Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located just behind the rear bumper, in the center of the vehicle. Once you've plugged in the tow harness, insert 2 of the blue relays and the brown relay into the included jumper harness. This harness then plugs into the port that is located behind the driver's-side trim panel in your rear cargo area. Plug the remaining 2 blue relays directly into the relay box under your hood.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Trailer towing package has worked great and after one year I have had no issues. Price was great compared to dealer cost.

works great with no issues!

2013 Nissan Pathfinder

Great product at a fair price. Excellent packaging. Very easy installation.

Everything was exactly as the included instructions displayed. It took about 90 minutes start to finish with only hand tools. No helper or jack needed.
Although the hitch itself fit the vehicle precisely, I had to remove the towing mount due to it overlapping the frame where the hitch mounts. Not a big deal as the tow truck guy can hook to the new hitch instead.

A note which will likely be frowned upon by eTrailer, if you want to avoid removing the rear threshold, the trim piece, and the cargo compartment, and the huge speaker if installed, there is an alternative.

If you pop off the access grill in the rear side panel, you can carefully cut the nonessential plastic out (using care not to remove the outer area where the grill plugs in) with a heated razor knife, you can easily access the harness plugs.

The only negative was after paying extra for three day shipping, with a limited window to install it, it took FOUR full business days to receive.
Overall, a great experience!



by:

Service at etrailer was great & the hitch has worked perfectly.



by:

It took me more than an hour to install the hitch and wire harness
Watch the video how to install . It very easy to install but you going to need a second set of hand to hold the hitch up .



by:

It was really easy to install and the video showed every step perfectly. I used the zip ties for the plug until I get the mount kit. The only thing is it didn’t come with a self tapping screw.



by:

Watched the installation video and when I installed the wiring harness, it was spot on. Smooth installation. I do control electrical work at a automotive plant and the quality of the parts was equivalent to the parts I use at work. We have high standards on what we use. Great experience.

Instructions were missing a couple of steps, the etrailer video was very helpful. 2020 Pathfinder SV with tow package already had the relays under the hood installed.

When I opened the large hitch box, I looked down and I could see the harness and plastic bag with harness parts sitting on the bottom. It looked like someone just tossed them in. Then I found the harness box taped to the underside of the hitch and the top of the box opened during shipment. No problem. Everything appears good with no missing parts.

The harness worked out well and still is. My son, who is a mechanic, installed the harness and hitch. It took him a few extra minutes to figure the parts out, but mission accomplished.



by:

The Draw-tite Max-frame hitch receiver arrived on time and was installed within 30 minutes. The wiring harness that was purchased with the hitch was just as easy to install. The installation videos were on point and very helpful.

The products have certainly served our needs, and we are very pleased with our purchase.

Excellent best investment easy installation

Don't follow the instructions for the wire harness watch the etrailer video .
The instructions leave out alot of details for installation of the wire harness.

Great



by:

Perfect match to vehicles systems. Installation was fairly easy to perform with most of the work contributed to disassembly and reassembly of vehicle panels to excess wiring harnesses.



by:

I’m very satisfied. I was able to install the following products on my vehicle very quickly and easily.

• Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2"
• T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

Delivery was very quick. The videos on the etrailer.com website were very helpful and all of the parts fit without any issues.
I would have had to spend at least twice as much to have someone install the same thing, and at the time, I couldn’t find anyone in my area willing to do it.

Following the directions you can't mess it up! Worked perfectly following the video!

Purchased wiring harness for a 2015 Pathfinder. Harness was simple to install. Took about 10 minutes to connect. Super fast shipping. Received within two days of purchase. Works perfect.

Perfect. Works great for hauling a trailer or using a bike rack.



by:
2015 Nissan Pathfinder

I installed this wiring kit in my 2015 Pathfinder about a year ago. And, it works perfectly. I use it pulling my boat every weekend.
Part of the installation was a little tricky, but that's entirely due to the way Nissan wired the back of the vehicle. The rear access panel on the driver's side is pretty tight. Apart from that, the installation was easy. And, I found several online videos showing every step in detail.



by:
2015 Infiniti QX60

I had a tough time chasing the weldnut holes in the frame as they were corroded. That took me about 3 hours. Torqueing, oiling, heating, backing out, starting over. eventually got the holes prepped. This was no fault of etrailer, though. Once the 6 holes were prepped, I was able to install the hitch in less than 15 minutes with the help of my son.

The electrical wiring took about 2 hours. Not difficult, just time consuming with having to remove a number of interior body parts. I used the on line videos instead of the written instructions that came with the wiring kit. The video was precise and if you follow every step, you will have no problems. Everything worked perfectly. Doing this myself saved me over $300.



by:

Great direct plug and play. Very thorough instructions. My 15yr old son installed this with very few questions. He did a great job on the install. Definitely recommend this product and any product etrailer has to offer

Shawn B.

Still working like brand new. Highly recommend this product easy install my 11 yr old pretty much installed it with me helping



by:
2015 Nissan Pathfinder

This wiring harness kit is perfect for a diy install job. The part that really makes this kit worth it is the accompanying installation video provided by etrailer.com. I definitely couldn't have installed this myself without the detailed info provided by this video. Once I knew where these parts went on my Pathfinder, and how to get there, it really was a diy job.



by:
2018 Saturn Relay

Easy to install; however, I deviated from the website's video instructions as to the installation of the relays. The video suggests the removal of the rear cargo bin and to then remove a bracket to access the wiring for the relay. The rear bolts holding the bracket in are VERY difficult to access, so I chose to pull back the interior panel at the rear taillight. This method of accessing the wiring harness was much easier than removal of the bracket as shown in the video.

Product works great!



by:
2017 Nissan Pathfinder

Installed a new trailer hitch on my 2017 Pathfinder in about 1.5 hours. Worked great and has enabled me to tow u-hauls or simple stuff like bike racks. Good product.



by:
2016 Nissan Pathfinder

If you follow the video and buy a $5 panel puller it works great. Took a little over an hour to complete.

  • Can I Get The Jumper Harness For 2017 Nissan Pathfinder Separately From The T-One Wiring Harness
    Unfortunately, Tekonsha does not sell the jumper harness separately. You will need to get the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 118670, in order to get this part.

  • My 4-Way Wiring Harness Is Not Getting Any Power On My 2017 Nissan Pathfinder Platinum
    I have a couple of recommendations for you. The first thing I would suggest is to test your 4-way wiring harness where it plugs into your truck wiring with a circuit tester, part # PTW2993, at the connection and not at the 4-way flat. If you are getting power before the wiring harness, your problem is with the wiring harness itself. My next recommendation is to make sure your 4-way flat is connected to a power source. This wiring harness should already be plugged into a jumper AND grounded....

  • Trailer Turn and Brake Lights Not Working with 2018 Nissan Pathfinder
    Your 2018 Nissan Pathfinder does require a couple of blue relays to be installed to fully activate the tow package so that the turn/brake signal lights work on the trailer when connected. The relay harness on your Pathfinder gets plugged into a factory port at the rear of the vehicle behind some paneling on the driver side. I have attached an installation video that you can use for reference where we use the Tekonsha T-One Wiring Harness # 118670, which includes the needed relays. The...

  • Best Trailer Hitch Receiver for 2017 Nissan Pathfinder for Towing and Bike Rack
    The best trailer hitch receiver for your 2017 Nissan Pathfinder is the Curt Trailer Hitch Receiver # C13309. You mentioned you wanted an American product, and this hitch is made in the USA, has a 6,000 lb towing capacity to match your Pathfinder, and has a 2 inch receiver, which means it is highly versatile for towing and accessories like a bike rack compared to a hitch with a 1-1/4 inch receiver. It is also going to be mostly concealed, as you can see by the accompanying photo of the...

  • Trailer Connector Options for 2018 Nissan Pathfinder
    We do indeed have trailer connector harnesses that will work with your 2018 Pathfinder. If you needed a 4-pole trailer connector, use # 118670. For a 7-way trailer connector, use # 118273. Both harness kits include the relays needed to activate the trailer wiring tow package. If you use the 7-way and the trailer has electric brakes, you'll need a brake controller to actuate them. The Tekonsha Primus, part # TK90160 is a reasonably priced proportional controller that would provide reliable,...

  • Trailer Hitch and Towing Accessory Recommendation for 2014 Infiniti QX60
    We do have hitches that will work for your 2014 Infiniti QX60, but the # 76034 you specified is a fit for the Ford Explorer, and wouldn't fit your Infiniti. Not only are the frame members at a different width, but the mounting holes are all different and wouldn't match up. For your QX60, I'd recommend the Curt Class III, part # C13126. This is a mainly concealed installation, which means that the only visible portion of the hitch will be the receiver tube and the safety chain hoops. If...

I have included a link to a video showing an example installation of this hitch for you. For a trailer connector I recommend # 118670.

    The trailer hitch I recommend for your 2018 Nissan Pathfinder is the Curt hitch part # C13309 because it has plenty of towing capacity, is made in the USA, and has a concealed crosstube which means it will be less visible than most hitches.

  • Easy to Install Trailer Wiring Harness Recommendation for a 2014 Nissan Pathfinder
    The Tow Ready trailer wiring harness part # 118670 would be a confirmed fit for your 2014 Nissan Pathfinder. This would be a much easier install than the part # HM11143690 as it does not require accessing the taillight harnesses and then running a wire up to the vehicle battery. I attached an install video for the # 118670 for you to check out as well.

  • Trailer Wiring Harness Recommendation for 2017 Nissan Pathfinder
    For your 2017 Nissan Pathfinder the correct harness you would need for a 4 way would be the part # 118670. If instead you were looking for a 7-way you would want the # 118273. Even if your vehicle does not have the tow package it has the needed wiring for either connector to install.

  • Complete Trailer Towing Setup for 2018 Infiniti QX60
    Congrats on winning the trailer! Even though your teardrop is small and light I still recommend the higher-capacity hitch option from Draw-Tite, part # 76031, since it offers an easier installation than the lower-rated Curt model # C13126. Extra capacity translates into more safety margin, which is always a good thing in towing applications. I linked the written instructions along with a complete install video to show you how the hitch bolts on and the included photo shows the nice clean...

  • Hidden Trailer Hitch Recommendation for 2019 Infiniti QX60
    For your 2019 Infiniti Qx60 the Curt hitch part # C13126 is what you want. Unlike the other hitch for your vehicle it has a concealed crosstube which means you'd only ever see the hitch opening. See picture. For trailer wiring you'd then want the # 118273 for a 7-way or # 118670 for a 4-way. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or...

I have attached an install photo for you. If you will be towing then you will also want to use the T-One Vehicle Wiring Harness part # 118670 for a 4-way or part # 118273 and part # PK12711U for a 7-way. The etrailer...

It has a class IV rating with 2" opening that will be great for towing or hitch mounted accessories. If you will be towing then you'll also need a trailer wiring harness for which I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118670.

  • Upgrading a 2017 Nissan Pathfinder with 4-Way Trailer Connector to Tow a Trailer with Brakes
    You're already off to a great start with the Draw-Tite hitch, part # 76031, and Tekonsha 4-way wiring harness, part # 118670, you already have on your 2017 Nissan Pathfinder. You're going to unplug the 4-way and instead use the replacement 7-way, part # 118267. The jumper harness with the relays that you installed before from the 4-way will stay in place and still be used by the new 7-way. Then you need a brake controller for the trailer's brakes.

  • Trailer Connector Recommendations for 2013 Nissan Pathfinder
    The trailer wiring kit you need will depend on what kind of trailer you're wanting to tow and what kind of trailer connector it has. For a smaller trailer that doesn't have brakes and uses a 4-pole trailer connector, the # 118670 would work great. If your trailer has a 7-way trailer connector I'd recommend the # 118273 which is compatible with vehicles with or without the tow package. If the trailer has brakes, you'll need a brake controller to actuate them. For a simple electric braking...

  • Do Some 2013 Nissan Pathfinders Have Blue Relays for Trailer Wiring Already Installed
    Some Nissan vehicles will have the blue relays already installed. Some will have some but not all. If your 2013 Nissan Pathfinder has them already and the trailer wiring seems to be functioning fine after you installed the # 118670 then you would be ready to tow.

    It is very likely that the reason you aren't getting any power, and the turn signals and brake lights are not working on your 2018 Nissan Pathfinder with the T-One Vehicle Wiring Harness # 118670 is due to a faulty relay. You mentioned the fuse was good but there should be a pair of blue relays that are for the turn signals/brakes in the same box on the driver's side by the headlight.

Both kits include the necessary relays for the tow wiring. The Tow Ready T-One Wiring Harness you referenced, part # 118554, is a correct plug-and-play fit for various model years of the Jeep Liberty and Dodge Nitro.

  • Will a Hitch From a 2015 Nissan Pathfinder Also Fit a 2016 Nissan Pathfinder
    Yes. The 2015 and 2016 Nissan Pathfinders are part of the 4th generation of that model so a hitch like the Curt # C13126 will fit on both years of the Pathfinder. If you need a new trailer wiring harness and relay kit for your 2016 Nissan Pathfinder I recommend using the Tekonsha T-One # 118670, because of the reliability of Tekonsha wiring components. This kit will provide you with a 4 way trailer connector and the required relays to activate your towing package circuits.
