Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118266 Review

Today we're going to be taking a look at Part Number 118266. This is the tow-ready vehicle wiring harness. It's going to come with your relays and a 7-way trailer connector. This product fits certain years and models of the Suzuki Equator, Nissan Frontier, Nissan Pathfinder and the Nissan inaudible 00:00:18. The wiring harness is for vehicles without a factory trailer connector. It's going to install very quickly and easily.

You don't have to worry about cutting or splicing any wires during the installation. All you have to do is locate the connection points along the frame rail, plug in the connector, this portion right here, and then this portion right here's going to plug into the back of your new 7-way. It just snaps together like that, very easy to do. This harness right here is going to be the 12-pin connector. This is going to be your relays. They include this which is necessary for a complete installation and to get everything functioning the way it's intended to.

This unit is going to add a 7-way trailer connector to your vehicle. That's going to send power to your trailer. It's going to connect directly to the standard OEM connector which, again, the instructions are going to be included. Those are going to walk you through the installation process step by step and show you exactly where all the connectors are in order to connect this but, again, it does install very quickly and easily. The lid right here is a spring-loaded design for the 7-way connector. It's also going to have the nice gasket right here.

It's going to really limit, if not eliminate, any water from getting into the connector when the lid is in the closed position. It's got the inaudible 00:01:33 on here. This is designed and we also recommend to use a mounting bracket to get this mounted at the rear of the vehicle. That's just going to help you to connect or secure. The custom-fit harness is going to plug into your factory toe package, wiring harness, which is going to be located beneath the rear of your vehicle along the driver's side frame rail.

Again, the instructions are going to point that out really well. Before connecting the actual 7-way itself, you want to plug in the included harness with the relays. These, again, are going to plug into the 12-pin connector at the front of your vehicle. It's got the relay caps included in the little bag. Also in the bag are going to be the zip ties and some foam tape. Now you can use the included cable ties and the foam tape to secure the harness to prevent damage or rattling. Once your installation is complete, the 7-way connector will be stowed beneath the vehicle near the trailer hitch. Again, we do recommend using a mounting bracket. The mounting bracket's going to be sold separately but we do carry those here at etrailer.com. Again, that's just going to help keep the connector secure. It's also recommended that you use a small amount of grease on all electrical connections like the plug on your vehicle and the 7-pull connector itself. That's just going to help prevent any type of corrosion to the connection ports but everything that's needed for a complete installation is included. That's going to do it for today's review of Part Number 118266. This is the tow-ready vehicle wiring harness with relays and the 7-way trailer connector. .

Ordered a Class III hitch for 2006 Xterra with wiring. Seamless transaction fast shipping and perfect fit straight out of the box. One of the easiest transactions I have had. I highly recommend etrailer.com to my friends and those who want professional, fast service. 356180

This wiring harness for my 2011 Nissan Frontier (118266, comes with the relays for trucks that are not haul-ready from the factory) is just as advertised. The videos were the most helpful! Please watch them. It took me about 45 minutes to connect the relays inside the cab behind the kick panel on the passenger side, plus the harness at the rear of the vehicle. It took another 45 minutes to install the bracket for the 7-way plug, but that was only because I broke 2 drill bits trying to drill through my bumper. My bad! I tested the installation by hooking up to a trailer before closing everything up, and it all worked perfectly. Just as advertised. 474566


Comments

It turns out that the wires in the harnessing were reversed the trailer lights wouldn’t work. A simple reversing if the wires fixed the problem. Good product, as I had previously reported.

Everything plugged in and worked great. Install was easy and fast. I had a few issues with my install and use and etrailer support team was quick to respond to my calls and requests. My only concern is with the trailer brakes lock up issue that's been brought up several times in the comments and reviews sections. I ran into the same issue and wasn't exactly sure on how to fix this just from reading the comments and reviews. I reached out to etrailer to seek details on resolving this issue, turns out etrailer has detailed instruction on how to fix this problem. It would have been nice if this self-help link is presented/available on the product page. http://www.etrailer.com/faq-tb-14-02-Nissan-Suzuki-OEM-Wiring-Harness.aspx 141469

Everything connected/ plugged in as it should but I as other's saw the brakes lock up. Now I cannot use and do even have trailer brake lights 563723


Comments

The problem is that Nissan miswired the wiring connectors under some Frontier, Titan and Pathfinder models so that the 12-volt accessory feed is swapped with the output circuit for the trailer brake controller. The easiest fix is to cut the blue and the black wires in the harness feeding the trailer connector and swapping them. You could swap the wires on the trailer, but youd need to swap them back before towing that trailer with another vehicle. Youd also need to swap the wires on any other trailer you tow with that vehicle, so its just easier to do it on the vehicle side of things and have done with it.

Everything plugged in, simple install. Only issue was the two wire connector at rear of truck had the black/blue wires reversed in connector. Brakes were on all the time. Did not know how to remove the small metal connectors so just cut black and blue wire and reversed them, all good now. The connectors and relays behind kick panel all went together perfect. Also ordered POD control at same time, all plug and play, works great. Except for the time to figure out problem with the black/blue wire connector, it would be 5 star. 418138

The brake contols, wiring harness, relays are all working fine after the first year. Just had the camper out this week and no problems at all. Nice installation and the videos are most helpful. Thanks

It is always a pleasure doing business with etrailer.com, the communication of order status is great and their shipping is always fast. The wiring harness I purchased for my 2017 Nissan Frontier was extremely easy to install. It did not come with a bracket to mount the 7-way plug to the receiver hitch, but that was not my intended mounting location. The instructions and pictures weren't super clear, but I was able to make sense of them once I pulled the kick panel where the relays are installed. 367400

Ordered this for my 06MY Nissan Xterra. Installation was a breeze, just plug and play. Did find after installation that the 12V feed and the brake controller line at the 7-way plug were reversed after some troubleshooting of an inop brake controller. Not sure if it was a Nissan OEM wiring problem or wiring problem with the product I received. Never-the-less, cut the plug off and put it back on the correct direction. Now everything works at it should. 93080


Comments

I have the same issue with 2005 Xterra. I installed 7 pin harness, all travel trailer lights work but brakes lock up when connected to truck. So I need to switch black and blue wires on vehicle harness connector for it to work. This issue needs to be corrected before e-trailer sells this product. I did not buy this harness so I could make modifications on it.

Most Nissans are wired such that the connector will work properly out of the box. For whatever reason, Nissan wired some with these two circuits flipped, and we have not been able to determine and method or pattern as to which are wired differently. We are working with Tow Ready to find a solution that would not require the user testing the vehicle beforehand.

To date this product has worked flawlessly. Thank you for the follow-up. I will actually be contacting etrailer in the near future for the same type of system for a 13 Ford Explorer!

I had the same problem with my 2011 Xterra my guess is the Harness may have been manufactured improperly. The 7-way connector from the trailer worked perfectly on a 2013 Jeep Grand Cherokee and a 2005 Toyota 4-Runner. but with my Xterra, the 12V black cable seemed to feed the brake controller because my brakes locked up whenever the trailer was connected and the 12V power blade never saw power. The solution I came to was the same one you did but now nobody can tow the trailer except you! I wish someone would fix this issue.

Okay, so I've finally had a day off to fully install the kit in my 2013 Pro-4X Xterra. If you're looking to do the same and are wondering if it has everything you need, don't worry, it does. I didn't time myself during install but I know it took me less than 20 minutes, you don't even have to remove the spare tire to hook up the wiring in the rear. Literally plug and play. It took me a lot more time to figure out where to install the connector. Nissan went out of their way to make this an easy install if you don't have a factory towing package, this kit is worth it. Buy it, use it. 391865

First time out I noticed my break controller was reporting "No Trailer Connected". I then attempted to move the trailer and discovered the breaks were locked. I unplugged the 7-pin trailer connector and borrowed a tester from the trailer dealer which showed the break pin and the battery pins (Black and Blue Wires) were swapped in the connector. I pulled the trailer home without breaks and verified the incorrect wiring with a second tester then swapped the two wires in the connector to resolve the problem. Later that night I looked on the internet and found where others have had the same problem with this harness. It appears the manufacturer has a quality testing issue ?? After repair the harness works as expected and is holding up well to use. NOTE: This is the only issue I have ever had with anything I have purchased from etrailer and will continue to use them in the future. HOWEVER, I suggest you test a new wiring harness BEFORE trying to use it...like I should have! (etrailer part number TR20117) 460641

This #118266 7-Way connector harness kit contains everything needed to install basic trailer light wiring on ALL 2015 Xterras, regardless of trim level. The vehicles are completely factory prewired for a simple plug-in installation as described below (other recent model years are most likely also prewired, just check out my photos of the three connectors and see if they are on your vehicle. If you do indeed have the three connectors, the wiring harness plugs into the two factory installed connectors located on the frame, to the left of the spare tire area (one contains the wiring for the lights, the 2 conductor connector carries the +12v charge line and the brake control wire). The relay cable & relays are installed behind the plastic panel on the right side of the front passenger footwell. The trickiest part is removing that panel, along with the plastic doorsill trim to the right of the seat without damaging them. Be very careful not to break the plastic tabs and grabbers that hold both panels in place. This harness kit does not contain a mounting bracket for the 7-way connector. I recommend the #TM76474 bracket, necessary to mount the 7-way connector to your bumper. If you do need to control electric brakes on your trailer(s), consider the additional two items, below. If you choose something other than a Tekonsha controller, you will need the short wiring pigtail that is compatible with that brand, instead of the #3050P. #90195 Tekonsha Prodigy P3 brake controller. An excellent, top performing unit. Other lower priced Tekonsha controllers may meet your needs. #3050P Wiring pigtail. Connects Tekonsha brake controllers to the factory installed connector (see photo) under the dash, above the right side of the driver footwell. If you use a different brand of brake controller, pick out the appropriate pigtail to match it. NOTE: There are apparently two major wiring standards associated with 7-way connections. One of them has the brake control line swapped with the +12v charge line. Make sure to check your trailer plug and wiring before hooking up to your vehicle. You may need to cut and cross the two lines leading to the vehicle’s 7-way connector. If you need to occasionally swap between the two wiring standards, install insulated male & female crimp-style connectors in the lines. Use heat shrinkable tubing over the connections to make them more resistant to the weather. For a more permanent, reliable connection, solder them instead of using the crimp connectors and apply shrink tubing over the joints. 233614

Product is supposed to be a direct fit for Nissan Frontier install. Unfortunately, this was not the case as the blue and black wires are reversed as reported by so many others on this site and other sites (fortunately, I knew to check before hooking up a trailer) . These wires are for constant power and the trailer brakes. Fortunately, there was a video posted on etrailer on how to reverse the pins on the wiring harness that connects the vehicle wiring with the 7 pin connector at the rear of the vehicle. The video showed how to reverse the pins in the 2 pin connector that attaches to the vehicle wiring - the 2 pin connector contains only the blue and black wires. Not too difficult but definitely takes some time due to the process of installing everything on the vehicle, testing, taking parts back off the vehicle, disassemble/reassemble the wiring connector, reinstall on the vehicle and retest. 3 starts because this is supposed to be plug and play - not sure if this is a Nissan issue or the wiring manufacturers issue but I would have preferred to simply plug it in and be done. Also, I purchased the Draw Tite (Item 18138) mounting bracket and it did not work with this harness - the holes did not match up and would have required drilling all new holes. 522505

I have a 2005 Xterra just purchased. It did not come with the towing package, but before I bought it I found out that everything was there and pretty much plug and play with the right setup. i hunted down a lot of options, including from the trailer rental place for about 250 but was unsure what I would end up with as far as the electrical harness. After a few searches I got a hit from etrailer who advertised two hitches, Curt and one other(so you know which one I picked). I watched all the installation videos, including the add on's. I bought the whole package. Hitch, harness, ( 7 point RV and Marine ready, 7 to 4 adapter for my dump trailer. I also bought the universal bracket to hook up the 7 point adapter. The hitch did not fit my car. It hit the bumper before it would line up with the bolt holes to secure it ,to the holes it was designed to secure it. I had to use a jack to line up the holes, but at the end I got it to fit. I expected to have to modify the bracket, (maybe I will send it to them.) . The hitch actually really did fit, I just had to tweek it a little. Bottom line, I will order again. The product is very high quality, and looks killer on my new vehicle. They have many accessories. Make Nissans Great Again!! Pic coming soon! 656224

I bought this as a replacement to the same item that was previously purchased. The original one only last one year as it did not have an adequate seal for the outside connector and the inner terminals corroded away. The new one was better designed and seems to be holding up OK so far. Otherwise, the wiring harness went together OK and worked fine. 655820

I ordered a receiver, wiring and brake controller for my new Nissan Frontier. Christopher was great to deal with and he handled making sure my order was complete and correct. He answered all my questions. The items arrived promptly and I began the install. There were two issues - not unusual, and in both instances a call to etrailer resulted in friendly, knowledgeable folks giving me fast, correct advice/fixes/email articles that made the install a snap. I've forgotten the first women's name (sorry!) Molly handled the second issue and within minutes had the answer to why my trailer brakes were locking. She sent me an article detailing how some of the wiring from Nissan was installed backward, how to diagnose this was my issue and how to correct it. That made short work of that issue. Accept that those of us who do these installs only a couple of times in our life will have questions/issues and buy from the folks who are going to provide the experience and help to make the project quick and enjoyable. I wouldn't buy anywhere else. 654085

These wiring components work perfectly. They were easy to install with the instructions. Anybody can do this. I got the 7-pole connector in this package and also bought a 7-pole to 4-pole adapter with a test light so I could make sure that the connections were working. I also bought the Polak PK12711Y bracket to put on my trailer hitch. I tried the standard bracket from Walmart but they did not match the hole pattern on the 7-pole connector. Carol C recommended the Polak bracket and the hole pattern matched perfectly. I can now pull my trailer. I will return to etrailer for any of my trailer or other vehicle part needs. Thanks you etrailer. 607765

Bought for a 2018 Nissan Frontier. I had already watched the installation videos by etrailer, so the install was quick and easy. The rear wires and plug were plenty long for proper positioning. There is no bracket for the plug. The inexpensive PK12711U bracket worked fine. The wires and relays that go behind the passenger kick panel were also easy to install. All the trailer lights worked perfect the first time! Very satisfied. 586274

Do you have a question about this Custom Fit Vehicle Wiring?


  • Troubleshooting 7-Way Trailer Connection Wiring on 2017 Nissan Frontier
  • In your 2017 Nissan Frontier, the Curt brake controller should be installed using the custom wiring adapter # C51382. This should work correctly to give you the proper wiring within your cab. Then you will use the Curt # C56226 or the Tekonsha # 118266 to get the correct 7-way. If you have done this even using the previous relays, check your trailer connection for functions using the attached photo and a circuit tester like # PTW2993. It sounds like the trailer may be mis-wired...

  • How to Determine if 2011 Nissan Frontier Has Tow Package for Brake Controller Install
  • Look at the rear of your 2011 Nissan Frontier. If you see a round trailer connector like what you see in the attached picture then you have the tow package. That means that you only need the part # 3050-P to install the Prodigy P3 part # 90195. If you do not have the tow package you will also need to install the part # 118266 to give you the 7-way.

  • Recommended Wiring Harness for 2018 Nissan Frontier without Factory Tow Package
  • For your 2018 Nissan Frontier, the trailer wiring harness I recommend is the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. 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've attached a video of the install on a 2017 model to assist. This is an easy connection to the factory harness located behind the driver's side rear bumper and passenger side kick panel inside...

  • Trailer Hitch Recommendation for 2018 Nissan Frontier
  • For your 2018 Nissan Frontier the Draw Tite hitch part # 75282 is the hitch I would recommend because it has the best towing capacities, installs very easily and has the best price. The towing capacities are 5,000 lb trailer weight and 750 lbs tongue weight capacity. For trailer wiring the T-One part # 118266 is the correct trailer wiring kit to give you a 7-way that's fully functional. I attached an install video for this kit for you to check out as well. If you wanted to do some...

  • Recommended 7-Way and Brake Controller for a 2019 Nissan Frontier
  • The wiring that I recommend installing on your 2019 Nissan Frontier so that you have a fully functioning 7-Way is the Tekonsha T-One # 118266 because it is the most reliable option available. This comes with the wiring and relays needed for the installation but you may be interested in the mounting brackets # PK12711U and # C57202 as well to easily mount the 7-Way. If you don't already have a brake controller then I recommend going with the Curt Spectrum # C51170 because it is a proportional...

  • 2017 Nissan Frontier 7-Way Trailer Wiring Connector Recommendation
  • For your 2017 Nissan Frontier we do have a 7-way trailer harness kit that would work well. It's part number # 118266 and comes with everything needed to install a 7-way. I attached an install video for this for you to check out as well.

  • Hitch and 4-Pole/7-Way Wiring Kit for 2016 Nissan Frontier Pro4x
  • Curt 2-inch Class III hitch # 13241 is a confirmed fit on your 2016 Nissan Frontier Pro4x and installs easily as shown in the linked video. Written instructions are linked too and these tell you the tools needed and provide detailed information on bolting this on to your truck. To have wiring with both 4-pole and 7-way connectors you can use kit # 118266 for the relays and harness and simply substitute connector # HM40975 for the 7-way-only that is included in the relay kit. This includes...

  • Recommended Components To Create A Tow Package On A 2015 Nissan Frontier Pro 4x
  • For your 2015 Nissan Frontier Pro 4x, I have looked through your list to put a tow package on your truck and it is solid, but I have a couple recommendations based on preference. The Tekonsha Prodigy P3 # 90195 is a great choice and a personal favorite. It will connect with the wiring harness # 3050-P to an already factory wiring harness. That factory wiring harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake...

  • Trailer Brake Controller & Wiring Adapter for 2014 Nissan Frontier
  • To add a trailer brake controller and the appropriate wiring adapter to your 2014 Nissan Frontier you will need the brake controller itself, such as the Power Trac # 39523 along with the wiring adapter # 3050-P. If you have a 7-way no other parts are needed, but if you do not you will also need 7-way/relay kit # 118266. You can refer to the linked video for illustration of the controller install process. The Power Trac is a good value in a time-delayed type controller but most folks...

  • Recommended Trailer Towing Kit for a 2005 Nissan Xterra
  • I do have everything you'll need to tow a trailer with your 2005 Nissan Xterra (trailer hitch, wiring harness, ball mount/hitch ball) but we currently do not have an all inclusive kit. For a trailer hitch confirmed to fit your vehicle, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver part # 75291 which is a Class III hitch with a 2" receiver tube opening. As you can see in the installation video I have attached for you, the hitch is very simple to install. Then for a trailer...

  • Recommended Wiring Harness for 2016 Nissan Frontier Without Tow Package
  • For your 2016 Nissan Frontier without a tow package, I recommend the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. This will allow you to easily connect to your factory wiring and have a 7-way. If you only want the 4-way flat since you are using a small trailer, you can alternatively use the # 118525. Many with even small trailers prefer the 7-way but you can use an adapter like # 47345 or a 7-way with integrated 4-way flat like # HM40950. For the trailer hitch,...

  • Trailer Running Lights Relay Location on 2013 Nissan Frontier
  • Trailer running lights not working with certain Nissan vehicles is a common problem with an easy fix. There is a relay for the trailer running light circuit that is located in the fuse box (in the cab). If that relay is missing or no longer functions then it can be replaced with # 38666-1. The relay of the running light circuit on your 2013 Nissan Frontier is in the relay harness behind the passenger floor board kick panel. If you check out the install video I attached the first...

  • Recommended 7-Way Trailer Wiring Harness for 2006 Nissan Xterra
  • The Hopkins Plug-In Simple Wiring Harness # HM43575 referenced in your question is confirmed to fit your 2006 Nissan Xterra, but this will provide you with a 4-Way flat connector and not a 7-Way. In order to install a fully functional 7-Way connector on your vehicle, I instead recommend the Tekonsha T-One Vehicle Wiring Harness # 118266. This custom-fit harness will install by plugging directly into existing ports located under the vehicle, on the driver's side of your Nissan Xterra....

  • How to Add 4-Way and 7-Way Trailer Connectors on a 2015 Nissan Frontier PRO-4X
  • All of the trailer wiring harnesses that are custom designed to fit your 2015 Nissan Frontier are either a 4-way or a 7-way connector. However, if you install a 7-way harness like part # 118266 and replace the final connector with part # HM40920 you'll have exactly what you're trying to accomplish. Part # HM40920 has both a 4- and 7-way and plugs into the same port that the # 118266 wiring uses. If your adventure trailer has electric brakes then you also need a brake controller. I...

  • Upgrading 2017 Nissan Frontier from 4-Way # 118525 to 7-Way
  • On your 2017 Nissan Frontier, since you already have installed the 4-way with the relays # 118525, you will not need to install other relays to upgrade using the # 118266 to the 7-way trailer connector. Your tow package wiring will already be active. You could simply use the wiring connector # 118267.

  • Relay Harness Needed for 2019 Nissan Frontier
  • I do have a solution for you, but unfortunately nobody currently (as of January 2019) sells just the harness for the relays out of the T-One Kit # 118266 that you referenced. Since you already have the 7-Way wiring and connector the next best thing would be to get the Curt T-Connector # C56225 and install that relay harness which is essentially the same thing. This is just at a lower price point because it is for a 4-Way which is less complicated than the 7-Way wiring harness. I have...

  • Trailer Wiring Harness and Mounting Brackets for a 2016 Nissan Frontier
  • We do have a variety of trailer connectors and mounting brackets that you can use on your 2016 Nissan Frontier. If you need a 4-Way Flat connector then the Hopkins # HM43575 will work if you have the tow package. If you don't have the tow package then I recommend the T-One # 118525. You can mount either of these using the Tow Ready # 18144 with a no-drill bracket like part # 18140. For a 7-Way without the tow package use the T-One # 118266 with the mounting bracket # PK12711U and...

  • Recommended Trailer Wiring Harness for 2005 Nissan Xterra
  • We do have a nice selection of trailer wiring harnesses available that are confirmed to fit your 2005 Nissan Xterra that doesn't have the factory tow package or connector. Both the 4-Way and 7-Way options will be pretty simple, plug-and-play type installations, so your best bet is to simply choose the connector that matches what you have on your trailer. If your trailer just has a 4-Way connector, then I recommend the Curt T-Connector Vehicle Wiring Harness # C56225. If the trailer...
