  • Tekonsha
  • Vehicle Specific

Install your electric 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 harness beneath your vehicle's dash.


  • Wiring adapter eases installation of your electric brake controller
  • Custom connector end plugs into the built-in port beneath the dash of your vehicle
  • Other end plugs into the back of your electric brake controller
    • Compatible with proportional brake controllers and certain time-delay brake controllers from Tekonsha
  • 1-Year limited warranty

Note: To illuminate your vehicle and trailer brake lights when you activate the manual override on your brake controller, use in conjunction with the Tekonsha brake controller converter with 7-way adapter (30235-P - sold separately). Required for use in the state of California.

Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.

This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2019 Dodge Ram Pickup

This wiring adapter make it so easy to hook up my brake controller. I took my old brake controller (Primus IQ) out of my old truck which had to be hard wired and installed it on my 2019 Ram 1500. It was so easy, just plug and go, worth every penny.

Smooth breaking, works great was such an easy install

Wiring adapter worked perfect

2016 Toyota Prius

This made the install very easy. I was able to toss the wiring parts that came with the brake controller and just plug this in on both ends and go on with my day. Picking where I wanted to mount the controller took longer than installing it


Installed in my 2020 Gladiator and used the 3024P adapter(you must switch the black and blue wires!) it works perfect. Yes i cut a hole in my new truck but it is out of the way and you can easily access it.
Shipping was timely product was excellent.

Still working great!

2017 Dodge Ram Pickup

I purchased a new 2017 Ram 1500 and was looking for a break controller. My son recommended the Tekonsha Prodigy 2 . I found it on at a better than expected price and ordered the controller and the wiring harness. I received the item in four days. It was a breeze to install. Truly plug -and-play ! Set up was a snap and I like not having to level the device every time , as with my previous controller !
I am very satisfied with my purchase and with !

2019 Dodge Ram Pickup

Easy install with matching wire harness for your vehicle. This controller with proportional braking is a lot of tech for the money and can be programmed easily in a few minutes for your trailer applications. I installed this on my 2019 Ram 1500 Laramie in 1/2 hour, most of that time was figuring out where I wanted to mount the unit. Works flawlessly, and can be be removed from the bracket in a minute and stored in the glove box (if you use the plug in wire harness to match your vehicle. This is a much better controller and several hundred dollars less than a dealer installed controller.

This wiring harness was a perfect plug and play for my 2019 Ram. Worked flawlessly, minutes to install.
Richard N - 07/18/2021


Just wanted to throw it out there for reference for any future searches. This was for installation on a 2020 RAM 1500 (DT) which did not have a factory tow package or brake controller installed. I reviewed the e-trailer installation video on a previous Gen RAM and it said the plugs would be right above the gas pedal. At first, I couldn’t find the OEM harness plugs; There weren't any plugs just hanging out in that area.

When I got my package yesterday, I decided to take another looksee.
This time I easily found it. Looking from under, I could see the two plugs snuggly taped together with black material, not electrical, tape. Looking up from my under dash position they were slightly to the left and up. If you have huge hands and forearms, it may take some positioning, and skin cuts, to get to. Luckily I don’t, but took a little finesse to get the tape off. Once I got that off, there was plenty of room to work and plug my adapter harness into.

The brake controller came with a mounting bracket and sheet screws to mount somewhere. Under our dash, there’s a metal dash screw right about the gas pedal that works perfect to mount the bracket. I put on a zip tie as well to make sure it was extra secure. Zip tied the extra slack of the OEM harness and adapter harness under the dash.

Very easy install.

2010 Dodge Ram Pickup

2015 ram 3500 truck.took all of like 10 min. To install and that's just taking my time.the 4 pin plug for the truck is just above gas petal.plug in the adapter to the truck.route the wires how you wish to run them.mount the controller where you wish to mount it which i utilized the panel screw for mine rather than put a hole in my new truck.plug in to controler zip tie the wires and your done.I read forums where people make a big issue out of this.truth is it's nothing to it.plug and go.hope my pics are helpful one showing the 4 pin plug,the mount location, and wires zip tied up.I like the mount type for the primus iq. Wouldn't be no problem swap g it to a different truck.I have not used it towing yet to review that part.maybe I can later


This harness was delivered in a large box with other items. The part itself was in a padded Manila envelope that looked as if it had been delivered by Ace Ventura. The wiring was damaged, which needed to be repaired before use. Unfortunately, I needed to use the harness that day and didn’t have the time to send it back for an exchange.

Thank you for bringing that to our attention! Customer Service should be reaching out to you in the near future.

I love that someone has a head on their shoulders to make the adapter to awesomeness and trailer hauling glory


E-trailer does it right - you don't have to guess around and spend a couple of hours trying to figure out exactly what you need to fit your vehicle.

2019 Ram 1500

Product was exactly what I needed. I sold my old truck with the wire still in it (different make) all I needed a new one for this truck. 5 min of searching and I knew I found the one. 2 day shipping and it arrived on my doorstep. After 10 min of pulling at wires and tape behind my dash I found the right ones. Plugged it in and wham it connected right away (only to tell me I had a broken wire on my trailer brakes, but that's another story).

Good product, fast shipping, A+

2016 Dodge Ram Pickup

We got the controller and wire for a 2016 ram 1500 dealer could not get them but said we had to have the truck program to it I took a chance yours works perfectly on a horse trailer wife is happy for a while I recommend this before going to dealer it would have cost 380 for them to do it thanks


This morning's project,, delivered in three days, perfect fit, one recommendation, secure the hitch with the two factory bolts on each side, then fish the remaining four bolts into place

  • Where Does a Brake Controller Plug Into on a 2015 Ram 1500
    There are so many possible configurations of trucks, including the 2015 Ram 1500, that it is entirely possible that some do not have the brake controller port or harness present. Typically this would be the case on the base model or work truck models that do not have a lot of the features of the higher trim levels. With that being said harness # 3024-P is listed as a fit for ALL models of the 2015 Ram 1500 so it is likely that the connector to plug a brake controller is present on your...

  • Brake Controller Wiring Adapter to Install Reese Towpower Brakeman Controller on 2015 Ram
    The # 20273 brake controller wiring adapter you referenced is compatible with the 2010-2012 Dodge Ram, but because it lacks the diode in the stop lamp switch circuit, it won't work on your truck. You'll need the # 3024-P wiring adapter which is compatible with your Reese Brakeman brake controller. I've edited a photo for you showing where the connector is located under the dash.

  • Locating the Brake Controller Port on 2015 Ram 1500
    The installation instructions for the vehicle specific brake controller adapter # 3024-P indicate that the plug for the brake controller harness is located underneath the dash and to the right of the steering column. The instructions say the plug is taped to another harness and there should be a 4-pin connector that mates with the one of the adapter # 3024-P. Sometimes, these harnesses do not end up in the same exact location on every vehicle of the same model. The connector may be hidden...

  • Troubleshooting Trailer Brake Controller that Only Works with Manual Override Lever
    This is a fairly common problem and the solution is the red wire of the brake controller. Make sure it is connected to a circuit that only sees voltage when the brakes are applied and none when released. Most likely the connection is the issue and just reconnecting the circuit will cause the controller to work again. Typically if the controller is installed with a harness like the part # 3024-P and this problem arises the issue is a blown third brake light fuse on the vehicle.

  • Can OEM Brake Controller of 2016 Ram 3500 be Bypassed with Prodigy P3
    Yes you can bypass the factory controller of your truck with a controller like the Prodigy P3 brake controller part # 90195. You will need the install harness part # 3024-P as well. To install an aftermarket brake controller on a 2016 Dodge Ram that has the factory integrated controller you will have to disconnect the ITBM (Integrated Trailer Brake Module). Doing so will turn on a warning lamp on the instrument cluster. In order to disconnect the ITBM and not get the warning lamp, your...

  • Location of Brake Controller Adapter Port on 2019 Ram 1500
    Every 2019 Ram 1500 has the brake controller adapter port because they use the same plug that Ram uses for their integrated brake controller option. I contacted the tech at Tekonsha that also confirmed that to be true. The dealership may have thought you were asking about the brake controller itself. Even if the Ram did not come equipped with the brake controller the plug is still there. The Tech at Tekonsha owns a 2019 Ram 1500 and he confirmed the plug is underneath the heater controls...

  • Troubleshooting Trailer Disconnected Message on Ram When Hooked Up to Trailer
    It sounds like you have a factory brake controller on your 2018 Ram and you're getting a "Trailer Disconnected" message on the dash when hooked up. If that is the case this error message is usually related to the blue brake output wire that runs from the back of the brake controller to the 7-Way connector. Try and trace the blue wire from the back of the 7-Way on your truck as far up towards the cab as you can and look for any pinched or frayed sections that need to be replaced. The truck...

  • Installing Older Tekonsha Envoy Brake Controller on 2019 Ram 1500 Classic
    The vehicle end gray plug on the Tekonsha Plug-In Wiring Adapter # 3024-P is not available by itself but you can still use this to install the Tekonsha Envoy Brake Controller on your 2019 Ram Classic 1500. You will just need to cut off the controller-end plug on the adapter so that you can hardware it to the pigtail on the Envoy. The wires will match up color to color.

    On the new 2019 Ram 1500 the factory brake controller port is located under and behind the heater controls on the dash. I have attached an image that points to this location. You should be able to access the plug by simply reaching behind and unclipping the panel directly underneath those heater controls. This will allow you to easily remove this small panel so that you can grab the needed plug to which the Tekonsha Plug-In Adapter # 3024-P you referenced will connect. As you can see...

  • Troubleshooting Draw-Tite Activator Only Working With Manual Override on 2019 Ram 1500
    Since your Draw-Tite Activator II works with the manual override but not when you apply the brakes we can narrow the issue down to a problem with the stop light switch connection. Using a circuit tester, ensure that the controller's red wire is seeing voltage only when you press the brake pedal of your 2019 Ram 1500. Check to ensure that wiring is not frayed or somehow damaged and if not, the issue may be with that wire on the controller being faulty as this is an older model that is...

  • Do I Need to Add a Circuit Breaker for Brake Controller When Using a Plug-In Adapter
    Vehicles that can utilize a plug-in adapter will already have fuse protected circuits, so you do not need to install an additional 20 Amp circuit breaker. On occasion, manufacturers have been known to leave out the fuses or the brake controller port, mainly GM, so if you plug in your brake controller and it doesn't turn on, be sure to check all of the trailer/brake controller related fuse locations in your fuse box to make sure a fuse is actually present.
