    • Other end plugs into the back of your electric brake controller

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 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 behind your vehicle's dashboard. The exact location of the plug may vary depending on your year, make, and model of truck.


No hardwiring is required to install this adapter. After you plug it into the factory port, 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 Tekonsha Brake Controller 3031-P Review

Speaker 1: Today we're taking a look at the Tekonsha Custom Wiring Adapter for trailer brake controllers. This plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller. There's no cutting or splicing required. You have the custom connector end that plugs into the built-in port beneath the dash of your vehicle. The other end plugs into the back of your electric brake controller. This is compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha.Just keep in mind that your brake controller must have a built-in plug for the adapter to connect.

This will not work on controllers with pigtail wiring harnesses. The wires also have a really nice mesh jacket that goes around them. It keeps your wires protected and it keeps them grouped together. Then the white wire here that's kind of by itself, has a ring terminal attached to the end of it. This is going to be your ground wire.

That's going to do it for today's look at the Tekonsha Custom Wiring Adapter for trailer brake controllers.

This product makes the installation of a brake controller so easy that almost anyone could do it. If your truck comes with the wiring from the brake pedal to the trailer hitch already installed and you have your brake controller, this is all you need. Plug both ends in and your trailering. 574839

This is the proper unit for a 2018 Tacoma. the hardest part is finding the Factory plug, which is located behind the drivers Kick plate. connect the Ground to the 10 mm bolt that all the Dash connections are made to in the same place. 490874

If you want to make hooking up a controller super easy...this is the way to do it! Get this harness, it'll save you time and a lot of frustration. This went to my 2017 Toyota Tacoma. Plugged it in and screwed down the white wire to ground. Super easy. Hooked up just fine and got trailer brakes as soon as it plugged in. I'd do it again if I ever need to. :) 566265

I purchased the Tekonsha Prodigy P2 for use in my 2016 Toyota Tacoma pickup. I also ordered the appropriate wiring harness and since the truck had the towing package the installation was a breeze. The biggest challenge was finding a mounting location that didn’t interfere with airbags, hood release, reset buttons, yet was still visible and within reach. I found a spot that barely met all the criteria just to the right of the hood release. Everything works as it should and I’m very happy with the controller. It seems to be a well built quality product. I ordered this over the phone and Vanessa at etrailer couldn’t have been more helpful and knowledgeable about some subtle differences in the available wiring harnesses. The product shipped for free and arrived in less than one week. 472255

Great product and service. This item enabled me to just “plug in” my Prodigy P2 brake controller into my new Toyota Tacoma. It was less than a 10 minute job. Most of that time was spent looking for the plastic Toyota panel faster I dropped in my garage. 695744

Well built. Cable was long enough for a driver's side install but not passenger side. White ground wire was long enough to reach a common factory ground point on side behind kick plate.

Was a perfect fit for the 2019 Toyota Tacoma. Coupled with the Tekonsha Prodigy P3 Controller, It almost seems as if it was made for this truck. The unit , with some minor trimming, fit the compartment on the left side next to the steering wheel. Ground wire attaches easily to available bolt/studs with 8mm nut. 683576

Item as described, works as intended, and arrived early. I'd buy it again. I do wish the cable was a bit longer to allow more mounting options, like the center console. When I ordered I didn't really know how long I needed and likely missed details in the item specs. Maybe there's a pre-fab extension cable or a replacement dash panel to accommodate the controller within the length of the cable. 653787

  • Recommended Trailer Hitch Receiver, 7-Way Trailer Connector, and Brake Controller on 2017 Tacoma
  • Sounds like you're trying to build your own tow package on your new 2017 Toyota Tacoma. We can certainly help you with that. We'll begin with the hitch receiver. I suggest the Draw-Tite # 75238. It's a Class III, 2 inch hitch with a gross trailer weight of 7,000 pounds and maximum tongue weight of 1,50 pounds. Higher than a lot of Class III hitches. It's a fairly straight forward installation because it bolts right to your truck's frame. For a wiring harness to get power to your...

  • Plug-In Brake Controller Harness for a 2018 Toyota Tacoma
  • Yes, the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3031-P is a plug and play harness that will allow you to install the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 on your 2018 Toyota Tacoma without any cutting or splicing. You will however need to ground the white wire to a bare metal surface with a self-tapping screw like part # 101131802.

  • What is the Difference Between the Tekonsha Adapters # 3031-P and # 3017-P for a 2017 Toyota Tacoma
  • The only difference between the Adapter # 3031-P and Adapter # 3017-P is that the # 3031-P has an additional white wire for grounding on your vehicle. Both are confirmed to fit your 2017 Toyota Tacoma with the factory 7-Way and will allow you to use a brake controller like the Tekonsha Prodigy P3 # 90195. Out of both of them I recommend going with the part # 3031-P as it is the updated version of the # 3017-P from Tekonsha. If you haven't already decided on a brake controller then...

  • Brake Controller Wiring Adapter Location for 2019 Toyota Tacoma

You will only need to plug it in to the connector underneath and to the left of the steering column; it is behind a kick panel and taped to another harness near the emergency brake pedal, as you can see in the accompanying photo. You have made a great choice with the Prodigy P3 # 90195 because it is one of the most effective and easy-to-use brake...

Since you have not used a brake controller before I recommend something that is easy to use and understand. For that the best option is the P3 # 90195. This controller has a display that actually tells you in words if there is a fault of some kind. Other controllers have codes you have to look up. The P3 also allows you to...

  • If you have a 2017 Toyota Tacoma with the tow package/factory 7-way yes it is pre-wired for a brake controller. For a brake controller I recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.

  • Why Does Brake Controller Harness for 2018 Toyota Tacoma Have Ground Wire
  • That's a common question and the reason Wiring Adapter for Trailer Brake Controllers # 3031-P has a ground wire on it is because some models of Tacoma and Tundra, such as your 2018 Toyota Tacoma, have an insufficient ground at the factory connection and this adapter remedies that potential issue. While there is a wireless option, the Prodigy RF # 90250 I very strongly recommend going with the Prodigy P3 # 90195 which is a better option in every way.

  • We have had the opportunity to install this brake controller on a 2012 Toyota Tacoma. Our installers chose to mount the Prodigy P2, # 90885 to the left of the steering wheel (see photo). On your 2017 Tacoma Sport, the hood release latch and some other electrical controls are in this area, but there is still room to mount the controller beneath them. A taller driver may want to make sure that the brake controller will clear their knee before mounting in this location. If you are willing...

All you will need to do is choose where you would like to mount the bracket for the P3 and then use the Plug-In Wiring Adapter # 3031-P and connect it to the connector under your driver's side dash. Since you have an OEM controller installed it will be the connector that is installed on that. I have attached a video...

  • It looks like you ordered wiring harness # 3031-P which is the correct one for your 2016 Toyota Tundra. But don't confuse it with the harness that comes in the brake controller packaging. The 3031-P harness should have a separate ground wire. That can be attached to any clean, bare metal surface that it will reach. If the harness you received does not have a separate white ground wire then check the tag on it to see if it states what part number it is. Or you can take a picture of it...

  • Can Integrated Brake Controller of 2017 Toyota Tundra Be Replaced with P3

  • Smallest Available Trailer Brake Controller for 2017 Toyota Tundra
  • Most of the better aftermarket trailer brake controllers are pretty much the same general size, that size being larger than your available mounting space which is 2-1/2 x 1-3/4-inches. The excellent Prodigy P3 # 90195 that you referenced measures 3-5/8" wide x 4-5/8" long x 1-3/8" tall. The Voyager # 39510 measures 3" wide x 5" long x 1-1/2" tall and the Hopkins Agility # HM47294 measures 3" wide x 5" long x 1-1/4" tall.

  • Which Brake Controller Install Harness Is Needed for Installing Controller in 2017 Toyota Tacoma
  • The part # 3031-P is designed to replace the part # 3017-P as it is the latest design. Basically the 3031 has an additional ground wire that allows the controller to perform better. So to install the Tekonsha PowerTrac # 39523 I would recommend the # 3031-P for your 2017 Toyota Tacoma.

  • Recommended Brake Controller and Install Location for a 2017 Toyota Tacoma
  • The best place to locate a brake controller is, like you said, out of the way, but also in a spot that is easy for you to activate the manual override switch in case of an emergency situation. Most people mount the controller on the underside of the dash just to the left or right of the steering wheel on the driver side. Since pretty much every brake controller is relatively the same size (about the size of your hand) I recommend going with the Tekonsha Prodigy P2 # 90885. This is a...

  • Difference Between Brake Controller Install Harness # 3017-P and # 3031-P for Toyota Tacoma
  • Technically they both fit your 2017 Toyota Tacoma and the P3 Brake Controller # 90195! The difference is that the # 3031-P is replacing the # 3017-P as it was designed with an extra ground wire which allows the harness to function better.

The overall dimensions not counting the wires at the back are: 4.25 inches front to back, 2.81 inches wide, and 1.18 inches tall. In addition to the brake controller you will also need # 3031-P to plug it into your 2018 Toyota Tacoma.

Put the power to the highest setting and then use the manual override to send power along the blue wire to your trailer brakes. If the blue wire on the PowerTrac isn't sending power but it is receiving power on the black wire then the controller is bad and you need to replace it. The PowerTrac and the Voyager # 39510...

  • How to Mount Prodigy P2 part # 90885 in 2017 Toyota Tacoma
  • The P2 # 90885 must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly. For an install harness in your 2017 Toyota Tacoma what you need is the part # 3031-P. Most people install the controller on the lower dashboard of the vehicle to the right of the steering wheel where it wouldn't interfere with you right leg.
