CURT Custom Fit Vehicle Wiring - C56226

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

Quickly and easily install a 7-way, RV-style trailer connector on your vehicle 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.

Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector - C56226

Average Customer Rating:  4.7 out of 5 stars   (131 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!

Excellent customer service. They help find the correct harness for my truck and it installed very easily

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.

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:
2016 Nissan Frontier

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:
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.

Great price, great product, and fast sh ipping.



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.



by:
2012 Nissan Xterra

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:

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.



by:

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

2016 Nissan Frontier

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.



by:

Good installation instructions. Installed in less time than estimated. All parts went together smoothly. I am very satisfied.

2018 Nissan Frontier

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:
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.

More wiring, it works as advertised and the install was made possible by the videos on the the website. You CAN do this stuff and the videos are the help you need

  • Parts Needed to Install Brake Controller on 2023 Nissan Frontier
    Installing a brake controller on your 2023 Nissan Frontier will require a 7-way along with the brake controller itself. Since you do not have the factory trailer connector you will need the Curt T-Connector Vehicle Wiring Harness # C56226. This plugs directly into the OEM tow package port at the rear of your vehicle. For a brake controller, I recommend the Redarc Tow-Pro Liberty # RED24FR. The main unit installs out of sight so only the control knob will be visible in the cab of your...

  • Will the Curt # C56226 and Hopkins # 37575 Work Together on a 2011 Nissan Xterra
    The Curt T-Connector # C56226, which is a confirmed fit for your 2011 Nissan Xterra, does have the correct connection point for the Hopkins Adapter # 37575. I also recommend using the Mounting Bracket # PK12711U and No-Drill Mount Bracket # 18140 for a clean and easy installation.

  • Availability Of Replacement Relays For Aftermarket Tow Package On 2006 Nissan Frontier
    You sure can! The relays found in the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # C56226 can be purchased separately using the Curt Relay Kit for Nissan Aftermarket Tow Package # C57000. I included videos of the products mentioned for you to take a look at.

  • Constant Power on Blue Trailer Brake Wire After Installing 7-Way on 2012 Nissan Frontier
    On wiring harness # C56226 the larger brown relay is for the 12 volt circuit on the 7-Way and the two smaller blue relays are for the turn signal circuits so none of them would cause the constant power draw on the blue brake wire but I think I know what the problem is. On some Nissan vehicles the connectors where the 7-Way plugs in are wired differently than on other Nissan vehicles. To fix the issue you can swap the blue and black wires on the harness that plugs into the vehicle.

  • Will Relays Be Needed to Upgrade Existing 4-Pole Trailer Connector on 2014 Nissan Frontier to 7-Way
    If the relays and jumper harness used with the 4 pole like # C56226 (see linked install video) are already in place behind the passenger side kick panel, then the Tow Ready # 118267 will work just fine. If your aftermarket 4-pole simply tee'd in at the junction between the taillight assemblies and the vehicle taillight harness, you'd want to go with the complete kit like # 118281

  • Does 2009 Nissan Xterra Require Converter For Trailer Wiring Harness?
    Your 2009 Nissan Xterra does not require a converter for a trailer connector.

I included a video of the # C56226 for you to take a look at.

    Thank you for all of the details. I'm glad to hear that all of your lighting functions are working properly. That takes quite a bit of troubleshooting out of the equation.

    We offer several choices in a 2-inch Class III hitch for your 2008 Nissan Xterra X and you can see these by clicking on the link provided.

    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. All you will need to add to your 2008 Nissan Pathfinder is the Curt T-Connector Vehicle Wiring Harness item # C56226 you mentioned. This 7-way harness works with the Pathfinders that came with the towing package. I have linked a couple of installation...

  • 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.

    For a 7-way to replace the 4-way trailer connector you have you would need the Curt Harness part # C56226 that comes with the 7-way and the needed wiring. You will need to cut off the 8-pin connector under the rear of your vehicle that this would normally plug into and then cut off the gray connector of this and hardwire the two together by function. Then to install a Tekonsha brake controller like our super popular P2 part # 90885 all you would need is the correct install harness part...

This right-angle bracket will allow you to mount the connector under the rear bumper of your Nissan Frontier and features a black, epoxy coating to protect against rust and corrosion. The necessary hardware is included. For a no-drill installation, you can add the No-Drill Mount Bracket # 18140. I have attached...
