Quickly and easily install a 7-way, RV-style trailer connector on your vehicle with this custom wiring harness. T-One connector plugs into OEM tow package wiring harness - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-One connector plugs into your vehicle's factory tow package wiring harness, which is located just behind the rear bumper, near 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 7-way 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 7-pole connector itself - to help prevent corrosion.

Wiring worked great with the trailer hitch also ordered from etrailer! I had some trouble getting the wiring hooked up though so I needed to bring it to the dealership. All worked out.
I gave this kit to my mechanic and he informed me the product was thorough, parts identified clearly which made it an easy installation
Hitch fit perfectly, the wiring harnesses instructions are vague but thanks for etrailer you tube was easy.
Complaint is t1 7 way plug does not fit there mounting plate.
To finish in a timely manner purchased a Hopkins plug, could not find a adapter to fit the t1.
The wiring harness I purchased for my 2016 Nissan Pathfinder for my towing hitch was very easy to install per their instructions and connected seamlessly with the wiring harness already on the vehicle. I am very pleased with this product and have referred them to several of my friends. I would definitely buy from them again.
Very happy with my purchase of the 2013 Nissan Pathfinder trailer hitch, 7 pin wiring harness and bracket.The videos really speed up the installation, especially the internal vehicle disassembly and wiring. Everything went to plan with no surprises. The parts are well engineered and good quality. I printed out the 7 pin connector schematic and used a 12 volt test bulb to verify functionality. I didn't break any of the plastic clips or skin my knuckles, which is a first for me. I purchased an inexpensive panel clip tool set, which makes removing the plastic trim a breeze. A screwdriver would work fine, but I needed an excuse to buy some more tools.
I removed the blanking plugs from the external harness connectors before installing the hitch. It's easier to get at them. Don't pry the connectors off the body using a screwdriver. Use a pair of needle nose pliers on the reverse side of the clip to release them from the sheet metal.
Excellent web site and videos make it easy to select the right parts.
Love this company. I ordered on a Sunday at 3pm and it was shipped by george by 8pm. And I got it two days later. Could not ask for better service. And their videos showed step by step instructions. So super easy to do yourself. I had to remove the tow mount, and cut some plastic. But still easy. Thanks y'all. Great prices and service. Will be going here for all my vehicle needs. Next will be the roof rack.
Received my hitch, wiring harness and 7 way receiver adapter within a few days. The video was spot on. Asked Jon with etrailer a couple of questions and he responded almost immediately. Everything went smoothly except two hitch bolts wouldn't go into my Nissan. Used two of four bolts which held my tow harness in place which i removed and fixed the problem. I apparently ordered the wrong 7 way adapter plate so be careful which one you order but fixed the problem by drilling 3 new holes and it worked perfectly. Overall I'm very pleased.
Just installed on my 2013 Pathfinder and I have no complaints. The fitment is spot-on and installed very easy and quick. The exterior harness wasn't too long and was actually the perfect length for the mounting point for the 7- way plug. The only thing missing from this kit is the bracket to mount the 7-way plug. Aside from that this is a complete and comprehensive kit.
Great product. The only thing thing to improve is to mention explicitly that the 7 pin connector mount bracket is not included with recommended wiring package or trailer hitch. Otherwise great product, easy to install and looks great.
This was exactly what we needed. Installation was done at e-trailer and they did a great job.
It was an exact fit and installed easily after watching the install video.
Everything is intact , all parts accounted for. Should do the job nicely . Customer is happy that all the things for her vehicle are here and it’s on the schedule.
Very fast shipping and easy access to finding the right parts
The kit had everthing I needed
As I remember watching a youtube video for locations. The whole job was 123 and looked professional. Again Great Kit...
I ordered DrawTite hitch #76031 along with Tekonsha Wiring #118273 and HM40975, 7 and 4-Pole Trailer Connector Socket for my 2018 Nissan Pathfinder SL. I ordered on a Thursday afternoon and the merchandise arrived the following Monday evening (with free shipping and no tax). The hitch arrived in excellent condition with no scratches or scrapes and was packaged very well. The total for my order was a great price! This also included a tube of dielectric grease and a brush. To get a factory hitch would have required an expensive "Technology Package" at a cost of over $2000 or a dealer install which would have cost over $1000.
I did the install of the hitch myself. It would have been far easier if I had a lift to raise the vehicle off the ground, and a helper to hold the hitch in place and get the 6 frame bolts started. I used an ice chest to prop up one side of the hitch while I got the bolts started on the other side. Watch the videos from etrailer before doing the install. I did have to trim about one-eighth of an inch off the corner of the gasoline vapor recovery box on the left underside of the vehicle to get the hitch into a position so that the holes in the hitch lined up with the weld nuts on the frame. I used a rotary file on the end of my drill to do this. The 2X2 receiver does barely touch the bottom of the rear trim on my Pathfinder but did not require cutting the trim to get it to fit.
The Tekonsha #118273 Factory Wiring was not difficult to install. The etrailer video on how to install this item was not as good as it could have been. The installer says he is going to make the 2 vehicle connections inside the left-rear of the vehicle "by feel," which may be fine for someone who knows what he is doing, but was not helpful to me. I pulled back the trim on the inside left rear to make these 2 connections. You should definitely make ALL of your wiring connections BEFORE installing the hitch itself. If you don't, it will be very difficult to reach the connectors outside the right rear of the vehicle if the hitch is already in place. BE WARNED about this.
The HM40975 connector was very easy to install and by having it you will not need to use an adapter to use a 4-way flat trailer connector. I used 2 stainless steel bolts to fasten the bracket into place instead of the included self-tapping bolts that were in the kit. This item is well worth the small cost.
I am completely satisfied with my purchase from etrailer and will not hesitate to recommend them highly. Both George and Adam at Etrailer were very helpful.
See the picture of the completed install on my 2018 Nissan Pathfinder SL.
Saved more than half what it would have cost me at U-HAUL. Glad I had help and access to a lift.

The service ans support were great. The product fit perfectly.
It's nice to do business with a quality company. I will let all my friends know about eTrailer.
The only thing I can criticize is that wiring harness should have the bracket for hanging on the tow hitch. I had to buy that separately. It's not an expensive piece only a couple bucks.
I received the product in a timely manner and it was ordered just before a holiday weekend as well! Everything was packaged well and all necessary instructions included. I was not a fan of the grade 5 hardware included to mount the hitch but there were enough factory bolts from removing a bracket to make the kit work. The online instructional videos are also great to look at before installing the product. It is self explanatory if you have any mechanical ability but, very helpful for those who dont.
I had zero issues installing the T-one harness into my car and although there isnt a video online for disassembling my particular vehicle. The other videos provided give you an idea as to what is involoved as well as the great instructions that are included with the harness!
I have had a hitch installed by a major chain and will never do that again as this twenty minute install was super easy, engineered well and has a great fit and finish! Thanks e trailer for the great product and one stop shop experience!!

Still doing great after a year of solid use!
Easy to follow and Etrailer provides videos on how to install as well.
I ordered the Draw-Tite Hitch #76031, along with the wiring harness for my 2014 Pathfinder. Julie H. made the ordering process easy. To my surprise, the installation went very smoothly. The video instructions online made the job simple. I have yet to use my new equipment. I look forward to our upcoming camping trip to try it all out.

I am very happy happy with my purchase.
Received parts in just a couple of days and installation was easy and straight forward installation on all tow hitch and electrical for brake controller components. Again etrailer comes thru with what i needed for the best price and parts.

The tekonsha brake controller works perfectly
Great product and very affordable. The installation was quick and easy
The left turn signal and brake light didn't work on install. I still have to tear everything apart again to troubleshoot. Camper at storage. Takes an hour to get to relays behind panels and I just haven't bothered.

Check your vehicles owners manual to see where any fuses or relays are and test them to make sure they are working. If they are working grab a circuit tester like item # PTW2979 and test the connector and wires every foot or so, going into your harness on the vehicle side, after disconnecting it from your trailer. If it turns up okay then test the signals coming out of the harness. If those are correct then your issue lies within the trailer side. Check for corrosion build up which can interfere with signals. If you need to replace the plug you can use item # H20043. If you need to replace wiring you can use item # 16-1-1.

The harness is still working as it did when first installed. Would highly recommend this product.
