  • Trailer Brake Controller
  • Wiring Adapter
  • Tekonsha
  • Wired to Brake Controller
  • Vehicle Specific

Streamline the installation of your trailer brake controller with this custom adapter. Simply connect the wires of the harness to your brake controller and then plug the other end into the built-in port beneath your vehicle's dash.


Features:

  • Pigtail wiring adapter eases installation of your electric trailer brake controller
  • Connector end plugs into the built-in port beneath the dash of your vehicle
  • Wire end connects to the wires on your brake controller with the included butt connectors
    • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
  • Limited 1-year warranty


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 5-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 hook this adapter up to your trailer brake controller, just connect the 4 wires of the harness - ground, power, brake switch, and brake power - to the corresponding wires on the brake controller. If your brake controller came with a plug built into its wiring harness, you will have to cut off the plug and connect to the wires themselves.

We use our Redarc tow pro setup every time we take our offroad trailer camping. The trailer is not heavy but when we are offroad and navigating technical trails it is so nice to have a little more control of the trailer and how it handles. Having the dial makes it so easy to adjust as we are traversing a trail and the 3 axis controller always performs properly even on off camber situations 801206

Great product, had it in the truck for almost a year now. Plug and play, with no splicing into the Tundra harness. As shown in photo, a bit of careful drilling and dremelling, I used one of the blank switch locations to locate the controller knob and be able to show the indicator light. 771019

One of the few brake controllers that allows you to "remote mount" the control unit. Allows for a super clean install that looks like its from the factory rather than having to bolt an obnoxious brick somewhere on your dash only to smash your knee into it anytime you get in your truck. And the actual brake control woks great too! The user interface/control knob is easy to use and provides a simple way making adjustments to the controller. I'm able to easily test the trailer brakes with the push of a button and set the brakes how I want them to function. Installed on a 2012 toyota tacoma. 703766

I had great anticipation for the delivery and going over the install instructions it was simple install. My biggest worry was trying to make it look clean, 2012 tundra already had tow package so I purchased the specific wire pigtail, so after removing lower dash removing pop out in dash- thanks Toyota- a little work with a Dremel tool for the redarc brake controller in dash install looks EXCELLENT, total install time for me was about 2 hours 672287

My dealings with etrailer have been a very positive experience. It started with a direct conversation with one of etrailer's sales reps over the phone. He was knowledgeable and respectful. I ordered the product per his recommendation. When the product arrived, I was able to simply plug it into the existing wire harness in my 2003 4x4 Tundra. I followed the instructions on how to install the unit and adjust it to the proper settings without a problem. I have an Iron Bull 5'x10' dump trailer I use all the time and the bake control I purchased from etrailer has actually exceeded my expectations. I'm up and down the Feather River Canyon weekly and I can easily adjust the control unit using the thumb wheel to address the different load weights I happen to be pulling. For the record I so appreciate the fact etrailer allowed me to actually use the product for a year before asking for my feedback. That's how it should be if the seller (provider) wants valid and reliable feedback. Great job etrailer. 725906

I ordered these items online with the help of etrailer.com tech support and got the right parts the first time for my mechanic to install on a 2003 Sequoia Limited 2WD. Item 3040-S was installed in conjunction with the Tekonsha Prodigy P3 trailer brake and worked perfectly, and out of the way. With the included bracket i’m able to disconnect and remove the controller from the hot vehicle. 665356

If you have a Tundra and need to install a brake controller this is a must. It plugs directly into your factory plug underneath the kick panel so you don’t have to run any wires to the rear of the truck 655311

  • Which Tekonsha Brake Controller Install Adapter Fits 2018 Toyota 4Runner
    The adapter you need is actually the part # 3041-P which is correct for your 2018 Toyota 4Runner. You'd have to cut off the black connector and then splice the colors of it to the wiring of your brake controller.

  • Compatibility of Tuson DirecLink Brake Controller # 335DL-100 with 2006 Toyota Tacoma
    I spoke with my contact at Tuson regarding the DirecLink Base Model Trailer Brake Controller # 335DL-100 and your 2006 Toyota Tacoma. The potential issue with regards to fitment for this controller on trucks prior to 2008 is that not all of them are equipped with the factory 16-pin OBD-II port under the dash that this hooks up to. Many previous model year trucks do have this port but many do not, making it difficult to confirm fitment accross the board which is why Tuson lists compatibility...

  • Recommended Brake Controller and Wiring Harness for 2012 Toyota Tundra Console
    The Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers - Toyota and Lexus # 3040-P is a great option for Tekonsha brake controller wiring in the traditional location. However, because you desire the controller to be a part of your console, there are better options available for that fit. I recommend the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - Toyota # 3040-S along with the Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2 which...

    Since you will be pulling your trailer full time with your 2013 Toyota Tundra you are definitely going to want something that is effective, easy-to-use and doesn't take up space in your truck's cab. The perfect brake controller for you and the one I strongly recommend is the Redarc Tow-Pro Elite Trailer Brake Controller # 331-EBRH-ACCV2 because it meets all of the aforementioned criteria. To install this controller in your '13 Tundra you will need Custom Wiring Adapter # 3040-S; if...

  • Brake Controller Recommendations for a 2007 Toyota Tacoma
    If you're looking to do a simple upgrade to your original Prodigy brake controller then I recommend using the Prodigy P2 # 90885 or P3 # 90195. These are both just more recent models of what you have and the P3 is the only controller that I know of which uses an LCD screen to make it easier to adjust settings and troubleshoot (when the need arises). To install either of these on your 2007 Toyota Tacoma it's going to be just a matter of unplugging the pigtail at the back of your Prodigy...

  • Recommended Wiring Harness for 2004 Toyota 4Runner Limited & Redarc Tow Pro Elite Brake Controller
    The trailer connectors are a standard size but there are two styles of 7-way connectors. For camping trailers the traditional 7-blade is by far more common than the agricultural 7-pin. Your trailer is likely all set to work with your 2004 Toyota 4Runner. To add the brake controller I recommend using the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - Toyota # 3040-S for the Redarc Tow-Pro Elite Trailer Brake Controller - 1 to 3 Axles - Proportional # 331-EBRH-ACCV2.

    The Redarc Tow-Pro Elite Trailer Brake Controller - 1 to 3 Axles - Proportional # 331-EBRH-ACCV2 doesn't disclose their hardware/software upgrades. They simply have the Tow-Pro Elite as an upgrade from the Tow-Pro Classic. It comes with the manufacturers most recent upgrades as this braking system is their most recent option and it is my personal favorite out of everything we carry. It has adjustability that others do not, has a clean look, LED codes, and many mounting location options....

  • Wiring Adapter to Install Redarc 331-EBRH-ACCV2 Tow Pro Elite Brake Controller in 2017 Lexus GX460
    To install the Redarc # 331-EBRH-ACCV2 Tow Pro Elite in your 2016 Lexus GX460, you'd need the # 3040-S brake controller wiring pigtail. The 3040-S would wire up color for color to the universal pigtail provided with the brake controller. You are absolutely correct, the factory brake controller connector is located right next to the e-brake. For those that don't care to have the typical brake controller box installed on the underside of the dashboard, the Tow Pro Elite is definitely the...

  • Trailer Hitch and Trailer Wiring for 2017 Lexus GX460
    From your photo, it looks like you already have a 4-pole/7-way trailer trailer connector on your Lexus GX-460 that's identical to the # HM40975 we offer. This means that if you're towing a trailer that does not have electric brakes, you're good to go once the # C13043 hitch is installed. If the trailer does have electric brakes, you'll need to install a brake controller if you'd like them to actuate. I'd recommend the Redarc Tow Pro Elite, part # 331-EBRH-ACCV2. You'll also need the...

To connect this to your 4Runner you just need the adapter # 3040-S. If you live in California you also need the Adapter # 30235-P.

The # 3040-P is compatible with all Tekonsha brake controllers that have either the socket in the rear of the controller for the harness or those that have the wires that extend from the rear of the controller that terminate in a connector.

The Elite has the ability to be the more preferred proportional style of controller as well as a time-delayed whereas the Liberty gives you just the proportional setting which is what you'd want to use with your towing setup. Proportional controllers sense how hard you are applying the vehicle brakes whereas time delayed means it puts a preset...

However, we have not yet had the chance to install a 7-way on a 2013 Toyota Tacoma with this same setup so I would not have any exact locations to look for these wires.

Without it you would need to install a 4-way connector # 118496 and the Universal Installation Kit for Trailer Brake Controller # ETBC7, which will give you all the needed components to add a brake controller to your Tacoma.
