CURT Custom Fit Vehicle Wiring - C56173

  • 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.


Features:

  • 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
    • Locate connection points in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading 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


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. To locate this harness, you will have to remove the rear scuff panel in your trunk and pull back some of the trunk liner. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


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


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.

Hopefully this is not too critical. The harness seems to do the job but the connectors do not click in like the factory ones. Not 100% confident that they will stay connected.

It might put your mind at ease to know that we request reviews on year post purchase and we have never heard of anyones connectors coming apart.

Honda Odyssey

Hooked up one (Honda Accord) of two we bought, the hitch installed relatively easily and works like a champ. I haven’t been brave enough to rewire and install the trailer light kit yet.



The second hitch we bought (Honda Odyssey) is still in the box. Turns out we probably did not need it and will wait until we eventually buy a new Odyssey some day.

The C56173 harness works great on my 2013 Honda Accord EXL V6 model with LED tail light. It was easy to install thanks to connectors that fit as advertised no cutting required. You do have to run a 12 volt power cable from the battery to the trunk. This was easily accomplished using my oil change ramps purchased from Auto Zone to get under the car. Once elevated I was able to slide under the car and route the +12 volt wire from the battery to the rear of the car along existing paths excellent for tie wraps. After you get your 12 volt wire to the rear of the car there are existing factory holes along the left side of the trunk with rubber grommets that allow you to get the wire into the trunk without drilling. I would recommend this quality product for purchase.

2013 Honda Accord

This vehicle wiring harness was a replacement for the harness I had purchased and had installed by the dealership when I bought the car new. Unfortunately, that had been the wrong kit. Didn't realize at the time the car was purchased that it had LED taillights. As a result, while the turn signals and brake lights on my trailer worked, the taillights did not. This new kit for 2013-15 Honda Accords with LED taillights installed easily and now all the lights function perfectly.

by:

I ordered the wrong wiring harness by mistake and they were very help full in returning and reordering the correct harness. It all went together as per instructions. I also ordered a trailer hitch that was very easy to mount. Great company!

2017 Honda Accord

Works perfectly for 2017 Honda Accord Hybrid. Installation directions were easy to follow. Hardest part was to run the cable from the trunk to the battery which took some time. Other than that, works with no issues.



by:
2013 Honda Accord

THE HITCH INSTALLED WITH NO PROBLEMS. REGARDING THE HEAT SHIELDS I ONA HAD TO MAKE A SMALL NOTCH ABOUT 1 1/2 INCHES LONGAND BEN THE METAL AWAY.
THE WIRING WENT A LITTLE HARDER BECAUSE I HAD NO HOIST TO RAISE THE CAR UP. I TRIED TO RUN THE POS. WIRE FROM THE BATTERY INSIDE BUT FOUND THAT TO DIFFICULT SO I RAN IT UNDER THE CAR IN JACKED LINE CORD. EVERY THING CHECKS OUT OK. WILL HAVE TO WAIT FOR MY TRAILER. LEN J.



by:

Plug in wiring went very well. I should have looked into how to remove buttons frist as I broke several before I figured it out. Running the 12 VDC power wire was the hardest part of the job. Install hitch also which went very well. Very happy with etrailer.com service.



by:

Installation was fairly easy, the hardest part is running the power line up to the battery, I ran the power cord under the car inside of a plastic wire protector, that made the installation much easier.
The rest of the unit plugged right in and worked perfectly.
I am very satisfied.

If it weren't for the fact of having to run a hot wire from the battery, the installation on my 2015 Accord was easy thanks to good installation instructions

  • Which Trailer Wiring Harness for 2014 Honda Accord LX with LED Taillights
    The issue is the bulb style you have in your 2014 Honda Accord LX. Since you have LED taillights the correct kit you should have went with was the part # C56173 which was designed specifically for vehicles with LED taillights.

  • Trailer Wiring 4-Way Recommendation for 2015 Honda Accord with LED Taillights
    Since your 2015 Honda Accord has LED taillights you'll have to go with a trailer wiring harness that is designed to fit that style of lights. You'll need the part # C56173 which would not be what would have been the listed fit for a 2014 Accord with incandescent taillights. This kit can easily work with trailer taillights that are LED or incandescent.

Per Curt all non-trailer loads - bike racks, cargo carriers and so forth - should be supported with stabilizing straps like part # 18050. Failure to properly support these loads will void your hitch warranty from Curt. You can also order the hitch with a Euro drawbar and hitch ball or a hitch with a standard drawbar.

  • How to Tell LED From Incandescent Taillights to Choose Trailer Wiring Harness on 2015 Honda Accord
    There a few different ways to determine this. You can have a helper activate the turn signals, running lights and brakes. If a single bulb lights for each function (on each side of the car) then you have incandescent lamps. If you have LED's each function will be illuminated by many, smaller lamps. I'll provide you with a photo showing an incandescent lamp next to an LED version of the same lamp. The lamps shown are on a trailer, not a car but you'll get the idea. Or, you could open the...

  • Why is Powered 4-Pole Trailer Wiring Harness Necessary on 2016 Honda Accord with LED Lights
    Some vehicles need a powered trailer wiring harness with a separate power wire (rather than the passive type that just plug-in) in order to protect the car's wiring. In the case of the 2016 Honda Accord sedan this is the type of harness required, either Curt # C56299 if you have the hybrid model or the # C56173 if you have the hybrid model. I linked an article with tips for routing that power wire. The reason a powered harness is required is that the vehicle's internal wiring is of too...

  • Recommended Trailer Wiring Harness For 2017 Honda Accord Coupe
    The trailer wiring harness you asked about, part # C56173, is designed to fit the Honda Sedan only and is not a fit for your Coupe. I do have a harness that will work for you. I recommend the Vehicle Wiring Harness # C59236. The installation of this kit does require hard-wiring. It sounds like you plan to do some light towing. I recommend the Curt Trailer Hitch, part # C11496. This is a Class l trailer hitch and it has a 1-1/4-inch receiver opening. For a ball mount to use in the hitch...

  • Trailer Wiring Recommendation for 2015 Honda Accord With or Without LED Taillights
    The LED taillight distinction that the Trailer Wiring Harness part # C56173 has refers to the vehicle. So if your 2015 Honda Accord has LED taillights this is the correct kit you'd need. If instead your Accord does NOT have LED taillights the kit you'd need is the part # 118596. Either kit works great with LED trailer taillights.

  • Hitch and Towing Setup Recommendation for a 2015 Honda Accord Coupe
    The Curt item # C11496 that you referenced does not include the recommended ball mount, part # 3593. With a Class I hitch like this you can only use the recommended ball mount for the hitch. For a hitch ball you would want the part # 19256 for a 1-7/8 inch ball or part # 19258 for a 2 inch hitch ball. If you have a coupe with LED taillights you would want the part # C56173 for trailer wiring or part # C56011 for with incandescent bulbs.

    The Curt hitch part # C11681 is the most popular hitch we offer for your 2014 Honda Accord and only requires you trim the heat shield as far as permanent modifications go. There wouldn't be any drilling or rear bumper trimming. The exhaust does have to be temporarily lowered but that is pretty standard for trailer hitch installs. I attached an install video for you to check out as well. For trailer wiring you would want the part # C56011 for if you do not have LED taillights or part #...

  • Wiring Hot Lead on 2013 Honda Accord
    To route the black hot lead wire on the wiring harness with 4-pole flat trailer connector, part # C56173, which you reference, on your 2013 Honda Accord you will want to either route the black wire through a grommet and along the exterior frame or follow the existing wiring along the thresholds into the engine compartment up to the battery avoiding areas that may pinch or break the wire.

  • Recommendation to Transport Motorcycle with 2014 Honda Accord
    The available trailer hitches for your 2014 Honda Accord Sport are all Class I hitches that feature a 1-1/4 inch receiver opening. The Curt Trailer Hitch # C11496, which is confirmed to fit your vehicle, has a 200 pound tongue weight capacity. There is not a trailer hitch available for your vehicle that features a higher tongue weight capacity. This is likely because the vehicle itself is not rated for heavier loads, as hitch manufacturers will typically try to match hitch capacities with...

    There are two different trailer wiring harnesses available for the 2014 Accord. The wiring harness you need will depend on whether or not your Accord has LED taillights. If your vehicle has regular incandescent taillights, use part # 118596. Or, if you DO have LED taillights, use part # C56173. Both trailer wiring harnesses would plug inline with the wiring harness that feeds the taillight assemblies. A wire will need to be ran under the vehicle up to the battery. I've linked you to a...

They are both identical in Class and weight ratings and come with a 1-1/4" receiver. Please note that Class I trailer hitches are only rated to carry up to 2 bikes.

    No, there is no fuse that you will need to add for Curt wiring harness # C56011 to work on your 2013 Honda Accord. The trailer lights are powered by the vehicle tail light wiring. This wiring harness was designed to work with sedan models that do NOT have LED tail lights. If your vehicle is a sedan and it does have LED tail lights you would use # C56173.

So as long as your combined weights were under that it would be safe. To do this you need a trailer hitch and the Curt # C11496 is a fit for either the sedan or coupe version of your '15 Accord. You also need wiring to add a 4-flat to your Accord and power your trailer's lights, part # HM11143165...
