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.

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.
Comments
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

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.

2013 Nissan Pathfinder
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.
by: Sergey05/11/2019
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.

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.

Well designed for my vehicle, installation went smoothly. Appreciate the how-to videos.
by: Henry B09/17/2021
Everything with this wiring fit perfectly. After watching the video install it was a breeze finding the fasteners to remove the access areas. It has been a year since install and has worked without any issues. The only extra I needed was the bracket to the hitch for the female 7 pin plug. The one I ordered from e-trailer did the job and looks professional. Thank you e-trailer on another great product.

2019 Nissan Pathfinder
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.

2018 Nissan Pathfinder
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.

2013 Nissan Pathfinder
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.

Directions were very thorough; I did not have to call for tech support. We have taken our travel trailer out several times and wiring has worked as expected. Price was very reasonable compared to dealer. I buy all my trailer/towing needed products from etrailer.

Everything worked perfect! Order was received complete and no issues with installing. Thank you for providing a very satisfactory product. Very clear and multiple resources for installation, super satisfied with your product. Thanks again!
by: 05/05/2021
Perfect part for the job! Good installation video to assist. Everything needed for the job! All was just plugging and play as the Pathfinder was pre-wired. I included the harness pictures as they were behind a panel in the hatch and mounted to the wall. I couldn't find a way to expose them and the video skipped that part. There was just enough room to get 1 hand in and for me to blindly plug them in behind the wall. The color on the plug proves it's a tight space and the vehicle harness is fixed to the wall. Used the picture to align and blindly plug in and it worked out.
Overall a good experience!

- 7-Way Trailer Wiring Connector Recommendation for a 2015 Nissan PathfinderSounds like you have found the connector on your 2015 Nissan Pathfinder that a 7-way would plug into. What you would need to install the 7-way is the Tow Ready Kit part # 118273 which is a confirmed fit for your vehicle and comes with everything needed to install a 7-way.
view full answer... - Does 7-Way Trailer Wiring Harness part # 118273 fit 2015 Nissan Pathfinder without Tow PackageThe trailer wiring harness part # 118273 that you referenced is a fit for your 2015 Nissan Pathfinder and would work well to provide you a 7-way trailer connector. There was some confusion at one point as to whether or not this would fit if the vehicle didn't have the tow package but we now know that it will.
view full answer... - Installing 7-Way Kit # 118273 in 2015 Nissan Pathfinder with Factory 4-WayFor your 2015 Nissan Pathfinder with a factory 4-way your best option is going to approach it like it's a new install and use all of the components that come with the # 118273. This may require removing harnesses already installed that are basically the same but easiest way to prevent trying to track down problems (if they arise) will be to do the complete install. Most likely a few of the relays will already be in place too. I attached an install video for this kit for you to check out...
view full answer... - Trailer Wiring Recommendation for 2016 Nissan PathfinderI really wish I could recommend you the ability to tow a heavier trailer than what your current trailer hitch says and it is true that Draw Tite and Hidden Hitch are actually the same hitches but if your hitch is older I can't safely say it's fine to tow heavier. Also, you should really check the capacity of your Pathfinder in the owners manual everything I am seeing is a max of 5k. For trailer wiring though you would want the part # 118273.
view full answer... - Recommended Trailer Wiring Harness for 2014 Nissan PathfinderIf your 2014 Nissan Pathfinder has the factory tow package then the correct 7-way wiring harness kit is # 118273. This kit includes the required relays and connects to the vehicle behind the rear bumper. If you want a 4-pole harness or do not have a factory 7-way then the correct kit is # 118670 which also includes the relays and shares the same connection point under the bumper. Some Pathfinders without the tow package may not have the relay box in the back and so this might need to be...
view full answer... - Trailer Wiring Recommendation for 2018 Nissan PathfinderDepending on what type of trailer connector you need you'd want the Tekonsha part # 118670 if you want a 4-way or if you need a 7-way you'd want the part # 118273. Both are custom fit kits that don't require any hardwiring. The Tekonsha brand of trailer wiring is our most reliable option we have. I attached install videos for both kits for you to check out as well.
view full answer... - Recommended Trailer Wiring Harness for 2018 Nissan PathfinderIf you need a 7-Way connector harness (if your trailer is equipped with a 7-Way) I recommend the Tekonsha T-One Wiring Harness # 118273 and for a 4-Way harness (if your trailer has a 4-Way connector) I recommend the Tekonsha # 118670. These are both custom harnesses that will install by simply plugging into the factory ports under the vehicle on the passenger side (see attached image) and inserting the included relays if needed. When available I always recommend Tekonsha branded harnesses...

- Trailer Wiring Harness Recommendation for 2017 Nissan PathfinderFor 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.
view full answer... - Trailer Wiring Harness For a 2016 Infiniti QX60 That Attaches Under Passenger Side BumperWe do have the wring harness that you are looking for but the manufacturer does not offer this separately from the kit. Therefore, you can use the T-One Vehicle Wiring Harness part # 118670 for 4-way trailer connectors or part # 118273 for 7-way trailer connectors and then just hold onto the others parts you are not using. This option would still be loads more cost effective than getting just the harness from your dealer which is your only other option.
view full answer... - 7-Way or 4-Way Trailer Wiring Recommendation for 2014 Nissan PathfinderThe style of trailer wiring you need will be based on the trailer you plan to tow. If it has a 4-way you'd need a 4-way harness part # 118670, or if it has a 7-way you'd need the part # 118273. In most cases if the trailer is smaller and doesn't have brakes what you'd need is a 4-way. Or if the trailer is larger and with brakes you'd need a 7-way. I attached an install video for the 7-way on a 2014 Nissan Pathfinder just like yours.
view full answer... - Trailer Wiring Recommendation for 2018 Nissan PathfinderFor your 2018 Nissan Pathfinder the correct 4-way trailer wiring kit is the part # 118670. If you needed a 7-way instead it would be the part # 118273. The other harness you mentioned is for Nissan Frontiers and older Pathfinders. I attached an install video for the # 118670 for you to check out as well.
view full answer... - Trailer Wiring Harness for 2014 Infiniti QX60Confirmed wiring harness fits for your 2014 Infiniti QX60 are shown on the linked page. If you have the factory tow package use # 118273. If you do NOT have the tow package use instead # 118670. 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. It is not a confirmed fit for your 2014 Infiniti QX60.
view full answer... - Which is the Correct 7-Way Trailer Wiring Harness for a 2018 Nissan PathfinderIt definitely sounds like you have experience dealing with at least some aspect of wiring as you are taking all of the correct steps to try and remedy the situation. I have a few things for you to check but for starters, I see that you are using the Replacement Wiring Harness for Tow Ready Nissan Vehicle Wiring Harness part # 118267 which is part of the T-One Vehicle Wiring Harness with 7-Way Trailer Connector part # 118266. The problem is that these wiring harnesses are listed as a fit...
view full answer... - Recommended Trailer Hitch and Wiring for Max Towing Capacity on 2018 Nissan PathfinderI took a look at the online version of the owner's manual for your 2018 Nissan Pathfinder and it states that the vehicle has a maximum towing capacity of 6,000 pounds. I do recommend verifying this in your copy of the manual as well. For a trailer hitch that will work perfectly I recommend the Curt Class III Trailer Hitch Receiver # C13309 which has a 6,000 pound capacity to match the Pathfinder's limits and a nice hidden crosstube design where only the 2 inch receiver will be visible....

- Does Draw Tite Trailer Hitch for 2015 Nissan Pathfinder have Capacity to Tow 4,500 lb TrailerThe Draw Tite trailer hitch part # 76031 that you referenced has a 6,000 lb towing capacity which would be more than enough for a 4,500 lb trailer. I looked up your 2015 Nissan Pathfinder and it should have a towing capacity of 5,000 lbs which would work with a 4,500 lb trailer as well. For trailer wiring you'd then want the # 118273. I attached an install video for this for you to check out as well. Since you wanted to do some towing you might be interested in etrailer ball mount kit...
view full answer... - Trailer Hitch and Wiring Recommendation for 2017 Nissan PathfinderFirst for a trailer hitch the Draw Tite hitch part # 76031 is a confirmed fit and will work great. It has plenty of capacity at 6,000 lb trailer weight and has the best price. For trailer wiring you'd then want the # 118273 and you'd be set. 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 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch...
view full answer... - Where to Install Two Blue Relays From Tekonsha Vehicle Wiring Harness for 2016 Nissan PathfinderThe Tekonsha T-One Vehicle Wiring Harness # 118273 that you referenced is confirmed to fit your 2016 Nissan Pathfinder. It's very possible that the remaining two blue relays that you mentioned might not actually be needed. In some models, the necessary relays are already present in the relay compartment under the hood. In these cases, the two included blue relays simply aren't used. I recommend proceeding from here by just checking that that everything works fine with your trailer connected...
view full answer... - 7-Way/4-Pole Combination Wiring for 2018 Nissan PathfinderAll trailer wiring parts for the 2018 Nissan Pathfinder appear on the linked page. These include the item # HM40975 which is a Replacement combination 7-way/4-pole connector intended as a factory replacement. If you have no trailer wiring you can instead use kit # 118273 which includes relays, wiring and the trailer connector along with the part # HM40975 which will replace the 7-way included in the kit t give you both types of connections.
view full answer... - Recommendation for Installing 4-Way and 7-Way to 2014 Nissan PathfinderIf you want to install the Hopkins 7- and 4-Pole Trailer Connector Socket # HM40975 on your 2014 Nissan Pathfinder, but it does not feature the OEM socket that it connects to, you will just need the Tekonsha T-One Vehicle Wiring Harness # 118273. This custom-fit harness will connect to the built-in port on your Pathfinder located under the vehicle, on the passenger side. Then, instead of using the included 7-Way that comes with the harness, you will install the Hopkins # HM40975 instead....
view full answer... - Replacement Trailer Wiring Harness for a 2014 Nissan PathfinderThe complete wiring harness and relays needed for your 2014 Nissan Pathfinder is # 118273. Unfortunately, the # 118267 is not the direct replacement part that will work on your 2014. It's the direct replacement for # 118266 for older model Pathfinders and has a different wiring layout. There isn't a replacement harness for the # 118273.
view full answer... - How to Install a 7-Way and a 4-Way Trailer Wiring Connector on a 2015 Nissan PathfinderSo that you could have both a 4-way and a 7-way connector at the rear of your 2015 Nissan Pathfinder you would want the part # 118273 which is a kit that will install a 7-way, but instead of using the 7-way that comes with it you would install the # HM40975 instead. The round connector of the # 118273 will plug right into the # HM40975 and will allow either connector to be functional.
view full answer... - Adding a 7-Way Trailer Connector to a 2014 Nissan Pathfinder without Factory Tow PackageSince you do not have the Nissan factory harness on your 2014 Nissan Pathfinder you will need to use a different wiring harness, # 118273, which includes all the parts needed to add a fully functional 7-Way trailer connector to the rear of the vehicle. It does use those gray and black connectors to install as well.
view full answer... - Parts Needed to Add 4 way and 7 way Connector for 2019 Nissan PathfinderIn order to install a 4 way and 7 way connector on your 2019 Nissan Pathfinder you'll want to use the Tekonsha # 118273 which comes with all of the plugs needed to connect to the factory wiring. Once you've done that, you'll want to not install the connector socket that came with the package and instead use the Hopkins # HM40975 which is a connector socket that comes with both the 4 way and 7 way connections. This will allow you to tow trailers with both a 4 way or 7 way connector.
view full answer... - Trailer Hitch and Wiring Harness for 2019 Infiniti QX60 and Length of Wiring Harness 118267The cord of the Replacement Wiring Harness for Tow Ready Nissan Vehicle Wiring Harness # 118267 measures 40 inches, and the overall length including the plug is 42-3/4 inches. In regards to your 2019 Infiniti QX60, the 7-way wiring harness is the T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118273. For a hitch the best option is the Draw-Tite Max-Frame Trailer Hitch Receiver # 76031. I've added links to video reviews for you to check out as well.
