Video Transcript for Tekonsha T-One Vehicle Wiring Harness Installation - 2018 Nissan Frontier

Today on our 2018 Nissan Frontier, we're going to be taking a look at and showing you how to install the Tekonsha T-One vehicle wiring harness with 7-way trailer connector. That's going to be part number 118266. To help us with our installation, we're going to be using the Pollak mounting bracket, part number PK12711U.Here's what our wiring's going to look like once we have it installed. I do want to mention that our kit is not going to come with a mounting bracket, so we will need to pick one of those up so we can secure the connector at the back of the truck. Our wiring's going to give us a 7-way connector, that way we have all the required lights to get down the road safely, like our turn signals, stop lights, tail lights, and our reverse lights.It's also going to give us a 12 volt power source at the back of the 7-way, and the option to use an electronic brake controller if we choose to put one in later.The spring-loaded door along with the rubber gasket on the inside is going to prevent any kind of debris or moisture from getting inside. What I really like about our wiring is the fact that it is going to be a completely plug-and-play installation.

We're not going to have to cut or splice into any wires at all. We're not even going to have to remove our tail lights. We're going to have two connectors underneath the vehicle, and then we'll have a few relays that we'll have to put in place on the inside.So now that we've seen what our wiring looks like and gone over some of the features, let's show you how we got everything hooked up. We went ahead and mounted our 7-way bracket. Now we're going to take our 7-way plug, we'll slide it through, and the holes will line up, and we can take the hardware from the bracket and attach everything up.

Start by taking one of the screws, we'll go through our connector, all the way through the bracket, and then we'll secure it on the back side using a locking nut. We'll repeat that for all four holes, so we can make sure our 7-way is going to be secure.I'll come back and I'm going to take a flathead screwdriver, and while I'm holding the nut on the back of my finger, I'll just tighten it up to where they're nice and snug.If we move underneath, on the side of the frame rail on the driver's side, we're going to have two plugs. We're going to need to take the caps off of each of them. The easiest way to do it without having to take the plug off of the frame, you just take a pair of needle-nose pliers, and we'll come in and we're going to squeeze on that tab, and then we'll pull down, and we can pull the plug out. We'll do the same thing for the other plug as well.With those caps unplugged, we'll grab our wiring harness.

The black plug is going to plug into the black connector on the bottom. Just push it in until it locks into place. And then the gray plug is going to plug into the gray connector. We'll take the other end with our 7-way connector on it and we're going to route it towards the back of our hitch where we have our 7-way plug at.Before I plug my connector in, I'm going to take some dielectric grease and I'm just going to fill up this entire area. Hopefully, that'll prevent any kind of corrosion from building up and moisture getting inside the connector.

If you need some dielectric grease, you can pick it up here at etrailer.com. We'll just line it up and push it til it locks into place. We can tie up any of the excess wires to the back of the hitch here.Now that we have everything connected back here, we're going to move into the cab on the passenger side. On the passenger side, right by the outer door here, we're going to have this kick panel. If we look at the very back, we'll have this plastic fastener that's holding it in place. You should be able to remove this by hand, just turning it to the left to unscrew it. And then we're going to have to remove this lower panel on the side here. If we start on the lower part at the threshold, we should be able to get our hands underneath it. We'll pop all the clips out, so we can remove this piece. And then we'll grab behind this piece and I'll pull this one out as well.Now, behind all those panels, we're going to have several plugs. We should have one that's going to be open, it's going to have several pins on it, and it should match up to the other side of our harness. We'll take our white connector and plug it in, want to make sure it locks into place.On the other end of our harness, we're going to have a few more plugs, and we're going to be plugging some relays into there. We'll have two white plugs, we're going to have two blue relays. These are going to be exactly the same, so we just want to make sure that we plug them in correctly, but it's not going to matter which one we plug into where. We'll plug them in, make sure they lock into place. And then the brown connector, we're going to take our brown relay and plug it in. Again, it only goes on one way, just want to make sure we get it in and locked into place.Now, to help with keeping down the noise and our relays rattling around when they're back here, they are going to provide us with some of this foam insulation. What we'll do is we'll take off the backing, and we're going to wrap our relays so that even if they do bounce around a little bit and move, hopefully this will cut down some of that noise and we won't have that plastic on plastic contact noise. So we'll do that for each one of our relays. Then you can tuck the relays and the rest of your harness back into this little cubby here, and we can put all our panels back in place.So I went ahead and plugged in my tester to make sure that all the functions are working properly on our wiring. We can see that the tail light function is working, as well as the left turn signal, the right turn signal, our brakes, and even the reverse turn signal. All we have left to do now is hook up to our trailer and hit the road.That'll finish up your look at the Tekonsha T-One vehicle wiring harness with 7-way trailer connector on our 2018 Nissan Frontier.

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

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 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 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

Not sure whether it is my truck or the harness but the brake lights and aux power where crossed. Took it to a local shop $100 later all is good. Harness is nice. Again I don't now if it was my truck or the harness. If you have a 4 way that works properly your probably fine 599443

This was very easy to install. Install video was a big help. I installed this 1 year ago and have not had a problem with it. Took about 30-45 minutes to fully install, and I took my time not to break any of the trim pieces. 647636

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

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

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

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

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.

The harness was exactly as represented and plugged and played just like I expected. I was pleasantly surprised to find that the relays were actually included on my truck's original wiring so I only needed to add the bumper connector, and sure enough, my Xterra has the same wiring error as others reported affecting the trailer braking, but a simple wire swap took care of it. 767822

  • 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...

The T-One harness comes with everything you will need to install a 7-way trailer connector on your Pathfinder. If you do not have a 7-way mounting bracket on your trailer hitch than you can use part # 18140 and part # PK12711U to...

  • Mounting Bracket to Install 7-way Trailer Wiring Harness # 118266
    I linked a video of when we install the # 118266 wiring harness on a 2008 Nissan Xterra and we used Mounting Bracket # PK12711U along with the No-Drill Bracket # C57202.

  • Troubleshooting No Power to Brake Controller 2005 Nissan Xterra After 7-Way and Controller Install
    If the controller isn't powering up that would be why the trailer brakes aren't activating. Since you installed the 7-way kit with the relays and then most likely used the # 3050-P (or one similar) to install the brake controller it would seem very likely that you are missing a relay for the brake controller. The easiest way to find all the fuse and relay locations is to use the vehicle owners manual. In the index you will look up fuses and then go to the appropriate pages and it will...

  • Mounting Bracket for 7-Way Trailer Connector Installed on a 2013 Nissan Frontier
    Since the 7-Way part of wiring harness # 118266 for your 2013 Nissan Frontier can be surface mounted, a mounting bracket isn't mentioned but is listed on the right hand side of the page under Related Items. The recommended bracket listed is # PK12711U. To use this without attaching it directly to the truck you can use short bracket # 18140 or long bracket # C57202. Curt also has a neat bracket that attaches around the receiver, # C58000. I have included some video links on these...

  • Installation of T-One Trailer Wiring Harness in 2017 Nissan Frontier
    For your 2017 Nissan Frontier, I recommend the Tekonsha T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118266. This installation requires a connection at the rear of the truck as well as a connection inside the cab on the passenger's side kick panel, which requires removing a side floor sill but nothing on the door itself. The installation is the same if your decide to install the # 118525 which will give you the 4-way trailer connection. The front kick panel connection...

  • Bracket Recommendation For Mounting 7-Way to Draw Tite Hitch 75282
    You never want to drill into a trailer hitch to mount a 7-way, but the # 75282 you installed does come with a trailer wiring mounting bracket. You could use the part # PK12711U to attach the 7-way of the # 118266 to that mounting bracket and you'd be set.

  • Adding a 7-Way Trailer Connector to a 2011 Nissan Pathfinder with Factory 4-Way
    Trailer wiring harness # 118266 will work to upgrade your 2011 Nissan Pathfinder from a factory 4-Way to a 7-Way trailer connector. The relays you are looking at sound like they are not in the same location as the relays that are included with the harness. The jumper harness with the 3 relays will install behind the front passenger side kick panel. They do not install under the hood. The jumper harness and relays are needed to make the 7-Way connector fully functional. It sounds like...

  • Installing 7-Way Harness On 2012 Nissan Xterra
    I see from your recent order that you purchased the Tekonsha Primus IQ brake controller, part # TK90160 and the wiring harness adapter, part # 3050-P. You can simply plug one end of the adapter into the back of the brake controller and the other end into the port located under your dash near the emergency brake pedal and will be taped to another wiring harness. The # 118266 you purchased will plug into the two connectors on the driver side frame rail near the back of the vehicle. You...

  • Will TowReady Nissan 7-Way Tow Package Wiring Harness # 118266 Fit 2014 Nissan Xterra
    The confirmed wiring harness fit for your vehicle is the Curt # C55441 which is a 4-pole harness for the Xterra with the factory-installed 4-pole. If you want to convert the lighting signals from the 4-pole to a 7-way blade style connector you can use the plug-in adapter # 37185 from Hopkins. This has a 4-pole female plug to mate with the 4-pole on the harness and will transmit the lighting signals through the 7-way RV-style socket. Please note that only lighting signals will pass...

  • Trailer Tail Lights Not Working when Connected to a 2012 Nissan Frontier
    On your 2012 Nissan Frontier I do believe there are tow package relays located under the hood. I have heard of this before on a similar truck. If not then it is entirely possible that adding in that harness with the relays behind the kick panel will solve the problem if it is indeed the proper location that you are seeing. There is also another caveat that affects some Nissan vehicles and that is that the connectors where the 7-Way part of # 118266 plugs in are not all wired the same....

  • 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...

  • Missing Relays for Trailer Turn Signals on 2012 Nissan Frontier
    It sounds as if you might be missing two of the relays. The relays are available individually as part # 38666-1. The blue relays control the turn signals, and it sounds like that's what you're missing. I've linked you to a photo showing where the relays are usually located, and also to a video showing the same thing.

  • Infamous Black/Blue Wiring Mixup On The 2005-2013 Nissan Xterras
    Chances are that if the brake controller is reading the trailer while connected, then it is not a blue/black wire mixup. To test this you will need to use a circuit tester like part # 40376 and probe the 5-o'clock position on the rear of the 7-way. If the power is constantly hot, the wires are switched. If the 5-o'clock position is only hot while the manual override is activated, the wires are not switched. If the wires are switched, you have two options. The first option would be to...

  • Remove Plugs on Factory Wiring Harness to Install Trailer Wiring on a 2013 Nissan Frontier
    I think the video you are referring to is the one I have linked here. The release is right where our installer is pushing on the connector with the screwdriver. You have to push in and pull down at the same time. The part you will be pushing in and down on is the cap so you are not likely to break the connector. Road grime could have gummed up the plug and connector a little so it may need to be cleaned with a few squirts of WD40 and then wiped off. You just don't want to get any WD40...
