Installation of Curt Brake Controller Adapter
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.

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.by: Brian04/21/2021
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
by: Antonio05/08/2016
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!!!!

Hard to beat plug & play.
by: Dominick P.09/25/2019
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.

Easy to order and reasonable fast.

Very happy with controler and bracket. Easy to install took me only minutes.
by: Markus08/18/2019
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.
Comments
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.

2019 Dodge Ram Pickup
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.

2018 Dodge Ram Pickup
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.
by: Robert03/12/2018
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.
Comments
The cable install fit perfect and my system works great, the install was less than five minutes. Thanks etrailer!

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!
by: Larry C 09/07/2019
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.
by: Tim01/28/2019
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.

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:
by: Michael J. 06/22/2017
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.

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.

view full answer... - Is Curt TriFlex Trailer Brake Controller Compatible with a 2019 Ram 1500 New Body StyleThe Curt TriFlex Trailer Brake Controller # C51140 is a confirmed fit for your 2019 Ram 1500 New Body style. All you need is the Wiring Adapter # C51458 for a plug-in installation! I have attached the installation instructions for you to check out. I'm not sure why someone would say a traditional-style brake controller like this won't work with a vehicle (much less a pickup truck) because these types of brake controllers are very universal and usually if there isn't an adapter for it...
view full answer... - Why Is Stoplight Circuit Difficult to Find on 2017 Ram 1500 For Installing Brake ControllerYour generation of Ram truck uses a powernet style of wiring at the brake switch wiring which means the voltage will actually read lower than what a 12 volt circuit tester is going to show. Also if you are trying to hardwire a controller you are going to have issues as we've found that if you don't use a harness designed specifically for your truck's wiring setup you may damage the vehicle. So to install the Curt Discovery part # C51120 you have to use the vehicle specific install harness...
view full answer... - Can Curt Spectrum Install a 2019 Ram 1500Yes, the Curt Spectrum # C51170 will fit and work great installed in your 2019 Ram 1500. There's not reason it wouldn't be compatible. The install harness needed would be the part # C51458 but it sounds like you have that already.
view full answer... - How To Use Curt TriFlex Trailer Brake Controller On a 2018 Ram 1500The Curt TriFlex Trailer Brake Controller part # C51140 is an excellent option for a 2018 Ram 1500. That said, you'd also need the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51458 for plug-in-play installation. In regards to the factory brake controller, these aftermarket options are much more reliable and offer better performance. There is really no comparison and many swap out the factory brake controller for an aftermarket brake controller.

The TriFlex is a solid proportional controller with 9 sensitivity settings to fine-tune your braking and a diagnostic system that will constantly keep you up to date on any potential issues....
view full answer... - Curt Brake Controller Install Harness for 2017 Ram 2500For your 2017 Ram 2500 the correct Curt brake controller install harness is the # C51458 which will work great with most of the Curt controllers but not the Discovery as this controller does not like the lower voltage that your truck puts out for the brake signal. You would have to go with a new controller like the Venturer part # C51110.
view full answer... - Brake Controller Wont Light Brake Lights When Using Manual Override Slider On 2016 Ram 1500The wire colors under the dash are not designed to match on any vehicle, they match function but not color and the Curt Brake Controller Adapter # C51458 is the correct harness for your 2016 RAM. I reached out to my friend at Curt and he confirmed that when you use the manual override slide on your Curt Venturer Trailer Brake Controller, # C51110, it is designed not to send power to your vehicle brake lights. It sends signal to your trailer brakes, but not to the lights.
view full answer... - Where Does a Curt Venturer Brake Controller Plug In on a 2016 Ram 1500In order to install the Curt Venturer brake controller # C51110 on your 2016 Ram 1500 you will need wiring harness # C51458.

I included a picture showing the location. the picture is from the instructions for # C51458 which I have also linked for you.
