2017 Nissan Frontier - Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector

  • Trailer Hitch Wiring
  • 7 Round - Blade
  • No Converter
  • CURT

Quickly and easily install a 7-way, RV-style trailer connector on your Nissan Frontier with this custom harness. Connector plugs directly into OEM tow package port - no cutting, splicing or tapping required.


Features:

  • Provides a 7-way, blade-style trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point along frame rail
    • Plug in connector
  • Includes relays required to activate functions
  • Comes with protective cover for 7-way connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your factory tow package wiring harness, which is located beneath the rear of your vehicle, along the driver's-side frame rail. Before connecting the 7-way itself, plug the included harness with relays into the 12-pin connector at the front of your vehicle. To access this connector, you will have to remove the passenger's-side sill plate and kick panel.


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 plug on your automobile and the 7-pole connector itself - to help prevent corrosion.

Average Customer Rating:  4.7 out of 5 stars   (132 Customer Reviews)

Shipped quickly and arrived intact.

This
wiring harness was very easy to install.

Tips:
1: Remove your spare tire before installing this harness. You will have much more room to work under the bed.
2: The safest and most secure way to mount the 7 way connector is by drilling a 2" hole in the bumper to the left of the license plate. This keeps the connector protected from below by the step bumper.

Super easy 7 way to install. All the components just plug in and there is no wiring required. My trailer lights work great!

I had to buy all theses harnesses for my 2010 Nissan Xterra about 7 years ago. The elements finally got the better of them. They were easy to replace.

I had bought a Nissan Frontier which had a hitch and 4 plug wiring. When I hitched up my trailer I had brake and blinkers but no running lights. It was no big deal as I run it during the day. Well I got caught in a nasty rain storm and had no running lights and did some research to figure out why I had no running lights. Make a long story short the person or dealer who rigged up the lights never did the correct wiring. This kit is simple and does all the wiring for you as it is truly plug and play! The only thing they could add to the kit is two #14 sheet metal screws only because there are the holes in the bumper for the plate to attach the plug. Other then that the kits is good as gold!



by:

Great products from a fantastic company. The trailer harness and mounting bracket fit perfectly. Hooked up to our trailer and everything worked as it should. Order received on time. I will be ordering a brake controller very soon. Thanks



by:
2012 Nissan Pathfinder

My 2006 Pathfinder had a towing breaker box under the hood so i didn't need the 12 pin connector harness and the instructions did not cover that. Thank goodness for Google! Also some kind of bracket choice would have been nice but i was able to fab my own. Other than that this is a great kit that I'm sure is designed to cover a couple generations.



by:
2014 Nissan Xterra

Great product! Went together as described in youtube video. Only problem I have is the provided zip ties were not long enough to wrap around the tube steel of the hitch. I had to attach 2 together to get the length needed. The ties are also very thin. I will probably re-tie later with longer thicker ties.

Fast shipping and all connections were easy with the instructions. Had the Nissan issue with the swapped blue and black wires but still a easy job



by:

Super easy install, no mount bracket included, decided it would be more protected mounted in the step-bumper

I would be more likely to order again from etrailer if I did not receive so many emails for surveys and pats on the back. I received the first survey request before the item arrived and the second just minutes after. Have not even had time to begin to install items. It feels almost like harassment. I can usually find what I need here but get irritated with constant emails. Probably would rate higher but won’t get to installation for a couple of days and then the products need to prove themselves before a rating can be valid, unless all I’m rating is the delivery. It came as advertised, thought not fast.

2016 NissanFrontier

I have a 2016 Nissan Frontier that I bought used in November 2017. In February 2018, the first time I towed my trailer, I found out the trailer lights didn't work. After trying just about everything, I bought the C56226 wire harness from etrailer. Today, 17 May 2020, my son and I removed the factory installed harness and installed the new one from etrailer. In doing so, we discovered Nissan only installed one blue relay and one brown relay...the other blue relay was never installed! My trailer lights were never going to work! Thanks to etrailer my truck is now the way it should have been the day it rolled off the assembly line...all three relays are installed and my trailer tail lights now work.

Great! One year later and my trailer lights work perfectly.

2006 Nissan Xterra

I was desperate to find a trailer hitch for my Nissan Xterra, due to a last minute change of plans to bring my son home from college.
I found etrailer and they saved the day!
Great price, in stock so I placed my order. It arrived in a day or 2, with no extra charges. It was truly a custom fit for my vehicle with everything needed to hook up and connect to my truck, and was on in no time. Heavy duty/solid construction, a quality piece.
I have made use of the hitch many times, with out any problems!
Very happy with etrailer and I have already recommended them to others.



by:
Nissan Xterra

Finally got time to install the hitch on my '14 Xterra. I found that I did not have to loosen the exhaust. I did it my myself in my garage and it took about an hour. After you wiggle it around and get the first bolt in the rest go in easy. Then all one must do is torque the bolts and you are "golden." I also am installing the 7 pin wiring harness. The Xterra is already wired for towing. It is mostly a plug and play. The only thing I did different was to cut a hole in the bumper and make it permanent and better looking. Will pick up my new teardrop trailer in a couple of months. Everything will be ready to go by then.



by:
2012 Nissan Pathfinder

Still works after a year but I did have a problem with installation on my 2012 Nissan Pathfinder because the Electrical Brake and Power Cables where reversed. Had to switch those two wires because before I did that I could not pull the trailer. The electrical brakes were always engaged.



by:

Great controller ,, easy to set up and with the on line instructions everything went smooth .. only issue is after you set it up check the trailer connector as the MANUFACTURE SWITCHED THE BRAKE WIRES and I had to switch them back .. it locked up the trailer brakes ...Just use the trailer connector tool to make sure everything is good before you go.

This was a really easy and quick installation. Instructions were easy and the pictures with them helped a great deal.

2018 NissanFrontier

When I ordered this item, for obvious reasons as described in the product review...its a plug and play. Bracket not included!! Well ok, so I will pay extra and get the bracket to attach this $75.00 bundle to my hitch. All went well with the order, and arrived in a good amount of time. easy install hooking into the factory connections. But this stupid little made in Taiwan bracket that I had to order above and beyond, mounted to the hitch ok, but was nowhere in the ball park of fitting the hole arrangement on the seven way plug!! I had to drill new holes in the plug itself to get it to mount up correctly. Not a huge deal, but my expectations are that paying the additional amount for an incorrect part...that should come with the product to begin with was somewhat of a let down. I will continue using e-trailer in the future for my vehicle needs. Folks are only getting a three star on this one!!



by:

Everything plugged together as shown in the installation video.



by:
Saturn Relay

Wiring harness and relay harness plugged into the truck perfectly. I had a 7way to 4flat adapter plugged in and there was an issue where the blinkers and brake lights weren't working. Turns out there's a 15a fuse in the engine compartment that was missing. The fuse goes in the smaller fuse box on the passenger side in the engine compartment. Once you plug the fuse in everything will work. Hope this helps someone else.

2014 Nissan Xterra

Purchased a 2014 Nissan Xterra last year and unfortunately it did not come with the tow package. I purchased the CURT hitch along with the CURT custom fit wiring for this vehicle from etrailer.com. Both are now installed and I was very pleased with the ordering process, customized YouTube videos to assist with the installation and most importantly the equipment. We are now ready for our upcoming trip out east pulling a TAB trailer.



by:

The wiring harness and connectors went together very easily. The instructions were easy to follow. After I purchased the product I noticed the vendor had reduced the price and I found less expensive sellers for the same product. I wish the vendor would have given me a credit for the price change.



by:
2012 Nissan Xterra

Plug and play, 1 hour and our 2012 Xterra was ready to tow our new camper, the RV dealership wanted $400-600 to wire it and they were going to hack up my wiring with a universal kit.

This and a Curt brake controller was a piece of cake to install ( after reading the online help and watching the install video.)

  • 7-Way Wiring Harness For 2011 Nissan Pathfinder With Factory 4-Pin Tow Package.
    You are correct, James. The only aftermarket wiring options for the 20111 Nissan Pathfinder are for vehicles without the factory trailer connector. So, you can use the Curt T-Connector # C56226 for your pathfinder, but as you said, this will bypass the current OEM tow package wiring. You should already have the necessary relays installed, so you would just use the 7-way portion of the harness.

  • Part Needed to Add 7-Way to 2011 Nissan Pathfinder
    To add a 7-way to your 2011 Nissan Pathfinder, all you need to do is add the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226. This will replace your 4-way and give you the 7-way you need to tow your camper with electric brakes. You'll then be able to use a brake controller like the Curt TriFlex NEXT # C24VV with Wiring Adapter # C51382.

    The Curt Echo Wireless Brake Controller item # C51180 is controlled through an app on your phone and does not require a connection to a brake controller wire. I am guessing that's what you mean by a traditional brake box and under dash adapter.

  • Parts Needed for 2023 Nissan Frontier to Tow Trailer With Brakes
    Towing a trailer with brakes will require adding a 7-way along with a brake controller. Since you were already looking at 4-way wiring I'm assuming there is no factory trailer connector on his 2023 Nissan Frontier. All you will need to add a 7-way is the Curt T-Connector Vehicle Wiring Harness # C56226. The brakes and the lights aren't tied to the same wires but the 7-way will take care of powering all your lights along with sending power to the brakes. For a brake controller, I recommend...

  • Recommended Wiring Harness And Brake Controller for 2008 Nissan Pathfinder With Factory Tow Package
    For your 2008 Pathfinder I recommend the T-One Wiring Harness with a 7-way trailer connector, part # 118266. This harness plugs into the existing wiring on your Pathfinder and that measns no cutting or splicing into the wiring. This gives you a 7-way at the rear of your vehicle. I also recommend the Pollak mounting bracket, part # PK12711U. The # C56226 harness will also work with your vehicle but we have had very good reviews from customers when using the T-One harness.

  • Are Curt 4-Way Relays Compatible With Hopkins 7-Way on 2017 Nissan Frontier
    The relays for the Curt # C56225 on your 2017 Nissan Frontier are the same as the ones that come with the Curt 7-Way # C56226. Since you already have the 7-way functionality from the relays that came with your 4-way you will be able to install and use the Hopkins # HM43534 without the need for additional parts.

  • 7-Way For 2021 Nissan Frontier Without Factory Tow Package
    We do have an option for you as the Hopkins # HM43534 is only for the factory tow package. So because your 2021 Nissan Frontier does not have the factory tow package, you'll need a wiring kit that includes the relay jumper harness which connects to a 12-pin plug that is behind the kick panel on the passenger’s side in the cab. The correct part to add a 7-way is the following: - Curt T-Connector Vehicle Wiring Harness # C56226 The relays and jumper harness of the # C56226 are not available...

  • Troubleshooting 4-Way to 7-Way Wiring Upgrade on 2006 Nissan Pathfinder
    My first recommended troubleshooting step is to check the relay harness located behind the passenger-side kick panel There should be a harness installed behind this panel with 3 relays installed in the harness. If this harness is missing or any of the relays are not installed, the harness will not work until they are installed. You can check out the harness included in part # C56226. I have attached an installation video of this harness on a 2014 Xterra. While this is a different vehicle...

  • Wiring And Relays Compatible With 2010 Nissan Pathfinder
    Yes. The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226 is a fit for your 2010 Nissan Pathfinder and utilizes the relays you referenced in the Curt Relay Kit for Nissan Aftermarket Tow Package # C57000. The combination of the relays and the wiring will give a 7-way trailer connection to your vehicle utilizing the factory wiring already present.

  • Does 2009 Nissan Xterra Require Converter For Trailer Wiring Harness?
    Your 2009 Nissan Xterra does not require a converter for a trailer connector. It uses the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226 which plugs into the factory connectors in the rear of your vehicle, and the included relay harness activates the circuits. I included a video of the # C56226 for you to take a look at.

  • 7 and 4-Way Trailer Wiring Recommendation for 2006 Nissan Xterra
    If your 2006 Nissan Xterra has a round connector like what you see in the attached picture for trailer wiring then all you'd need is the # 30955 and you'd have a 4 and 7-way setup that will easily install. If instead you have something different you'd want the # 30955 plus the Curt connector kit part # C56226 and you'd be set.

  • Does Curt 7-Way Kit for 2016 Nissan Frontier Have Charge Line for Trailer Battery
    The Curt T-Connector Vehicle Wiring Harness # C56226 that you referenced does have a 12 volt accessory circuit pin which you could use to put a maintenance charge on the trailer battery when towing. This means it would keep the battery topped but wouldn't charge a drained battery. This circuit will only be active when the key of the vehicle is on so it won't drain your Frontier battery when parked.

Then for your trailer brakes, I recommend the Tekonsha Prodigy P3 # 90195 along with the wiring harness # 3050-P if you have that port in your junction box beneath the dashboard, which it sounds like you do. If you don't have that port for some reason, then you would use kit # 5506 to hardwire the controller.

  • Differences Between Curt # C56226 and Tow Ready # 118266 7-Way Connectors for 2012 Nissan Xterra
    Other than the fact that each 7-way trailer connector you mentioned is from a different manufacturer, both the # C56226 from Curt and the # 118266 from Tow Ready would work identically. Either connector would work just fine on your Xterra. You could choose the less expensive Tow Ready model and not feel that you sacrificed anything. If you click the provided link, you can see the # 118266 being installed on a 2014 Frontier. The procedure would be pretty similar on your Xterra.
