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.

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 brake controller and then plug the other end into the built-in port behind your vehicle's dash.
Features:
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 connector underneath your vehicle's dashboard, located to the right of your steering wheel.
No hardwiring is required to install this adapter. After you plug it into your vehicle's connector, 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.

Adapter was the right part for the brake controller.
This is an excellent adapter for trailer break
worked as promised - made it easier to pull a4 place snowmobile trialer
Easy install. Perfect fit
The product came very fast and it was super easy to install. It's working better than I thought, I'm very happy with www.etrailer.com and there products. Definitely worth every penny and everything top quality. Thanks!!!!
Took about 10 minutes to install. Have not made all the adjustments yet, but is easy to understand.
Great controller! Easy to adjust even on the fly. I had the controller adjusted a little aggressive and as I was trying to get out of Buffalo to go south for the winter we ran into some snow accumulation and was able to quickly dial back the controller to avoid locking up on thick snow covered roads. Literally a potential disaster! Very happy with the controller
Works like it should
Tested . Work fine and advertised
Everything was plug and play. Installing it was straight forward after viewing instructions.
Fit and worked
excellent service and delivery.
This harness made for a clean, splice-free install. I used this with a Jeep Gladiator which requires swapping the black and blue wires in the gray connector. The Gladiator is such a new truck, I could not find a good cross reference for the exact harness for a Curt Spectrum controller. I’m sure they have one by now or will very soon. I didn’t bother calling etrailer, I knew I could make this harness work. The wire swap took less than a minute, once you see the pin latches. Well worth the money to have a solid and clean install.

Curt does offer a wiring harness for the 2020 Jeep Gladiator and it is available as part # C51459. This harness has the correct plug configuration for the Gladiator and does not require swapping the black and blue wires.

It's very well made and would be simple to use, except two of the wires were switched. We used this with a 2018 Jeep Wrangler JL, but apparently they are switched on newer Dodge trucks too. Unfortunately, the effect was that the trailer brakes stayed permanently on.
I believe it was the brake signal and the 12V wires that were switched. Unfortunately, I don't remember for sure, but etrailer support knew exactly the issue and told me which two they were.
There are two ways to fix this. The ugly way is to cut and splice the wires to their correct place. That's the way most people recommend, but there is actually an even easier way with no cutting: remove the orange insert from the end the plugs into your car's wiring (I believe there were tabs on the side that I had to press to do so). Now, you will be able to remove the wires/contacts from the connector, so simply switch the two that need to be switched. Click the orange piece back into place. Voila, it's fixed, no cutting required.
Anyway, apart from that wire switching issue, it's a nice product.
Worked great on my Ram, fast shipping.
I just installed my Curt TriFlex Trailer Brake Controller C51140 in my new 2019 Ram 1500 Laramie 4x4 Crew Cab. Thanks to the Curt Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In # C51458, it only took 4-5 minutes. Hardest part was finding the factory connector under the dash to plug into. etrailer has this wiring adapter listed as "Not confirmed to work" for the 2019 Ram 1500 but after my test drive I'm very satisfied. Worked just as I expected. I'll update this review after I have more time behind the wheel towing.
I recently purchased a 2018 Dodge Ram 1500 and traded in my 2014 Dodge Ram. I had removed my Curt brake controller and was to install it in the new Ram. Unfortunately, the connections were not the same, and I needed an adaptor. I called etrailer and was extremely happy with the service. Tammy looked up my truck and controller and matched the adaptor. The process took less than 3 minutes. I received the adaptor in just days. Thank you Tammy for making this easy.
Very happy with controler and bracket. Easy to install took me only minutes.
Very happy
Like its compact size and simple operat ion.
Very helpful, knowledgeable and friendl y!
Came in exactly as I expected, looked up under the dash and found the wire, should be a ten minute install. Sure makes it easy when etrailer has your vehicle specific cable for install. Will have to add more when I get to use it under tow with my RV trailer.

The cable install fit perfect and my system works great, the install was less than five minutes. Thanks etrailer!
Thank you Paula, great help. Enjoy the rest of the summer.
I needed this adapter to connect the brake controller to my specific vehicle. Etrailer had it available when I bought the controller from them , so I ordered it. Easy connection, works great.
Have a 2015 Dodge Ram 1500. After searching countless hours to find a "plug-n-play" trailer brake, I found etrailer. They sent me my trailer brake AND a pre-wired harness/adaptor that plugged right in to my existing harness under the dash. Awesome customer service!
