Curt Accessories and Parts - C51458

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:

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connectors plug into the built-in port underneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Curt
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses
  • 2' Long, 12-gauge wires have protective covering to deter damage
  • Limited 1-year warranty


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.

Video Transcript for Curt Brake Controller C51458 Review

Today, we're going to be taking a look at the Curt Custom Wiring Adaptor for Trailer Brake Controllers. The Plug-In Wiring Adaptor is going to allow for a quick, simple installation of your electric trailer brake controller, does not require any cutting or splicing, very simple installation. You're going to have specific connectors or custom connectors located on each end of the wiring. One end is going to plug into the the built-in port beneath the dash of your vehicle, the other end is going to plug into the back of your electric brake controller. This is compatible with time-delayed and proportional brake controllers from Curt. Just keep in mind that the brake controller must have the built-in plug or built-in port for the adaptor to connect to. This will not work on controllers with pigtail wiring harnesses.

The unit is going to measure about 2 feet long and the wires are protected with the wire loom to deter damage and it's going to keep the wires bundled together so they'll not hang lose around your feet or around your pedals. Because there are no wires to connect, it has these specific or custom ports on it, because there's no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time, which makes it very easy to transfer it to another vehicle or securely store it away while it's not being used. That's going to do it for today's look at the Curt Custom Wiring Adaptor for trailer brake controllers.

Best price out there. Would be nice if Mfg. offered in shorter length. No issue though, plenty of room under dash to coil up excess. 592953

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. 575964

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. 505309

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. 484266

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! 382925

  • Wiring Adapters Needed for 2012 and 2015 Ram 1500 Brake Controller
  • The 2012 Ram 1500 and 2015 Ram 1500 do not use the same brake controller harnesses. If you are using a Tekonsha, brake controller, your 2012 Ram 1500 will be using Wiring Adapter # 3021-P and your 2015 Ram 1500 will need Wiring Adapter # 3024-P. If you are using a Curt brake controller, your 2012 Ram 1500 will be using wiring adapter # C51438 and your 2015 Ram 1500 will need # C51458. If you are using a Hopkins brake controller your 2012 Ram 1500 will need wiring adapter # HM53015 and...

  • Is Pilot Brake Controller Compatible With 2018 Ram 1500
  • I reached out to the manufacturer of the Pilot 2-6 Brake Electronic Brake Controller # 80550. They just advised me that the Pilot # 80550 will not work on a 2018 Ram. The reason why is because the brake light signal circuit only outputs 4 to 6 volts (the Ram requires a controller that can output at least 12 volts) which isn't enough for the brake controller to function properly. As an alternative, the Curt Venturer Trailer Brake Controller # C51110 will work for the 2018 Ram 1500....

  • Wiring Adapter to Install Curt Venturer Electric Brake Controller in 2015 Ram 1500
  • To install the Curt Venturer Brake Controller # C51110 in your 2015 Ram 1500 the wiring adapter you need is # C51458. With that being said you might consider a proportional brake controller like the Tekonsha Voyager # 39510. A proportional controller senses the rate at which your truck is stopping and applies the trailer's brakes accordingly. Where a time delayed sends the same, preset, amount of braking power to the trailer every time. So a proportional will have smoother braking...

  • Brake Controller Install Harness Recommendation for 2018 Jeep Wrangler
  • Yes, I confirmed with Curt that the trailer wiring install harness part # C51458 that you referenced is a confirmed fit for your 2018 Jeep Wrangler and will make installing a brake controller easy. It will plug right into the port under the dash of your vehicle to make installing the brake controller easy.

  • Curt Brake Controller Install Harness for 2017 Ram 2500
  • For 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.

  • Recommended Trailer Hitch for Towing a Car Hauler with a 2019 Ram 1500
  • The hitch to fit your 2019 Ram 1500 is the Draw-Tite # 41913. It's custom designed to fit your truck and has plenty of capacity to tow a car on a trailer. You also need a ball mount, hitch ball, and pin and clip. I've linked our selections of each but you also may want to look at an adjustable ball mount. This way if you tow a different trailer sometime it'll be more likely to work for you. A good choice that has all three ball options is the Buyer's Products # 3371802225. You also...

  • Brake Controller Won't Light Brake Lights When Using Manual Override Slider On 2016 Ram 1500
  • The 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. To adapt your...

  • Needing the Brake Controller Wiring Harness for the Curt Venture Controller on a 2017 Ram 1500
  • On your 2017 Ram 1500, the Curt Venture Brake Controller, # C51110, will need to use # C51458 brake control harness to install on this truck. The harness will pug in to the brake controller's harness and the other end will connect to your Ram's wiring. The wiring harness # C51453 that you referenced was used up to the 2014 Ram 1500 and is not needed on the 2015-2017 model Rams.

  • Which Curt Brake Controller Harness Fits a 2015 Ram
  • Part of the problem is the harness you are using is the incorrect one. You would need the part # C51458 for your 2015 Ram 1500 and not the # C51453. The correct harness for your does not have the extra wire that you are mentioning since your truck does not require it.

  • Brake Controller Plug-n-Play Adapter for a 2016 Ram 1500
  • The only real difference on the brake controller plug-n-play adapters is the end that connects the to brake controller itself. The end that plugs into your 2016 Ram 1500 is the same on all of the adapters. Since the Tekonsha and Curt brake controllers are our 2 most popular brands, here is a wiring adapter for both brands. If you were looking to use a Tekonsha Brake Controller, like the Primus IO # TK90160, Prodigy P3 # 90195, Prodigy P2 # 90885, or the Voyager # 39510, then you will...
