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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56173 Review

Today we're reviewing part number C56173 from Curt. This is a T connector vehicle wiring harness with a 4-pole flat trailer connector. It's made specifically for the Honda Accord beginning in model year 2013, and it works with the Honda EX, EXL, V6, and Touring Accord with the LED lights. You'll want to use the etrailer.com fit guide to find out whether your vehicle, your model of Honda Accord will work with this part. This is an easy way to provide power to your trailer for your signal lights using this 4-pole flat trailer connector. The 4-pole does come with a dust cap to protect it when it's not being used.

And of course, when it's not being used, you can just store it in the back of your vehicle. The wiring for the trailer connector comes into this power converter. On the other side of the power converter you have two bundles of wires. The bundle with the yellow wire is the driver's side wiring, and you want to install that first. So take off the back of the taillight cover and you'll find a wiring harness.

Simply unplug that. And then plug these two sets of plugs into the wiring harness on that side. You have two white plugs and two gray plugs. Once you've done that, take the green wire, and run it over to the passenger side and do exactly the same thing. Take off the back of the taillight cover, and then unplug the wiring harness and plug these two gray plugs in.

This is how you get the name T connector, if you can see, because of the shape. Now the white wire over here is your ground, and that should be installed on a clean, unpainted surface using the self-tapping screw that's included. And then you have finally the power cord, the black power cord which comes out of the power converter. Now notice that the power converter has an explanation on the face of which wires power which function. And what this part does is, it prevents overload in your vehicle's electrical system when you are using the 4-pole connector to tow.

So the way you connect your black power wire to your battery is to take one end of the long black wire that's included in the kit, connect these two wires together using one of the two included bud connectors. Run the long black wire up to the front of your car. I'm sorry. I neglected to say you do want to install the power converter using the double-sided sticky tape that comes in the kit. So you run the long black wire up to the front of your vehicle, go under your hood. And the way you connect the other end of your wire to your battery is first connect it to either one of these two wires that are attached to the inline fuse holder. So let's say you attach this one, and you use the other bud connector for that. And then the other wire is connected to your battery using the ring terminal with the yellow shank. The fuse for the inline fuse holder is included here. The kit also includes clearly printed instructions with color photographs. And you do get cable ties to take up any slack in the wiring while you are installing. So once you have installed these parts and gotten the black power wire connected to your battery, you're ready to go. This kit is made in the United States, and it comes with a limited 1-year warranty. And there you have it for part number C56173, the Curt T connector vehicle wiring harness for your Honda Accord.

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. 329082

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. 314760

The kit for led tail lights was a great package everything was included! Very easy to install but a little time consuming running the power wire 290175

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. 281283

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. . 248954

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. 212710

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. 94289
