This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the trunk floor coverings, storage tray, rear scuff panel, and felt liner to access this harness. Once you've plugged in the T-connector, run the hot lead 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 rear 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.

  • Is Routing 4-Way For 2018 Honda Civic Coupe Through Back Hatch Better than Through Floor
    Having the 4-way of the Curt kit # C56324 run out of the back hatch is actually the preferred method although it seems like it wouldn't be. Having the 4-way stored inside the cab of the keeps it protected from rain and moisture to prevent corrosion and keeps it protected from damage to the wiring or connector by rocks or debris that might be on the highway. You can run the wire through the vehicle if you wish but just keep in mind that this does take more time and you may end up needing...

  • Does Curt T-Connector # C56324 Fit a 2017 Honda Civic EX Hatchback
    The Curt T-Connector # C56324 that you referenced will fit a 2017 Honda Civic, but according to our fitguide it is only compatible with the Coupe version, not the EX Hatchback that you have. Instead you will need to go with a hardwire option. The Curt option that I recommend going with for your Hatchback is the Powered Tail Light Converter # C59236 because it has a higher amp rating than the other Curt wiring kit # C59496 that fits your Civic. This splices into the tail light wiring and...

  • Trailer Hitch and Wiring for a 2016 Honda Civic Coupe LX
    The trailer hitch for the 2016 Honda Civic Coupe is Draw-Tite hitch # 24954. It is rated for 2,000 pounds gross trailer weight and 200 pounds tongue weight so it can handle the trailer and bike. The recommended ball mount is # 3593 and you can use 1-7/8 inch ball # 19257 or 2 inch ball # 19258. And for a trailer wiring harness use # C56324.

  • Recommended Hitch and Wiring For a 17 Civic Si Coupe
    I spoke to Curt and # C11463 will not fit the Si models. For that, you will need the Curt # C92UR. Please keep in mind this will not fit models with the center exhaust. That being said, there is no trimming of the stock exhaust tips needed. You will, however, need to trim a small part of the bumper for the installation. As to the wiring harness, the coupe will take the Curt # C56324. This is a custom fit harness and, other than a wire that needs to be run up to the battery, will be a plug...

  • Picking Out Trailer Hitch Size and Wiring for 2016 Honda Civic Coupe
    For your 2016 Honda Civic coupe there are only Class I 1-1/4 inch hitches available like the Curt # C11463 which would be a great solution. This hitch will limit you to 200lbs tongue weight and 2000lbs trailer weight, though you want to check the owner's manual for your vehicle and go by the lowest ratings between the hitch and vehicle. Once you know that info you can decide what size/weight trailer will fit the bill for your needs. To complete your towing setup you'll also need a wiring...
