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. You will have to remove all trunk floor coverings, trim cover, and the tail light assemblies to access this harness. 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.

Great! No problem whatsoever!

Well made. Installation of the line to the battery under the car a bit difficult, but not the fault of the product, as all similar products require this for safety of the vehicle electrical system

It worked great and is high quality. I appreciate being able to plug in this wire harness and not splice the wires. The double sided sticky tape was old and did not stick, but I had already planned on using my 3M double sided tape. The wires were the perfect length for my Honda Accord.

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Is There A 2" Trailer Hitch Receiver Available For a 2018 Honda Accord 2.0 Touring?
    Currently I only see a 1-1/4" Receiver # 24972 available for your 2018 Honda Accord. We do have an Adapter # HT5R which can be used to convert the 1-1/4" to a 2" but this will reduce the rated capacity by 50%. So for the receiver it would then max out at 100lbs of tongue weight depending on your cargo load. I have heard of people either having their own receiver fabricated or altering a receiver with a different Tube # 325-GH-002. But understand this will void any warranty from the receiver...

  • Is Wiring Harness Installed on Outside of 2018 Honda Accord
    I am not quite sure which part you are referring to specifically but the Curt T-Connector Vehicle Wiring Harness # C56402 or T-One Vehicle Wiring Harness # 118776 will install in the trunk of your 2018 Honda Accord, inside the car, as opposed to outside. To complete your towing set up, if you also need a hitch for your 2018 Honda Accord I recommend the Curt Trailer Hitch Receiver # C11525.

  • Will Fascia Still Line Up with Other Panels After Installing a Trailer Hitch on a 2018 Honda Accord
    Yes, the rear fascia will still line up with other panels after installation of the Curt trailer hitch # C11525 on your 2018 Honda Accord. There is enough space in the stock set up to allow for the hitch to fit without compromising the fit of the fascia relative to the other panels. If you tow the recommended ball mount is # 3593 and you can use 1-7/8 inch ball # 19256 or 2 inch ball # 19258. For trailer wiring you can use # C56402 to add a 4-Way connector to the rear of the vehicle.

  • Can 2018 Honda Accord Tow Small Motorcycle Trailer
    We do have hitches that fit your 2018 Honda Accord Sport so with one installed like the Draw Tite part # 24972 you could tow a small trailer like you mentioned. You'd also need trailer wiring like the # C56402 and a ball mount # 3592.

  • Recommended Hitch and Wiring Harness for a 019 Honda Accord Touring Hybrid
    To add a hitch to your 2019 Honda Accord Touring hybrid, you will need the Draw-Tite Trailer Hitch item # 24972 you were looking at. This hitch is custom fit and bolts to your Honda with included hardware. This is a class I hitch with a 1-1/4" receiver and the only available option for the hybrid models.

  • Will The Curt Trailer Hitch Receiver C11525 Fit a 2022 Honda Accord Sport Hybrid?
    Your 2022 Honda Accord Sport being a hybrid will require the Draw-Tite Sportframe Trailer Hitch Receiver # 24972. The Curt Trailer Hitch Receiver # C11525 you received for your 2021 Honda Accord Sport will not fit on hybrid models. The Curt T-Connector Vehicle Wiring Harness # C56402 will give you a 4-way flat connector on your 2022 Accord. This will allow you to connect to the tail lights on most small trailers or use Auxiliary Lights # C53201 if you are carrying a hitch mounted accessory...
