If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Honda Civic (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

The CURT 56324 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Honda Civic (Part #BKDK56324) fits 2016-2019 Honda Civic models. The 2019 model year is the last year covered by this part number. For newer models, check for an updated version.
The CURT 56324 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Honda Civic (Part #BKDK56324) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The Curt 56324 is designed for Honda Civic coupes. The manual specifically lists 'Honda Civic coupe' as the application. If you have a different Civic body style (sedan, hatchback, or convertible), you should verify compatibility with the manufacturer or a fitment database, as the manual does not confirm fitment for other variants.
The Curt 56324 has two amperage ratings: Signal Circuits are rated at 3.0 amps per side, and Tail/Running Circuits are rated at 6.0 amps total. Do not exceed these product ratings or your tow vehicle's lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating and potential fire.
You will need: panel trim removal tool, flat blade screwdriver, wire stripper, crimping tool, and cutting tool. The manual also indicates that a drill may be needed if you must create a pilot hole for the ground screw, though an existing screw with nut in the vehicle frame may be available.
Yes. Step 1 of the installation instructions requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before proceeding with any other steps.
Drilling may be required. Step 7 instructs you to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, you must drill a 3/32" pilot hole for the provided ground screw. Before drilling, you must check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
If an existing screw with nut is not available in the vehicle frame, drill a 3/32" pilot hole for the provided ground screw. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this fuse rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
The harness has color-coded ends: the end with the yellow wire connects to the driver side taillight, the end with the green wire connects to the passenger side taillight, and the white wire is the ground wire. The black converter box is mounted inside the vehicle near the taillight. The black power wire routes from the vehicle battery according to the included CME-PCL-INS sheet (which is not detailed in this manual).
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The manual does not specify exact measurements or orientation, only that it should be mounted on a flat surface near the taillight.
After removing the trunk floor coverings and scuff panels, locate the vehicle's taillight wiring harness connectors behind the taillight housing. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Take care not to damage the locking tabs during separation and reconnection.
When in use, route the 4-flat to the center of the vehicle. When not in use, roll it up and store in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties to prevent tangling and damage.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer. The manual does not provide specific test procedures beyond these methods.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area where you drill the ground screw pilot hole should be free of rust, dirt and paint.
Open the vehicle trunk and remove: the push fastener securing the trunk floor covering, all trunk floor coverings, the storage tray, the scuff panel (by pulling out on the bottom and then up), and the push fasteners from the felt liner on the driver side. Take care not to damage the alignment tabs on the scuff panel when removing it.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no existing screw is available, drill a 3/32" pilot hole for the provided screw. Ensure the area is free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
The Curt 56324 includes: the custom wiring harness with color-coded ends (yellow for driver side, green for passenger side), a white ground wire with ring terminal, a black converter box, a black power wire, a 4-flat connector with dust cover, double-sided tape for mounting the converter box, cable ties for securing loose wires, and a provided ground screw. The package also includes a CME-PCL-INS sheet for battery power wire routing (details not provided in this manual).
