Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.


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.

Video Transcript for Trailer Brake Controller Wiring Colors

Today we are going to cover a frequently asked question. It really turns up a lot. And actually it is easier than you think. Basically, if you have a pickup and you got a tow package with it and you got one of these wire harnesses that plug underneath the dash and plugs into your brake controller, you might have five or sometimes even more wires coming off of it. And you notice that your brake controller only uses four. We have got one over here, we will show you, that has just the four wires and what do you do with the extra wires? The short answer is do not worry about it, because the brake controller has all that it needs from these four wires.

To give you an idea of what is going on, most of the time these harnesses are labeled as to what color does what. So this one will say TO TRAILER ELECTRIC BRAKE. That means that this is going out to the trailer itself. So if you look on the your brake controller, it is going to be the blue wire here, so those match up together just like that. The next one is labeled GROUND, so you go to the wire harness on your brake controller and find the one that is labeled GROUND in this case it is going to be white, also. And then the next wire, here, we do not have a label because the label fell off, but this is the 12 volt power supply wire here. A lot of times the brake controllers come with a little handy card that tells you what does what on the OEM harnesses, also. The thicker wire is usually going to be your power supply. So that would go to black, the 12 volt power supply wire on the brake controller.

Then you have the two wires left, the green and the brown. The green is labeled STOP LAMP, so that will go to the stop lamp circuit on your brake controller, which in our case will be red. And then you have the extra wire here, which is labeled ILLUMINATION FEED. Basically, this comes on when you turn on your running lights. So if you have something you need to power on the inside of your vehicle, for running lights you could possibly use this. But for towing purposes, I do not really know really what you could use this for no brake controller ever uses this. So basically all you do is just fold it back out of the way, tape it up so it doesnt short out against anything, and do not worry about it.

I purchased the Tekonsha P-3 and the plug and play harness for a 2006 Dodge ram. Cathy of etrailer was very helpful. I was concerned about shipping and Cathy promised that she would get it out that day. Sure enough I got a follow up e mail letting me know that it went out that day. I even got an e mail letting me know that it has been delivered. Outstanding customer service! 31726

I purchased a P3 brake controller and wiring replacement for my dodge ram truck from E-Trailer and could not be happier with the service and the products. My order was delivered very quickly. The wiring replacement was as good as the OEM part that originally came with the truck. Installation was plug and play once I decided where I wanted to place the bracket for the controller. If this 53 year old lady can do it, anybody can. It was easy. I might add that I shopped around to see what I could get this same controller and wiring for locally and the cheapest was over $100 more than I spent for the same components from E-Trailer!7615

The product shipped fast. Simple plug and play wire harness. No splicing, just plug in and hide the cords. The vehicle I put it in already had factory 7-pin so the plug was right under the dash. I love wiring kits. 30 sec instal time. 10 sec if I would have used a flash light.104762

I had the benefit of having a factory installed tow package on my 2006 Dodge Ram 1500 pick up. With that being said, I was still unsure of if what I saw online would work. I contacted etrailers.com via email and they answered all my questions and concerns within a few emails. I bought the product and install extremely easy. My only complaint is that the cable is not very long. Approx 3ft or so. But other then that, it works great and help me tow my bobcat on my 16' trailer with ease of stopping.103305

While the P3 manual was not easy to follow the unit was eay to install and pretty much set itself up. Worked great - no adujstment time needed it handled the trailer as if I wasn't towing anything. This is my first time towing and first time owning a trailer - it couldn't have been easier. Would highly recommend this to anyone ! 102429

This made hooking up the 90185 controller to my 08 Ram a breeze. Couldn't have been easier. Only one minor complaint, and that is the cable should be longer. Extra foot or two would earn this an excellent rating.96777

Ordered product, and was shipped out the next day. Got in mail a few days later. Very easy install, I removed the old brake controller and installed the wiring adapter (just plugs in under the dash). Mounted controller to metal mounting bracket. This controller works great, I am very familiar with other controllers, I really like the proportional braking, brakes work great on my landscape and dump trailer. I tried light braking to heavy braking, adjusts properly and quickly to situation, no lockup with empty or loaded trailer. I pull trailers 5-6 days a week and I am glad to have a working brake controller again. Very satisfied with this product, just hope it lasts longer than the other brand I installed.95931

I installed the electronic 3020-p break controller with the harness for a dodge ram in about 20 minutes. It was about as easy as it could be with the correct products from E-Trailer. I have not hooked up to my travel trailer as yet but foresee no major problems after reading the supplied directions for doing so. Thanks again. I could take pictures of the installation but don't know how to attach and send them to you. Thanks for great products.95537

My previous controllers came with a pig-tail type of connection which required tapping into existing wiring. This one was configured specifically for my 2003 Dodge 3500 Ram dually. Once I found the connecting plug under the dash all I had to do was plug this one into it and to my new Tekonsha P3 and I was done. 54678

Installation was a breeze, I used it last sunday towing my stock trailer, the digital display is nice. The gal I spoke to at etrailer was very helpful for me while deciding which controller to install. I regularly tow a 16' steel stock trailer as well as occasionally tow brick and masonry materials, the p3 proportional was a major step up from my old school drawtite electric controller. The self leveling feature of the p3 has already been helpful for me. I am pleased with the product. 42792

This is the second time I've ordered products from Etrailer. They shipped the products extremely quickly (both times) and I received them substantially earlier than expected. I previously ordered a Prodigy brake controller and all the parts needed to do a full install, since my truck was not wired for a trailer. I just purchased a 2006 Ram 3500 and used this cable to connect to the factory harness. It worked as advertised and I was able to reuse my exisiting controller without any problems. I will definitely be using Etrailer for future purchases based on their excellent customer service and pricing.22503

Installed on a 06 Dodge 3500 Mega Cab. This is as advertised, but it's only about 24 inches long. If you want it to reach the center console you will need to splice in about 12 - 16 inches of more wire, but it's still much easier than splicing the factory wires under the dash.9866

  • Wiring a Brake Controller and a 7-Way Connector On a Dodge 2500
  • With the factory 4-Way connector you will need a brake controller with the proper wiring connection for Dodge vehicles. I would recommend the Tekonsha Prodigy, item # 90185-3020P, for your vehicle. This package comes with the vehicle specific brake controller connector. You will also need a 7-Way, item # 30717, adapter. With these parts you can use the specific instructions on our brake controller wiring page for 1995-present Dodge Ram trucks (see link).

  • The Tekonsha Brake Control harness, part # 3020-P, is designed to fit Dodge/Chrysler vehicles equipped with a factory tow package that includes a brake controller port underneath the dash. The Magnums did not get these tow packages. You can still use a brake controller, but you will need to do some wiring since you do not have the brake controller port. There are 4 wires on most brake controllers; white, black, red and blue. The white is a ground wire and should be run to the negative termina

I am sending a video link of a brake controller installation on a 2003 Dodge Dakota and at the 45 second mark it shows the location of the brake controller port under the dash that should help you locate the port on your vehicle.

Instead, you will need to hard-wire the brake controller using the Brake Controller 7 and 4 Way Installation Kit, part # ETBC7.

Since you do not have the factory 7-way, your Dakota does not have the tow package and the brake controller will need to be hardwired into the truck. You will need a brake controller (which according to your order, you already have) a functional 4-pole trailer connector on the Dakota l

  • Why Does a Trailer Brake Controller Stay On when the Key is Turned Off on a 2002 Dodge Ram 2500
  • I am not sure which brake controller you are using but most controllers are connected to a fused power source directly to the battery and not an ignition source. This means the controller can draw power even with the key off. However, most will go into a kind of sleep mode after about 15 minutes of inactivity and will not draw much if any power from the vehicle battery.

  • Parts Needed to Add a Trailer Brake Controller to a 2000 Dodge Dakota
  • It sounds like your 2000 Dodge Dakota did not come with a factory towing package. In order to install a brake controller it will need to be hardwired. Since you have a 7-Way connector, look to see if there are 7-wires that all lead to somewhere or if there are only 3 or 4. The truck may have had a 4-Way installed at some point and someone added the 7-Way later to match a trailer they were towing. If this is the case then you will need a brake controller installation kit # 5505 for 2 to 4

  • Wiring 2000 Dodge Dakota for Brake Controller

I am unaware of anything a dealer might offer that would change this. Without the under-dash connector, the brake controller would need to be hardwired into the existing vehicle wiring using our Brake Controller Installation Kit, part # ETBC7.

It will be used if you have the factory 4-Way or the factory 7-Way on the rear of your vehicle.

  • Can an Aftermarket Brake Controller be Installed on a 2012 Dodge Ram 2500 with Factory Controller
  • Yes, there is a plug and play harness to install an aftermarket controller on a 2012 Ram with the factory controller but there are a few things to do first. I have explained it below and also included a link to an FAQ that will help. To install an aftermarket brake controller on a 2012 Dodge Ram that has the factory integrated controller you will have to disconnect the ITBM (Integrated Trailer Brake Module).

  • Locating Blue Wire On Motorhome When Installing Brake Controller
  • Larger motor homes typically do not come with the brake controller wiring installed. The first step I would take is to make sure that the connector you found on the motor home under the dash is indeed for a brake controller. If the connector on the motor home matches the connector you purchased, then you should be able to plug in the harness and test the pins for the black and the red wires using a circuit tester like part # 3808. The black wire should show 12 volt power all the time, and the re
