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. 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.

  • Why Does the Curt Hitch for a 2025 Honda Civic Hybrid Say Not Intended?
    Hey Abel! The Curt Hitch item # C92UR will fit the hybrid model of the 2025 Honda Civic, but there's an extra step when installing it. You have to do some trimming of the bumper area to accommodate the 1-1/4" receiver. That's why it says it isn't intended. The Curt Hitch item # C92UR is custom fit for the 2025 Honda Civic hatchback and sedan. This is a class I hitch with a 1-1/4" receiver. It has a 2,000 lbs towing capacity and 200 lbs maximum tongue weight. I have linked an installation...

  • Best Hitch for 2022 Honda Civic Sport Sedan
    Hi Jessie; the best hitch for your 2022 Honda Civic Sport Sedan is the Curt # C92UR. This has the same specs as the Draw-Tite # 24954 you looked at with a 1-1/4" receiver and 200/2,000 lb max tongue/trailer weight. However, Curt tends to add a thicker powder coat so it holds up better over time. By "light" did you mean wiring for trailer lights? If so, you can use the Curt T-Connector Vehicle Wiring Harness # C43VV. This plugs into the connection points behind your tail lights and will...

  • Does The Bumper Need To Be Cut To Install a Trailer Hitch Receiver on a 2022 Honda Civic Hatchback?
    Both the Curt # C92UR receiver you found and the Draw-Tite # 24954 are going to require slight modification to the steel bumper and plastic fascia to fit your 2022 Honda Civic Hatchback. I have linked an installation video near the bottom of the page for a similar Civic which will show you what all is required. If this is something you are not sure you have the skills to install yourself you can also use our installer link located near the video to locate installers in your area. I do...

  • Trailer Hitch Receiver and 4-Way Vehicle Wiring Harness For a 2024 Honda Civic
    Yes, we have the Curt Trailer Hitch Receiver # C92UR which fits your 2024 Honda Civic as long as you don't have a center exit exhaust. If you have the center exit exhaust you will have to modify the exhaust to make any receiver work. I recommend installing the 4-Way Wiring # C43VV when you install the receiver. This is the most common connector used on most small trailers. And it will also allow for Auxiliary Lights # C53201 should you have a hitch mounted accessory like a bike rack which...

  • Will the Draw-Tite Hitch 24954 Fit a 2024 Honda Civic Hatchback?
    Yes, it will so long as you do not have center exhaust! The Draw-Tite Hitch item # 24954 has been confirmed to fit all models of the 2024 Honda Civic including the hatchback. This is a class I hitch with a 1-1/4" receiver. It has a 2,000 lbs towing capacity and a 200 lbs maximum tongue weight. If you are planning on towing you will also need a wiring harness item # C43VV and the Draw-Tite Drawbar item # 3593 and then for hitch balls item # 19258 for a 2 inch ball or item # 19256 for a...

  • Recommended Hitch and Shipping Weight for a 2024 Honda Civic Hatchback
    The Curt Trailer Hitch item # C92UR weighs 21 lbs. This hitch has been confirmed to fit the hatchback models of the 2024 Honda Civic. If you are planning on towing you will also need a wiring harness item # C43VV and the Draw-Tite Drawbar item # 3593 and then for hitch balls item # 19258 for a 2 inch ball or item # 19256 for a 1-7/8 inch ball.

  • Parts Needed to Tow a Tent Trailer with a 2022 Honda Civic Sport
    Hey Amy, thanks for reaching out! To tow a small trailer with your 2022 Honda Civic Sport you need a trailer hitch, wiring, and a ball mount: - Curt Trailer Hitch # C92UR - Curt T-Connector Wiring # C43VV - Ball Mount (see attached article) The hitch can tow up to a 2,000 lb trailer but from what I saw online your vehicle can only handle 1,750 lbs so that will be your limiting factor - you also need to confirm this in your copy of the owner's manual. The wiring tees in behind your...

  • Solution for Lights on 2023 Honda Civic on Tow Dolly
    Hi Byron; to use the lights on your 2023 Civic you would need flat tow wiring. Unfortunately, nobody makes it for the Civic so that won't be an option. The # C43VV you looked at is designed to power the lights on a trailer if you were towing something with your car so that won't work either. If your tow dolly has lights on it like the Demco Kar Kaddy SS # DM9713045 you won't need additional lights. If not, you can use universal magnetic lights like the Flint Hill Goods Magnetic Tow Lights...
