The Curt 56457 is a powered converter that enables trailer lighting on passenger cars. It converts the vehicle's taillight signals (left turn, right turn, brake, and tail lights) into a 4-flat trailer connector. The converter includes a black converter box that mounts inside the trunk and a powered lead that connects to the vehicle battery for operation.
The Curt 56457 is designed for passenger cars with 12-volt negative ground electrical systems. The manual does not specify which makes, models, or years are compatible. Contact Curt Manufacturing or consult a fitment database to confirm compatibility with your specific vehicle before purchasing.
No. The converter system is designed only for 12-volt negative ground systems. It cannot be used on 24-volt systems or vehicles with positive ground electrical systems.
Required tools are: panel trim removal tool, wire crimper, flathead screwdriver, wire stripper, cutting tool, paint marker, rag/towel, and electrical tape. The manual notes that proper tools will improve installation quality and reduce time required.
The kit includes: a black converter box, a powered lead with 12-gauge wire, cable ties, double-sided tape, sealant for the grommet, a ring terminal for the ground wire, a screw for the ground connection, a 10-amp fuse holder with fuse, a 4-flat dust cover, and butt connectors. The custom wiring harness with red, brown, yellow, and green wires is also included.
Yes. Step 1 requires you to locate the vehicle's battery in the engine compartment and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation. The power wire must not be connected to the battery until all other steps are complete and the system has been tested.
The manual rates the installation difficulty as Easy. However, the manual notes that 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 black converter box mounts on the driver side of the trunk, on a flat spot behind the trunk liner. It is adhered using the provided double-sided tape (Step 11). The manual does not specify exact dimensions or clearances for this location.
The installation involves three separate connections: (1) Insert the custom wiring harness end with red and brown wires between the separated driver-side taillight connectors (Step 4); (2) Insert the custom wiring end with brown and red wires through the grommet opening on the driver side (Step 6); (3) Insert the yellow wire to the driver-side turn signal (Step 9); (4) Insert the green wire to the passenger-side turn signal (Step 10). For each connection, separate the connectors from the taillight housing carefully without damaging the locking tabs, insert the custom wiring end, and ensure the connectors are fully inserted with locking tabs in place.
In Step 5, run the green and yellow wires along the back of the vehicle to the center of the trunk. Remove the grommet in the lower rear of the trunk pan and route the wires through the hole. Secure the wires with zip ties as needed behind the trunk skid plate. In Step 8, locate the harness from the grommet hole in the trunk pan and route the yellow wire to the driver-side turn signal, securing loose wires with provided cable ties. Repeat this process with the green wire to the passenger-side turn signal (Step 10).
After routing the custom wiring through the grommet opening in Step 6, you must use the provided sealant to seal the cut in the grommet and around all the wires. This prevents water and debris from entering the vehicle through the grommet hole.
Route the 12-gauge black power wire from the vehicle battery to the converter, taking care to avoid pinch points and hot or rotating components. Use existing grommets or add new ones to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties. Use a ring terminal for the battery connection. Install the 10-amp fuse holder with fuse after all other steps are complete. Do not connect the power wire until the system has been tested with a test light, 4-flat tester, or functioning trailer.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
Drilling may be required for the ground wire connection. The white ground wire ring terminal attaches to the vehicle body using a provided screw. If a suitable existing hole is not available, you must drill a 3/32-inch hole. The manual also warns to check for miscellaneous items behind or under any surface before drilling to avoid personal injury or property damage.
Yes. In Step 6, you must locate the grommet behind the taillight where the vehicle's taillight wiring passes from inside the cabin to the taillight. Remove the grommet and cut a slit large enough to route the new custom wiring end through. After routing the wires, reseat the grommet and use the provided sealant to seal the cut in the grommet and around all the wires.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
The battery connection must be fuse-protected with a 10-amp maximum fuse. The kit includes a fuse holder with a 10-amp fuse. Install the fuse after all other installation steps are complete. Exceeding this rating can cause loss of warranty, overheating, and potential fire.
The power lead uses 12-gauge wire or larger. This wire routes from the vehicle battery to the converter system and must be protected from sharp edges using existing grommets, new grommets, or silicone.
The white ground wire ring terminal attaches to the vehicle body using a provided screw. If a suitable existing hole is not available, drill a 3/32-inch hole.
The custom wiring harness uses the following color code: Green = Right turn signal, Red = Brake, Yellow = Left turn signal, Brown = Tail light. These wires connect to the corresponding vehicle taillight circuits and the 4-flat trailer connector.
The manual identifies seven wiring locations for passenger cars: P1 (behind driver side taillight housing, outside of trunk), P2 (behind passenger side taillight housing, outside of trunk), P3 (behind driver side taillight housing, inside of trunk), P4 (behind passenger side taillight housing, inside of trunk), P5 (behind driver side rear bumper), P6 (behind center of rear bumper), and P7 (behind passenger side rear bumper). The installation uses locations P3, P5, and P7.
The manual does not specify a tow load rating. It states only that you must not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Consult the vehicle owner's manual or contact the vehicle manufacturer for tow rating information.
Route the 12-gauge power wire to avoid pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties. Disconnect the negative battery before wiring the power wire.
After connecting the 12-volt power wire to the harness, verify that the harness is functioning by attaching the battery and testing with a test light, 4-flat tester, or a functioning trailer. Do not install the fuse until all other steps are complete and the system has been tested.
Reinstall all items removed during installation. If the negative battery terminal was disconnected at the beginning, reconnect it. Install the provided 4-flat dust cover to help prevent corrosion. Perform a functional test using a test light, 4-flat tester, or functioning trailer before towing.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. The manual does not specify an inspection interval. Install the provided 4-flat dust cover to help prevent corrosion when the connector is not in use.
The battery connection must use a 10-amp maximum fuse. The kit includes a 10-amp fuse holder. Install the fuse after all other steps are complete.
Green = Right turn, Red = Brake, Yellow = Left turn, Brown = Tail light. The power lead uses 12-gauge black wire to the battery and white wire for ground.
