Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 6-pin connector on your vehicle's built-in brake control wiring harness. Older models will have the harness located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. Newer models have the harness under the dash, above the gas pedal.

To install your electric brake controller you need to connect the four wires - ground, power, brake switch and brake power - 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 you do not have a harness, or you need a new one, the Tekonsha wiring adapter will serve the same purpose.

Tekonsha Wiring Adapter for Electric Brake Controllers - Nissan - 3050-S

Average Customer Rating:  4.9 out of 5 stars   (26 Customer Reviews)

Ease installation of your electric brake controller by using this custom wiring adapter. Simply connect the 4 wires of the harness to your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.


Could not have worked better! Perfect fit, good heavy gauge wiring with thick insulation. Wires within a "cage" conduit. Plenty of length to allow attaching trailer brake controller anywhere it needs to go. Very pleased with this purchase! In the photo, you can see just a bit of the 3050-s (upper left corner) where it connects to the rest of my "system".


Plug n play on my 2018 Nissan frontier with a redarc tow pro elite.


I recently bought the Redarc Tow-pro Elite Break controller and the harness adapter to match my 2018 Armada Platinum. I also choose expedited shipping since I had our first camping trip booked only a few days away! It showed up on schedule early in the day, installation took less then an hour from initially opening the box to completion. The harness adapter made installation incredibly easy, and the redarc control knob looks good mounted (which I was previously worried about installing in my dashboard). I’ve logged several trips already, set up was easy as well as fine tuning the brake intensity. Great product!

2014 Nissan Titan

I recently purchased a 16X6.4 tandem axil trailer and needed to install a good brake controller in my 2014 Nissan Titan for it. I found etrailers web sight and after looking around for a bit found the exact controller I wanted. Their web sight made it a lot easier then I thought and they had everything I needed including the correct harness. I even called just to make sure and the person I spoke to on the phone not only assured me I had the right items but also took my order. The whole process took less then 10 minutes. I received the controller and harness in just a couple days and everything was correct. Installed it in the truck and Walla!! I have brakes on my trailer and they work great. If there is ever anything else I need for this trailer in the future I will be paying these guys a visit.

2004 Infiniti QX56

I already had a Tekonsha Voyager Trailer Brake controller which had pigtails. Added this wire harness and four (4) butt splices and I just plugged it into my 2004 Infiniti QX56. Great.


Worked great. Probed the wires just in case, but the wire colors on the adapter matched the colors on the brake controller. The yellow crimps were a little larger than needed. Had to REALLY crimp them down to hold the larger gauge wires on the adapter.


Extremely good quality parts and harnesses. I needed them by a specific day and it was very important that I got these for a camping trip we had planned for months, they were at my door exactly when promised. The sales staff on the phone were especially courteous and patient, also eager to answer my questions and double checked MY order for correct fitment to ensure a perfect experience. I never do these online reviews but I was impressed enough to sit down and do this. Can't wait till I need trailer parts again, I'll shop here without a second thought.

2011 Nissan Titan

The wiring harness I ordered from Etrailer came in a timely manner and it plugged directly into my Nissan Titan. I am very pleased and it has met all my expectations!


Couldn't have asked for a more simpler, affordable way to get a brake controller. The OEM ones are way over priced. This connected in perfectly with no hard wiring necessary. If I can install it anyone can.

Nissan Pathfinder

Wire loom didn't go the full length of the wires. Butt connectors are not the correct size. Fit my Pathfinder without issues.


Easy to install and tremendous savings over buying factory nissan harness.


Product arrived as described and greatly helped the installation of my brake controller.


Went together easily. Good directions. etrailer comes through again.

2016 Nissan Pathfinder

Great product at a great price! It fit my 2016 Nissan Pathfinder perfectly!

  • New Install Wiring Harness for Tekonsha Brake Controller in 2012 Nissan Frontier
    Depends on what brake controller you have, but if you look at the back of your brake controller and you see what looks like an L-shaped connector where the wires all plug into which then plugs into the back of the connector you can simply replace that with the # 3050-P. Otherwise you'd have to use the # 3050-S to hardwire the controller to a connector compatible with your 2012 Nissan Frontier.

  • Brake Controller and Install Harness Recommendation for a 2015 Nissan Frontier
    For your 2015 Nissan Frontier the recommended install harness to use is the # 3050-S if you are wiring up a brake controller that has 4 blunt cut wires. Or if you go with a Tekonsha controller like the P2 part # 90885 you would want the # 3050-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...

    To attach the Draw-Tite Activator IV, item # 5504, electronic brake controller to your vehicles factory connector you will need a Universal Brake Control Wiring Adapter, Nissan, item # 3050-S. This adapter has four wires that attach color for color to the wires on the brake controller. If you have an adapter that plugs into your vehicle that has five wires then you will have to use a circuit tester, item # 3808 if you need one, and verify the function of each wire once it is plugged in.

  • Troubleshooting Reese Pilot Brake Controller Installation On a 2006 Nissan Titan
    It sounds to me like the wiring harness for installation of the brake controller may be pinned wrong. First, make sure the you spliced the like color wires from the Pilot brake controller, # 80550, to the wiring harness, # 3050-S, for your 2006 Nissan Titan. Next, make sure you have the correct wiring harness for your truck. Since the connector is plugging into the factory connector on your truck you might just need to re-pin the connector.

  • Wiring Adapter for a 2005 Nissan Frontier and Hopkins Agility Brake Controller Installation
    Most likely, the 5th wire is for illumination. None of the brake controllers we sell have this feature. But it is not needed to install a brake controller, including the Hopkins Agility Trailer Brake Controller, # HM47294. The wires on the Reliance brake controller are as follows: White is the ground. Blue connects to the trailer brakes via a 7-Way connector. And Red is the stop light that connects to the switch at the top of the brake pedal. Black is the 12 volt hot lead. The simplest...

  • Recommended Brake Controller and Wiring Harness Location for a 2018 Nissan Armada
    I recommend installing the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR on your 2018 Nissan Armada because it offers both a user-control mode and a proportional mode for varying towing applications plus it installs in such a way that only the control knob will be visible. This combination gives you a great brake controller and a clean looking installation that won't get in the way. The user-control mode is equivalent to a time-delay controller where it brakes at a preset strength...

  • Installing Redarc Tow Pro Elite Brake Controller on 2016 Nissan NV 3500 with Factory Tow Package
    On your 2016 Nissan NV 3500 that's equipped with the factory tow package you can use the Wiring Adapter # 3050-S to easily install the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR. The plug end of the adapter will connect right to the factory port behind the dash of your NV 3500 and the pigtail end will just splice into the wires from the brake controller (color to color). I have attached a short video review of the Tow Pro Elite that you can also check out, along with the...

  • Brake Controller and 7-Way for 2017 Nissan Frontier Without Factory Tow Package
    It sounds like your 2017 Nissan Frontier does not have the factory tow package since you are in need of a 7-way (which is what I believe you are referring to by 7-prong connector) and we do have the parts you need. To start with, you will need to add a 7-way with the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. I have added a link to an installation video of this harness for you to check out on a '17 Frontier. Then for a brake controller I highly recommend the...

  • Parts Needed to Add a Brake Controller to a 2012 Nissan Murano
    A brake controller will have to be hardwired to a 2012 Nissan Murano since there are no brake controller wiring harnesses designed to fit it. To do this you will need a few parts and the brake controller. First, if your Murano does not already have a trailer connector you will start by installing a 4-Way using # 118653 for the regular Murano or # 119190KIT for a CrossCabriolet model. Once the 4-Way is installed or if the Murano already has one you would then install # ETBC7 which includes...

    If you have an area that measures 1 inch wide by 1-1/2 inches tall to install the Universal Mounting Panel for Redarc Tow-Pro Elite Trailer Brake Controller Control Knob # 331-TPSI-001 it would work well for you, but we don't have a specific fit for this product on your vehicle.

  • Is Aftermarket Trailer Hitch Safe to Use Over OEM Trailer Hitch for a 2017 Nissan Pathfinder
    Yes, even though the Draw-Tite Max-Frame Trailer Hitch Receiver # 76031 only uses 6 bolts as opposed to the 10 bolts for the OEM trailer hitch it has gone through an extensive amount of stress tests to ensure that the 6,000 lb trailer towing rating is completely safe. I highly recommend going with this over the OEM for your 2017 Nissan Pathfinder so that you can add some extra components. For a cost-effective brake controller that is reliable I recommend the Tekonsha Primus IQ # TK90160....

  • Recommended Brake Controller for 2018 Nissan Titan With Factory 7-Way
    For your 2018 Nissan Titan I very strongly recommend going with the Redarc Tow-Pro Elite item # RED44FR over the Curt Spectrum item # C51170, which does use Wiring Adapter item # C51382 to connect to your 2018 Nissan Titan. The Redarc Tow-Pro item # RED44FR, which you can install in your '18 Titan with Wiring Adapter item # 3050-S, is by far the superior option because it is not only extremely effective and responsive but its manual control knob makes it simple to use; the Tow-Pro can...

This harness will come with the connections to your factory wiring and also the relays required to activate the factory wiring for proper function.

I recommend using the Tekonsha Wiring Adapter for Electric Brake Controllers # 3050-S.

I recommend using the Redarc Tow-Pro Elite Trailer Brake Controller # RED44FR and custom wiring harness # 3050-S. There are many brake controller options for you and I've linked a page to them, but I personally like the function and the clean mount of the Tow-Pro Elite. If you want to be able...

If you don't have wiring harness # 3050-S you will want that. The Mounting Panel for Redarc Tow-Pro Elite Trailer Brake Controller Control Knob # 331-TPSI-007 is a custom fit for some Toyota models.

  • Trailer Hitch and Wiring Harness Recommendation for 2019 Nissan Titan Without Tow Package
    I recommend using the Curt Trailer Hitch Receiver # C13304 for your 2019 Nissan Titan because we have found that the Curt hitches tend to have better welds and a thicker powder coat which means they will last longer than other options. For wiring you just need the wiring kit # N40975 as well as the mounting bracket # 18136. If you check out the attached installation video of the 2017 Nissan Titan you can see that the wiring harness you need is on the passenger side of the vehicle near...

For the 7-way, use part # N40975 which provides both a 4 pole and a 7-way. The connector will plug into the US Car connector located under the rear bumper, and includes the needed relays. You'll also need the # 18136 mounting bracket for the trailer connector. For a brake controller, I'd recommend...
