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.

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.


Comments
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.

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

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 .

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.

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.

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!

It works! Can't see how it could be easier. If the instructions are not clear enough, the video on the etrailer site almost does the work for you. Both the hitch and wiring are top-notch quality and I am quite happy.

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.

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.

This is my second time purchasing from etrailer. The orders were accurate and the support via videos and information was excellent. Shipment arrived in far less time than I ever expected. Will not hesitate to return for any future needs, great company!

Package arrived in good condition. Installation was right on from the videos. Only thing was my kit did not come with the self tapping screw for the ground wire but that very minor. Over all very happy with this purchase. This is my second time to purchase from etrailer and will definitely recommend them.

Easy except the black connector. I found it was easier to pry the female part from the wall and connect the two.

Due to health conditions and circumstances beyond my control the light connector unit has set on a shelf in my garage for the past year until this past week. My adult grandsons hooked it for me . It was a complete unit and appears to work well when tested. I do not know how long it will be before I will be able to actually use it.

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.

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.

My items arrived as ordered, and four days early! This company doesn't whine about COVID so they can raise their prices and lower their performance, they do their job and they do it well! Other nice touches - photos of the staff who handled each step of the order, and the visual tracking map. Certainly not necessary, but it shows their desire to stand out - which they do consistently.

Seems like the part took a long time before it was shipped (1 week). Not sure if it was out of inventory or what. Once I received the part it had good instructions and a web video of the installation and the part quality was excellent.
