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.

Just what I needed
Seems to consistently work. No issues.
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
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!!!!
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.
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!
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.
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.
Adapter was the right part for the brake controller.
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.
Great little plug and play. Great customer service!
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!
Very happy with controler and bracket. Easy to install took me only minutes.
Just got my trailer brake installed, took less than 30 minutes. The wiring harness that was made for my truck pugged in with no problem. I have already tried it and it works great. Shipping notifications were updated every day so I knew exactly when to expect it. Their pricing was competitive with eBay and Amazon. I cannot say enough good things about this company and their service, I highly recommend them.
Works perfect on my 2026 RAM 1500 pick up. One big advantage of ordering from etrailer is the information they have on their website that shows where the location of components and how to complete the installation. Highly recommended:
Glad the website recommended this. It was very easy to install, just plug it in to the existing wire connector under the dash by the accelerator pedal and the other end in the controller.
Great instructions easy to find factory plug-in and plug this adapter for my brake controller.
I could not find this quick connector anywhere in town so I did an internet search and etrailer had the best price. This connector worked perfectly and was very easy to install.
Controller got here quickly, Not hard to install on my RAM once I found the factory plug for after market brake controller.
Pulled my travel trailer this past weekend and the Curt control worked well.
This is an excellent adapter for trailer break
Great company with excellent customer service. Item shipped and arrived quickly! Made hooking up my brake controller a breeze. Very satisfied with etrailer!
Everything was plug and play. Installing it was straight forward after viewing instructions.
Easy to install
worked as promised - made it easier to pull a4 place snowmobile trialer

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.
