Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring.

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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring.
Service at etrailer was great & the hitch has worked perfectly.
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.
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!
Trailer towing package has worked great and after one year I have had no issues. Price was great compared to dealer cost.
installation video made it super easy and fast
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 .
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.
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.
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.
Your video was a big help in letting me install this wiring harness for my 2014 Infiniti QX60. And I am very pleased with the purchase and your team.

Excellent best investment easy installation
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.
Very easy setup and installation. I used video's provided by etrailer and YouTube and had no issues. Exact plug and play setup for 2018 Pathfinder
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.
This product was exactly what I needed for adding a hitch and wiring to my 2017 Nissan Pathfinder. The website was super easy to use and the installation video was so helpful. I installed this product myself in less than 30 minutes. Great customer service! Great communication! I will definnitely buy all of my trailer and towing needs from etrailer.com
Perfect fit for my Pathfinder. Having two individuals for the install is recommended, but one person can get the job done. I can rest assured that the receiver will perform!
This wiring harness worked perfectly on my 2020 Nissan Pathfinder SV. Installation was fairly straightforward. The etrailer installation video was extremely well done and helpful.
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.
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
I am very pleased with the customer service that I received from Montrell. He went over my order with me. We talked about what I was using the for. All supplies came to me in a timely manner. I watched the installation video. It made installation very easy. Thanks again for great service.
I’m not a mechanic. Normal DIY guy who prefers woodworking and home improvement. The instructions were simple enough for me to figure out and the harness works perfectly.
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.
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.
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.
Worked great and easy to install following the videos on your site.
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!
