic is putting it on today and it is the one he recommended. What I can write about is the customer service. You made ordering simple and the follow-up is fantastic. Delivery was quick and there were no delays. I will use your company again — and again. Thank you…
Like its compact size and simple operat ion.
Worked great. Exactly what I needed to hook up my brake controller on my 2018 Nissan Armada
Very helpful, knowledgeable and friendl y!
The trailer light kit I got was very easy to install with the helpful video and instruction etrailer has. etrailer made it very easy to select the correct trailer accessories for my Frontier. They were helpful when I called and the website is very easy to use! I have made other purchases through etrailer because it is easy to use and they have what I needed all in one place. Thanks!
Great product!!! Installed in a matter of minutes. Determining where to attach the control took longer than the install. Pulled the trailer on a trip on roads with several steep inclines and applied the trailer brakes sparingly on the decent. Was able to adjust with the proper brake applications needed. Worked great. Made me feel confident that I could control the trailer on any road way. I very much recommend this trailer brake control for two axle trailers.
Item arrived 3 days early and was exactly what I needed. Customer support was excellent. I highly recommend and would gladly use etrailer again.
Ordered gooseneck hitch, wiring harness and break controller for my truck. Perfect fit , easy connections best purchase ever made on internet. Very good price and great customer service! ??
This product is easy to install with the correct harnesses. It is relatively basic, but it handled our application quite nicely. I was a complete novice when I started this project and had to learn as I went, but this is a nice brake controller.
Truly plug and go, except at the back of the truck when the trailer plug harness plugged in, the brake wire and power wire were crossed. Research explained that Nissan Frontier's are known for the unconventional switch with aftermarket wiring. I simply cut, switched, soldered. All good now.
etrailers out did my expectations. I ordered a trailer brake controller and pigtail one day, and they were at my doorstep the very next day. Boy, talk about fast. My rig works great , easy as pie setup, good price ( and I did look around), no problems at all. You guys are great. I will be buying from etrailer.com again for any of my trailer and accessories. Great job guys and girls.
recently purchased a Curt Venturer Brake controller with wiring harness for my 2014 Nissan Frontier. installation was as easy as shown in the video. after hooking up camper, initial brake setup and test drive was 10 minutes! everything should be this easy!
