CURT Custom Fit Vehicle Wiring - C56267

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing required
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module pulls power from your car's battery to avoid overloading the vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 3.0 amps per circuit
    • Tail lights: 6.0 amps per circuit
  • Limited 1-year warranty


This custom-fit T-connector plugs into your vehicle's wiring harness, which is located on the driver's side and passenger's side of your rear cargo area. You will have to remove the floor coverings and storage trays to access these connection points. Once you've plugged in the T-connector, locate the single-pin connector on your tail light wiring harness and plug in the single-pin connector on the T-connector. Then locate the fuse box under your vehicle's hood and plug in the provided fuse.

Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.

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.

Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.

Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.

Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.

Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Easy to install and perfect fit both the hitch and wiring.


See my review regarding the entire Curt hitch system that was posted a moment ago. That review similarly applies to the wiring harness system in every respect. The instructions for the wiring harness installation were spot on and everything one needs to install it were included. Great and fast service from


Delivered ahead of time in perfect condition. The wiring harness was very easy to install.

2015 Nissan Murano

First of all the service and staff was excellent. I ordered the receiver and wiring on Thursday and it arrived Tuesday evening.
This was a simple installation and took about 15 minutes. Installed on brand new 2015 Nissan Murano. Putting the tiny tie wraps on took more time than anything. I wish the trailer lead plugged into the module l so one could easily route wire to remain outside the vehicle. But if you don't tow all the time it is not a big deal.
The installation of the 75952 receiver took about 20 minutes. I used my motorcycle jack to raise receiver into proximity position then caught a bolt on each side so I could remove jack. Good thing I still had my torque wrench and kreeper from my racing days. You can rent or borrow a torque wrench at A******* A*** if you don't have one.
I did back my car up on a couple Rhino ramps to give me plenty of room to work. Overall I am very pleased with this product and installation. I saved $245 by buying from etrailer and installing myself. I had 2 other hitches including another Murano installed and I am kicking myself I did not do this before.

With the money I saved I can put new tires on my Goldwing! :) Great Job etrailer!!

Still works perfectly with no problems.
Wendell H - 02/09/2018


Not yet installed, but having done several on friends and my own vehicles, I know installing the wiring kit will be the harder part of the installation of a hitch package. All of the wiring kits I have installed work perfectly.


Worked perfect. I'll never pay someone to install hitches and integrated lights again as it was so easy to watch installation video and instructions and DIY it!


Easy to install. Directions were fantastic. Works like new after one year!

2010 Nissan Murano

Good instructions, good product. Hardest removing trim pins, thank YouTube.


This receiver and trailer wiring harness connector have been doing well. I’ve used my trailer with this self-installed etrailer equipment with no issues. I’m a repeat customer and like this past purchase, have been very satisfied with the high product quality and service. And, pricing has been the best around.

Ive only used the Curt Etrailer wiring harness a couple of times in the past year. It has worked flawlessly each time. Thanks again!

2018 Nissan Murano

Super Easy install and instructions were spot on. Instructional videos are very thorough. I absolutely advise you take the time to make sure the threads are clean as suggested in the video. This will make starting the bolts much easier. The passenger side is a bit tight with regard to maneuvering the hitch into place. Can't believe some of the quotes I got from local retailers to install (with all respect to their expertise and business acumen).


Perfect compatibility and an easy installation. The video instruction was excellent. Works great with my trailer.

2019 Nissan Murano

Fast delivery Great price and tons of info on installation
15 minutes installing this on a 2019 Murano
The Murano had a fuse installed from the factory under towing


This was my fourth time buying from etrailer and they always satisfied my needs. This was so simple to install. They are always great to deal with.
This product installs so simple and easy. Highly recommend it.

Still working great. Have not had a single issue
Bill - 12/01/2021


Easy installation with clear instructions.
snap right in place with plenty of extra wire to work out routing.
Although the installation instructions don’t mention it, there’s an extra (larger) ring connector in the kit that was useful in attaching the ground wire to an existing frame bolt.

2018 Nissan Murano

Very impressed with this wiring harness kit!! It included everything needed for a successful install. No splicing required. The instructions with illustrations were perfect for our 2018 Nissan Murano.

2020 Nissan Murano

Super easy and perfect fit. Great instructions. I needed a bigger ground connector and it was included!


Easy install. Better than other brand I installed on a different vehicle.


Very easy to install Instructions were clear.


Very easy to install!

2018 Nissan Murano

Loved that I didn't have to run a wire to the battery, was able to find a way to route wires to outside and use mounting brackets for clean installation. Again videos are a huge help and accurate


Installing it was simple and fits excel lent


Excellent product. Instructions were easy to follow, had harness installed in a very short time. After a year everything is still working great. Great price too. Highly recommend this.


Very satisfied with the wiring harness kit. Everything needed was included and the directions made installation easy.

2021 Nissan Murano

Every thing was GREAT.. Could not have gone any better..Me being 85 years young
installed the wiring Harness in about 1 hour and my Son did the Hitch in about
20 Minutes..All done without any trouble at all,and it looks as if was done by
a professional..Thanks E-TRAILER for a very good Product..

  • Fuse Installation For A Curt T-Connector Harness Part # C56267 On A 2017 Nissan Murano
    No, you do not need to replace the 30 AMP fuse located in your vehicle's fuse box with the provided 10 AMP fuse on the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C56267. The extra fuse is provided for situations in which their is not already an existing fuse in this location. According to Curt, the 30 AMP fuse in the vehicle is also sufficient for the circuit.

  • Does Battery Have to be Disconnected to Install Wiring Harness in 2020 Nissan Murano
    Thanks for the purchase of the Draw-Tite Trailer Hitch # 75952 and Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56267 for your 2020 Nissan Murano. And yes, you definitely should disconnect the negative battery terminal before installing the harness; pulling the towing fuse would not have the same affect. The reason is if you don't disconnect that battery harness there is a possibility of a short that could damage the harness or other electrical systems...

  • How to Transport a 500-LB Motorcycle with a 2020 Nissan Murano
    I have a possible solution for you. It looks like neither your Curt Class III, part # C13205, nor your vehicle are able to support that kind of tongue weight. Your best bet is to use a motorcycle trailer which you can find online. For most of these, you will need some wiring attached to your 2020 Nissan Murano to power the lights. I recommend the Curt T-Connector, part # C56267. It includes a tail light converter to ensure that your vehicle's wiring matches the one from your motorcycle...

  • Can Curt T-Connector C56267 Be Used On 2015 Nissan Murano Being Towed By Motorhome?
    I have a different option for you, but the Curt T-Connector Wiring Harness # C56267 you were looking at for your 2015 Nissan Murano is for towing a trailer and will not work for powering the lights while being towed behind your Class A motorhome. I looked up your Murano and it is not a vehicle that can be flat towed so as such there are not wiring kits or base plate kits available for it. Instead you will need to go with a tow dolly such as the Demco Kar Kaddy X Tow Dolly # DM9713093...

    Good news! The Curt # C13205, which is a fit for your 2020 Nissan Murano, will still allow you to use the hands free lift-gate feature. While the area directly above the hitch receiver may not be fully functional, you'll still be able to kick your foot to the left or right of the receiver to operate the hands-free lift gate. The Curt # C13205 is a Class III hitch with a 2" receiver that has a durable gloss black powder coated finish that will provide superior resistance to rust and corrosion. If...

  • Recommended Trailer Hitch for a 2020 Nissan Murano
    The Draw-Tite Max-Frame Trailer Hitch Receiver part # 75952 is what I recommend for a 2020 Nissan Murano because it has a durable powder coated finish that will look very nice on the rear of a Murano (see photo) and it has an integrated trailer connector mounting tab which cuts down on the total numbers of parts needed for towing. The Draw-Tite hitch offers bolt-on installation with no cutting or drilling required therefore you aren't making any permanent modifications to the vehicle. If...

    For your 2015 Nissan Murano you will need the Curt Hitch part # C13205 as it has been confirmed as a fit for your vehicle. The # 13577 does not fit the 2015 models so there is no way to use it on your new Murano. I attached an install video for you to check out as well. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900.

If you'll also be towing with the hitch sometime in the future, you'll need a few other items to complete your towing setup.

    A trailer hitch from a 2013 Nissan Murano won't fit a 2020 Nissan Murano as the vehicle underwent a generation change in 2014, so the spacing and frames are different, necessitating different hitches. The hitch I recommend for your 2020 Nissan Murano is the Curt Trailer Hitch Receiver # C13205 or etrailer Trailer Hitch Receiver # e98907.

  • Trailer Hitch Receiver, Ball Mount and Wiring Harness Needed To Trailer Tow With 2023 Nissan Murano
    First you will need the etrailer Trailer Hitch Receiver # e98907 to attach to your 2023 Nissan Murano. This will give you a 2" opening for a Brophy Ball Mount # BM20 and either a 1-7/8" # 19260 or 2" # 40038 hitch ball to match your trailer coupler. The Curt T-Connector Vehicle Wiring Harness # C56267 will give you a 4-way flat connector. This is the most common connector used on small trailers you will tow.

  • Troubleshooting Installation of Curt C56267 Where Trailer Lights Do Not Work
    I would start by testing the power wire that you connected that carries the 12v power to the Curt # C56267 harness using a circuit tester like the # PTW2993; this will tell you if there is even power being supplied to the harness, which I suspect might be the cause of this issue. If you test the wire and it's not giving you 12v of power, you'll need to run a wire up to the vehicle battery with some 12 gauge wire # 12-1-1 and connect it with a ring terminal like the # DW05705-1.

It sounds like you have an issue with the wiring on your trailer, not your Murano. You can confirm this by using a Circuit Tester, like part # PTW2993, to test the 4-Pole connector on your Murano and using a 12V power source, like your Murano's battery, to test the 4-Pole connector on your trailer side.
