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.

My Tekonsha P2 & wiring kit 3031-P for my 2017 Tundra Crew Cab arrived timely and installation was SUPER EASY. Connected my 27 foot trailer the same day to test it. Works awesome. Disappointed in Toyota for having a poor Brake Control System, but thankful Tekonsha was able to pick up the slack.
by: Jim S.07/14/2020
Get this cable for a simple, plug-in installation. You’ll spend more time hunting for the junction already wired into the truck harness than installing your brake controller. And after installed, no worries on loosening wire connections or electrical tape wrap unraveling.
by: DonnaMarie09/11/2023
I used this to connect a brake controller, ITEM TK63VR, to the brake harness under the dashboard of my husband's 2022 Toyota Tacoma SR5. It worked excellently and was very easy to do because the ends just snap right into the harness and the little ground wire fits right under the grounding screw. eTrailer's instruction videos are great, thats why this ol' grammy was able to do it herself! Thank you etrailer! PS I just wish that it was a foot longer.

Wiring harness 3031-P on a 2015 Toyota Tundra, doesn't get any easier. I have cut and spliced several brake controller over the years. This is a lot cleaner and very easy.
by: John04/29/2024
Day after I ordered this part I was contacted by the company to say that the part wouldn't be shipped for several weeks and they worked to get me a replacement solution. This ultimately did not work out but their customer care was something that has become a rare thing these days. I think the sales agent whose name I do not recall at the moment and a few days later got a notice that the original part I ordered was out for delivery. It arrived today I installed it in my vehicle and everything works perfectly. I would definitely do business with etrailer again for my RV needs. Thank you guys.

The wiring harness is exactly what most folks need for an under dash or dash mount. I found that it was more convenient to access the brake controller emergency handle and see the brake controller if I took your metal mounting bracket and turned it upside down and mounted the controller on the left hand side of the steering wheel on top of the dash with a magnet taped to the dash. This allow me to remove the controller and move it between my Tacoma and Ford F150 easily. But in order to do this you need a longer wiring adapter, so you either cut the original wiring harness and splice in longer wires or buy two harnesses and cut off one end of each and splice that together. Very happy with both the harnesses and the Tekonsha P3 brake controller.

Installed my old Tekonsha P2 controller easily in the new truck in about an hour. Wire was just long enough to reach the preferred spot. Fantastic service as usual.
by: Karen07/06/2023
We love our Tekonsha brake controller. Works great on our 2018 Tacoma while pulling our 1025r John Deere subcompact tractor.
by: Reginald03/12/2020
Everything came in the package and the product came earlier than I expected. Installing it was fairly easy. However the only thing that proved difficult was Torquing the ball down on the hitch head which luckily [RV dealer] was good enough to do that for me. I am happy With the product and looking forward to using it.

Fit perfectly. did not have to cut into vehicle wiring harness and super quick install

2018 Toyota Tacoma
The cable fits the desired application on my 2018 Tacoma. A couple of inches longer would have been nice - it was barely long enough for where I mounted the controller. The location shown in the pic was the only location that didn't get in the way of of knees, feet or air bags. By the way, the other item in the cubby is my ham radio faceplate.

Easy installation. This unit is the best controller I have ever had. I utilized my existing inset compartment and just cut off the back of the compartment til I had about 2” remaining from the front flange to minimize the amount of space around the P3 controller when installed to have a better appearance.
by: Matt 02/13/2024
Excellent fit and function.

Great product and super easy to install with the adapter.
by: Alex 09/22/2020
to be honest I bought this harness to modify it. I needed the plug that goes into the OEM port on the truck so I would not have to T Tap power to run accessories I simply would tie in my switches to this port to use for what I want. I still have not completed the install.

Works fantastic, no problems, brakes the trailer with proper amount related to truck braking.
by: Donald 03/31/2023
Made the install that much easier, take your time pulling off the side cover to get to the wiring harness. Seems like the bottom front plug gave me the most trouble but love how much difference trailer brakes while pulling a heavy load make.

- What Angle Should Prodigy P3 Brake Controller be Mounted at When Installed in 2018 Toyota TacomaWhen you go to install the Prodigy P3 part # 90195 in your 2018 Toyota Tacoma the controller has to be level from side to side and face directly towards the rear of the vehicle so that the inertia sensor of the controller can get an exact reading on how much braking pressure you are applying and then apply a relative amount to the trailer's brakes. The install harness you need then is the part # 3031-P which plugs into the back of the controller and then into the port under the dash of...

- Brake Controller Install Harness for 2019 Toyota Tacoma to Install Prodigy ControllerThe correct brake controller install harness you need is the part # 3031-P for a Tekonsha controller like the very popular P3 # 90195. The harness you would have had in a 2015 Tacoma would have been the 3040-P which is different.
view full answer... - Recommended Brake Controller for 2018 Tundra with Factory Integrated Brake ControllerFor your 2018 Toyota Tundra, the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In # 3031-P may plug into your Tundra but according to my tech contact it will not work based on their testing. Even though Curt carried their harness over he can't confirm it works as their testing only showed the port as a data port and doesn't provide the same functions needed. He said based on their fit on 3 separate attempts direct wiring like the # ETBC7 is the only option for...

view full answer... - Recommended Trailer Hitch Receiver, 7-Way Trailer Connector, and Brake Controller on 2017 TacomaSounds 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 Curt # C13264. It's a Class III, 2 inch hitch with a gross trailer weight of 6,000 pounds and maximum tongue weight of 900 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 trailer...
view full answer... - Idea for Mounting Location for Brake Controller for 2021 Toyota TacomaI looked up pictures of the interior of your 2021 Toyota Tacoma and it is pretty tight but it looks like there's a cubby hole area in front of the gear shifter that you could fit the Tekonsha brake controller # TK90160. The correct install harness is the # 3031-P.
view full answer... - Wiring Adapter for Tekonsha Brake Controller in 2017 Toyota TundraThe correct wiring adapter for your 2017 Toyota Tundra and a Tekonsha brake controller is the Tekonsha Custom Wiring Adapter # 3031-P which will work with your truck and brake controllers such as the Prodigy P3 # 90195, Prodigy P2 # 90885.

The linked video also shows where the connector is located. We take all of our own product photos here, so what's shown in the product description photo is exactly what you'll receive, which includes all the mounts and mounting hardware.

- Brake Controller and Install Harness Recommendation for 2016 Toyota TacomaThe correct brake controller install harness to use with a Tekonsha brake controller like our very popular P2 part # 90885 is the # 3031-P. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. 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.
view full answer... - Does 2020 Toyota Tacoma Need Brake Controller to Activate Travel Trailer BrakesYes you do need a brake controller installed in your 2020 Toyota Tacoma to control the travel trailer's electric brakes as there isn't one installed in your truck from the factory and there's no other device that can actuate the brakes. To do that you'd need a brake controller like our very popular Brake EVN part # TK63VR with the install harness designed for it and your truck part # 3031-P and you'd be set. The I-Command is so popular because of how well it works, how reliable it is,...

You will need part # 3031-P. This plugs into the harness that can be found at the top of the carpet just to the left of the brake pedal. It may be taped to another harness in that location or tucked up under the dash making it a bit tougher to find. I verified this with my contact at Tekonsha. If you have another brand brake controller let me know and I will...
view full answer... - Which Tekonsha Brake Controller Install Harness Fits 2019 Toyota TacomaTekonsha does have a brake controller install harness that fits your 2019 Toyota Tacoma with the # 3031-P but the # 3040-P does not fit. This will work great with the P3 brake controller part # 90195 which many refer to as the best brake controller out there.

view full answer... - Brake Controller Install Harness Recommendation for a 2015 Toyota TundraYou are going to need the Tekonsha brake controller harness part # 3031-P. The white end of this connector will plug into the port under the dash of your truck and then to attach the harness to your brake controller you will need to cut off the black end and hardwire it to your controller. Hopkins doesn't have a harness at this time for your vehicle, but this harness will work just fine.

view full answer... - Comparing Prodigy P3 and P2 for 2017 Toyota TacomaIf you have never used a brake controller before, the P2 # 90885 will be easier to learn on and use than the P3, # 90195. The P3 has several features the P2 doesn't including the ability to change the LED screen color, change the language, and the biggest difference is the diagnostics. Instead of flashing a code you would have to look at the P3 has clear messages telling you what the problem is. Other than that the controllers function in the same way and mount in the same way. I have...
view full answer... - Why Does Brake Controller Harness for 2018 Toyota Tacoma Have Ground WireThat'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 are wireless options like the Curt Echo # C51180, I very strongly recommend going with the Prodigy P3 # 90195. The P3 is easy to use, levels automatically, has constant diagnostic...

- Smallest Available Trailer Brake Controller for 2017 Toyota TundraMost 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.

view full answer... - Best Trailer Brake Controller For a 2019 Toyota Tacoma Towing a 3,500LB 2017 Riverside TrailerThe weight rating at which a brake controller is required will vary from state to state, but you should definitely be using one with your 2017 Riverside trailer that has a dry weight of 3,500lbs. I recommend that if you operate a trailer has electric brakes you should use a brake controller. For your 2019 Toyota Tacoma I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195. This controller is proportional so that it will automatically adjust the trailer brake output based...
