4-way flat output connects tail lights, brake lights and turn signals
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 Kia K4 and K5 (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 56562 is a powered converter lead and T-connector harness system that connects a vehicle's taillight wiring to a trailer lighting connector. It allows you to tow a trailer with functioning lights by converting the vehicle's lighting signals (left turn, right turn, brake, and taillight) to a 4-way flat connector for the trailer.
The Curt 56562 is designed for passenger cars with 12-volt negative ground electrical systems. The manual does not specify which vehicle makes, models, or years are compatible. Contact Curt Manufacturing or consult a fitment database with your vehicle's year, make, and model to confirm compatibility before purchasing.
The manual states the product is for passenger cars and does not address compatibility with trucks or SUVs. Consult Curt Manufacturing or a fitment database to determine if a different product or installation method is required for your vehicle type.
The Curt 56562 must be used only on 12-volt negative ground systems. If your vehicle has a different electrical configuration, this product is not compatible.
Required tools are: ratchet, 6-inch extension, 10mm socket, 10mm wrench, drill, 3/32-inch drill bit, Phillips screwdriver, trim panel tool, fish wire, wire cutters, wire crimpers, wire strippers, test light, and multimeter. Proper tools will improve installation quality and reduce time required.
The manual confirms the following items are supplied: double-sided tape (for mounting the lighting modules box), white ground wire with ring terminal, ground screw, cable ties, 4-way flat dust cover, and a 10-amp fuse holder with 10-amp maximum fuse. The manual references a CME-PCL-INS sheet for power lead details but does not list all included components.
Yes. Step 1 requires you to disconnect the negative battery terminal before beginning installation. This is a critical safety step to prevent electrical damage and shock hazards.
Open the rear hatch and remove all floor coverings. Remove the threshold carefully without breaking any mount tabs or pins, and set it aside. Then locate and gently remove the two plastic felt trim panel mounting pins on the driver's side using a trim panel tool, being careful not to break or damage the pins. Pull back the felt trim panel to access the vehicle's taillight connectors.
Locate a clean and flat area near the driver's side taillight connector behind the driver's side felt liner. Mount the lighting modules box using the supplied double-sided tape. Ensure the surface is clean and flat for proper adhesion.
Disconnect the vehicle's wire harness from the taillight connectors. Route the harness with the yellow wire behind the felt trim panel. Insert the lighting modules connector containing the yellow wire carefully, being careful not to break connector locking tabs. Repeat this process for the passenger's side taillight connection.
Route the green wire along the threshold from the driver's side to the passenger's side. Then gently remove the passenger's side felt trim panel pins using a trim panel tool, being careful not to break or damage the pins, and pull back the felt trim panel to access the passenger's side taillight connectors.
Drilling may be required for the ground wire connection. You must locate a grounding point such as an existing screw or bolt in the vehicle frame. If no suitable existing fastener is available, drill a 3/32-inch pilot hole. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it. Before drilling, check for miscellaneous items hidden behind or under any surface to avoid damage and personal injury.
Drill a 3/32-inch pilot hole if an existing screw or bolt is not available for grounding the white ground wire. The area must be free from rust, dirt, and paint before drilling.
When passing the power wire through sheet metal, use an existing grommet, add a new grommet, or use silicone to protect the power wire from sharp edges. This prevents damage to the wire insulation.
Signal circuits (left turn, right turn): 3.0 amps per side. Tail/Running circuits: 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. For more information, check your vehicle owner's manual or contact the vehicle manufacturer.
The power wire is 12 gauge (12 GA) or larger. Route it to the vehicle battery location, taking care to avoid pinch points and hot or rotating components.
Green = Right turn, Red = Brake, Yellow = Left turn, Brown = Taillight. These colors correspond to the vehicle's taillight signals that are converted to the 4-way flat connector for trailer use.
P3 is behind the driver's side taillight housing, inside the trunk. P4 is behind the passenger's side taillight housing, inside the trunk. These are the locations where the lighting modules connectors are installed.
Route the black power wire from the converter to the vehicle battery as shown on the included CME-PCL-INS sheet. On the driver's side, locate a grommet or cargo vent in the body in the cargo area and exit the cargo area. Route the new power underneath the vehicle forward to the battery compartment. Use cable ties to secure any loose wires. Avoid pinch points and hot or rotating components.
The fuse holder includes a 10-amp maximum fuse. Install the fuse after all other installation steps are complete. The battery connection must be fuse-protected.
Attach the ring terminal of the white ground wire to the vehicle body using an existing screw or bolt in the frame, or drill a 3/32-inch hole and use the provided ground screw. The area must be free from rust, dirt, and paint; use an abrasive pad or paper to clean it before securing the connection.
Route the 12-gauge black power wire to the positive battery terminal using a ring terminal connection. The battery connection must be fuse-protected with a 10-amp maximum fuse. Install the fuse after all other installation steps are complete. Disconnect the negative battery terminal before wiring the power wire.
Disconnect the negative battery terminal before beginning installation. Do not lay tools across the positive battery terminal (risk of short, sparks, electrical shock). Do not ground the negative cable to a metal item, as this could damage the vehicle's electrical system. Before drilling, check for miscellaneous items hidden behind or under any surface to avoid damage and personal injury. Route the power wire to avoid pinch points and hot or rotating components. Do not pinch the 4-way harness in the trunk latch.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating can cause electrical damage or unsafe towing conditions.
After installation is complete, verify that the harness is functioning by using a test light, 4-way tester, multimeter, or by attaching the 4-way flat connector to any trailer with functioning lights. All steps must be followed to ensure the product will function properly.
Reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Reinstall all removed items (threshold, felt trim panels, floor coverings) in the reverse order of disassembly. Test the harness using a test light, 4-way tester, multimeter, or by connecting a trailer with functioning lights. Store the 4-way connector in the rear cargo area when not in use.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. This helps maintain proper function and prevents electrical issues.
Store the 4-way connector in the rear cargo area when not in use. This keeps it protected and prevents damage or loss.
The installation difficulty level is rated as Difficult. Installation difficulty levels are based on time and effort involved and may vary depending on the installer's level of expertise, condition of the vehicle, and availability of proper tools and equipment.
The Curt 56562 is designed for passenger cars with 12-volt negative ground systems. Consult a fitment database or contact Curt Manufacturing with your vehicle's year, make, and model to confirm compatibility.
Use a test light, 4-way tester, or multimeter to verify the harness is functioning. Alternatively, connect the 4-way flat connector to a trailer with functioning lights. If the harness does not function, check that all wire connections are secure, the fuse is installed and not blown, the ground wire is properly connected to a clean metal surface on the vehicle frame, and the power wire is properly connected to the positive battery terminal with a ring terminal.
If the power wire passes through sheet metal, ensure it is protected by an existing grommet, a new grommet, or silicone to prevent damage from sharp edges. If damage occurs, the wire insulation must be repaired or the wire replaced before reconnecting the battery and fuse.
Ensure you are inserting the lighting modules connector carefully and not breaking the connector locking tabs. The connector should insert fully into the vehicle's taillight connector. If the connector does not fit, verify you are using the correct connector for the correct side (driver's or passenger's) and that the vehicle's taillight connector is not damaged.
