The 20 - 23 Hyundai Sonata Excluding Hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK1447 (Part #7WK1447) fits 2020-2023 Hyundai Sonata models. The 2023 model year is the last year covered by this part number. For newer models, check for an updated version.
The 20 - 23 Hyundai Sonata Excluding Hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK1447 (Part #7WK1447) fits the following vehicles: 2020-2023 Hyundai Sonata. Always verify your specific year, make, and model before ordering.
Yes, the 20 - 23 Hyundai Sonata Excluding Hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK1447 (Part #7WK1447) is designed to fit the 2020-2023 Hyundai Sonata.
The 20 - 23 Hyundai Sonata Excluding Hybrid CURT Trailer Brake Controller 7-Way Upgrade Kit 7WK1447 (Part #7WK1447) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The kit includes: one 30 amp auto-resetting circuit breaker, two #10 ring terminals, two 3/8" ring terminals, two 1/2" ring terminals, three 12-10 gauge butt connectors, 10 feet of 10 ga black/white duplex wire, 20 feet of 10 ga blue cross-linked wire, and eight 8.5" cable ties.
Yes, but with a critical difference: these vehicles require the stop signal wire to be spliced to the light green wire on the turn signal harness connector under the dash, not to the brake pedal switch. Do NOT connect to the red wire with green stripe, as serious damage may occur. All other vehicles connect to the brake pedal switch instead.
You will need: a test light, wire stripper/cutter, crimp tool, and 3/8" box end wrench. The test light is used to identify the cold (switched) side of the brake pedal switch.
Yes. The manual cautions to disconnect the tow vehicle's negative battery cable before installation. Reconnect it only in the final step after all wiring is complete.
Mount the 30 amp circuit breaker near the tow vehicle's positive battery terminal. This keeps the power wire run as short as possible and protects the circuit.
Use 10 gauge (10 ga) black wire from the duplex wire included in the kit. Strip 3/8" of insulation from each end. Crimp a #10 ring terminal to the end that attaches to the circuit breaker stud labeled 'BAT', and a 3/8" or 1/2" ring terminal (sized to fit your battery terminal) to the end that attaches to the positive battery terminal.
Feed the 10 ga duplex wire from the brake controller in the cockpit through the firewall into the engine compartment toward the battery. Cut to length as needed. At the battery end, crimp a 3/8" or 1/2" ring terminal to the white wire and a #10 ring terminal to the black wire. Attach the black wire to the circuit breaker stud labeled 'AUX' and tighten the nut with a 3/8" box end wrench.
When passing the duplex wire through the firewall into the engine compartment, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to insulate and protect the wire. The same protection applies when passing the blue cross-linked wire through any sheet metal at the rear of the vehicle.
In the cockpit, attach the black duplex wire to the brake controller's battery wire (typically black) and the white duplex wire to the brake controller's ground wire (typically white). Use either one of the supplied yellow butt connectors or solder the leads together and insulate with heat shrink tubing.
Locate the brake pedal switch on the back side of the vehicle's brake pedal. Use a test light or volt meter to identify the 'cold' or switched side—this terminal will only show power when the brake pedal is depressed. Attach the stop signal wire (typically red) from the brake controller to the cold side of the switch using a wire tap.
Locate the semi-circle turn signal harness connector on the steering column under the dash. It has two rows of wires: a row of four and a row of seven. Attach the stop signal wire (typically red) from the brake controller to the light green wire using a wire tap. Do NOT connect to the red wire with green stripe, as serious damage may occur.
Feed the 10 ga blue cross-linked wire from the brake controller to the trailer connector at the rear of the vehicle, taking up any slack in the wire. When passing through any sheet metal, use an existing grommet, add a new grommet, or fill the hole with silicone rubber to protect the wire.
Attach the blue cross-linked wire to the brake controller's electric brake wire (typically blue) using one of the supplied yellow butt connectors or by soldering and insulating with heat shrink tubing. At the rear of the vehicle, trim any loose blue wire and attach it to the trailer connector's electric brake terminal. Refer to the trailer connector's wiring diagram for the correct terminal location.
Secure any loose wires with the cable ties provided. Connect the black power wire from the circuit breaker to the positive side of the battery. Connect the white ground wire from the brake controller to the negative side of the battery. Finally, reconnect the tow vehicle's negative battery cable to the battery.
The circuit breaker is 30 amps and auto-resetting. It must be mounted near the positive battery terminal and connected directly to the positive battery terminal via the included black 10 gauge wire.
Use a 3/8" box end wrench to tighten the nuts on the circuit breaker studs labeled 'BAT' and 'AUX'.
The kit includes 10 feet of 10 gauge black/white duplex wire for the battery and brake controller connections, and 20 feet of 10 gauge blue cross-linked wire for the electric brake signal to the trailer connector.
Black wire connects to the positive battery and circuit breaker. White wire connects to the brake controller ground and negative battery. Red wire is the stop signal wire from the brake controller. Blue wire is the electric brake signal wire. The manual notes these are 'typically' these colours but recommends confirming with your brake controller documentation.
Yes. You can solder the leads together and insulate with heat shrink tubing as an alternative to using the supplied yellow butt connectors. This applies to connections between the duplex wire and the brake controller wires, and between the blue cross-linked wire and the brake controller.
The black power wire must connect directly to the positive battery terminal via the 30 amp circuit breaker. Connecting to the fuse panel or any other accessory wiring may damage vehicle wiring and cause trailer brake failure. The circuit breaker protects the circuit and must be the only protection between the battery and the brake control system.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness. Serious damage may occur. Connect only to the light green wire. Also, do not connect to the brake pedal switch on these vehicles; use the turn signal harness instead.
The kit is universal but requires an existing trailer connector and brake controller. 1989-1991 Ford E & F-Series with ABS use a different stop signal connection (turn signal harness instead of brake pedal switch). Consult your brake controller documentation for compatibility.
No drilling is required. The kit connects to existing components: the battery, brake controller, brake pedal switch (or turn signal harness on 1989-1991 Ford E & F-Series with ABS), and trailer connector.
Do NOT connect the stop signal wire to the red wire with green stripe on the turn signal harness—serious damage may occur. Connect to the light green wire instead, and do not use the brake pedal switch.
Connecting to the fuse panel or accessory wiring may damage vehicle wiring and cause trailer brake failure. The 30 amp circuit breaker must be the only protection between the battery and the brake control system.
The Curt 56461 is a powered converter lead designed to convert vehicle taillight signals for trailer use. It interfaces with your vehicle's existing taillight wiring connectors and provides converted signals (left turn, right turn, brake, and taillight) through a 4-flat connector for trailer connection. The system includes a black converter box that mounts inside the trunk and routes power from the vehicle battery.
The Curt 56461 is designed for passenger cars with 12-volt negative ground electrical systems. The manual states it is for use on passenger cars and shows wiring locations P1 through P7 for typical passenger car taillight and bumper areas. For specific vehicle compatibility, consult the vehicle owner's manual or contact the vehicle manufacturer.
No. The manual explicitly states: 'This converter system is to be used only on 12 volt negative ground systems.' Do not install on positive ground vehicles.
The following tools are required: panel trim removal tool, cutting tool, large flathead screwdriver, wire crimper, wire stripper, and electrical tape. The manual notes that proper tools will improve the quality of installation and reduce the time required.
The kit includes: a black converter box, yellow wire connector for driver side taillight, green wire connector for passenger side taillight, white ground wire with ring terminal, black power wire, provided double-sided tape for mounting the converter box, cable ties for securing wires, a ground screw, a 4-flat dust cover, and a fuse holder with 10-amp fuse (to be installed after all other steps are complete).
Yes. Step 1 requires you to locate the vehicle's battery in the engine compartment on the driver side and disconnect the negative battery terminal. Fasten this wire down and away from the battery while completing the installation. The battery must remain disconnected until Step 9, when you reconnect the negative terminal after all wiring is complete.
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 proper tools and equipment.
Follow these steps in order: (1) Disconnect the negative battery terminal and secure it away from the battery. (2) Open the trunk and remove the floor covering to expose the spare tire. (3) Remove the two fasteners in the trunk threshold using a flathead screwdriver. (4) Loosen push fasteners in the trunk threshold and lift off the threaded bolt. (5) Loosen push fasteners in the side wall (two on each side) and pull back the felt liner to expose the taillight electrical harness. (6) Separate the driver side taillight connectors and insert the yellow wire connector between them. (7) Mount the black converter box inside the trunk using double-sided tape and secure the white ground wire to a grounding point. (8) Route the green wire to the passenger side and connect it to the passenger side taillight connectors. (9) Route the black power wire from the vehicle battery. (10) Reinstall all removed items and reconnect the negative battery terminal. (11) Install the 4-flat dust cover and test the system.
The converter connects to the vehicle's existing taillight wiring connectors at two locations: (1) Driver side (P3): Pull back the sidewall panels to locate the taillight wiring connectors. Separate the connectors from the taillight housing carefully without damaging the locking tabs. Insert the custom wiring end with the yellow wire between the separated connectors, ensuring they are fully inserted with locking tabs in place. (2) Passenger side (P4): Route the green wire along the back of the trunk below the threshold to the passenger side. Locate the taillight wiring connectors, separate them, and insert the custom wiring end with the green wire between them, ensuring full insertion with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The area should be clean and flat to ensure proper adhesion.
Locate a grounding point near the converter box, such as an existing screw or bolt in the vehicle frame. If no suitable point exists, 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. Secure the white ground wire with its ring terminal to the existing fastener or use the provided ground screw. The manual cautions to check for miscellaneous items hidden behind or under any surface before drilling to avoid damage and personal injury.
When in use, route the 4-flat connector 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.
Drilling may be required only if no suitable existing grounding point is available near the converter box location. If drilling is necessary, you must drill a 3/32-inch pilot hole for the 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. The area must be cleaned of rust, dirt, and paint using an abrasive pad or paper.
The converter uses the following wire colors: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight (running lights). The yellow and green wires connect to the vehicle's taillight connectors at the driver and passenger sides respectively. The red brake wire must be grounded if the converter is used as a powered module for a two-wire system. The black power wire connects to the vehicle battery positive terminal.
Route the 12 GA (or larger) black power wire from the converter to the vehicle battery location, taking care to avoid pinch points and hot or rotating components. Connect the ring terminal of the black power wire to the vehicle battery positive (+) terminal. 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.
The battery connection must be fuse-protected with a maximum 10-amp fuse. A fuse holder with a 10-amp fuse is provided. Install the fuse after all other installation steps are complete. Exceeding the 10-amp maximum can cause loss of warranty, overheating, and potential fire.
Signal circuits (left and 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. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Follow these safety precautions: (1) Disconnect the negative battery terminal before wiring the power wire and keep it secured away from the battery during installation. (2) Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. (3) When routing the black power wire, avoid pinch points and hot or rotating components. (4) 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. (5) Do not exceed the product rating (3.0 amps per signal circuit, 6.0 amps total for tail/running circuits) or the tow vehicle lamp load rating, whichever is lower. (6) Ensure the battery connection is fuse-protected with a maximum 10-amp fuse.
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. The manual states: 'Once 12 volt power wire is connected 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.'
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. This helps maintain proper function and prevent electrical issues.
The Curt 56461 is designed for passenger cars with 12-volt negative ground electrical systems. Verify your vehicle has a negative ground system and consult your vehicle owner's manual or contact the manufacturer for specific model compatibility.
You will need: panel trim removal tool, cutting tool, large flathead screwdriver, wire crimper, wire stripper, and electrical tape.
Yes. You must disconnect the negative battery terminal before beginning installation and keep it secured away from the battery. Reconnect it only after all wiring is complete.
The battery connection must use a 10-amp maximum fuse. Install the fuse after all other steps are complete. Exceeding 10 amps can cause warranty loss, overheating, and fire.
Signal circuits: 3.0 amps per side. Tail/Running circuits: 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower.
Verify the following: (1) Ensure the negative battery terminal is properly reconnected. (2) Check that the 10-amp fuse is installed in the fuse holder and is not blown. (3) Verify that the yellow and green wire connectors are fully inserted into the vehicle's taillight connectors with locking tabs securely in place. (4) Check that the white ground wire is properly secured to a clean grounding point free from rust, dirt, and paint. (5) Ensure the black power wire is properly connected to the vehicle battery positive terminal with a ring terminal. (6) Test the system using a test light, 4-flat tester, or functioning trailer. If the system still does not function, consult the vehicle manufacturer or a qualified technician.
The converter box is mounted using the provided double-sided tape on a flat spot inside the vehicle near the taillight. If the tape is not holding: (1) Ensure the mounting surface is clean, dry, and free from dust or debris. (2) Press the converter box firmly onto the surface for several seconds to ensure good adhesion. (3) If the tape fails to hold, consider using an alternative mounting method such as a small bracket or additional adhesive, provided it does not interfere with vehicle operation or safety.
The 4-way flat electrical adapter converts a vehicle's 4-way flat trailer connector to other trailer connector types (6-way round, 7-way RV blade, or dual 4-way flat). This allows you to tow trailers with different connector styles. Single-output models (57184, 57183, 57185, 57626, 57676) convert to one connector type; dual-output models (57604, 57624, 57672, 57674, 57102) provide two different connector outputs simultaneously.
Yes. Your vehicle must be equipped with a 4-way flat trailer connector. If your vehicle does not have one, you will need to install a custom wiring harness or other 4-way flat trailer connector before installing this adapter.
Both convert a 4-way flat connector to a 7-way RV blade. The difference is that 57185 includes a mounting bracket, while 57184 does not.
Both convert a 4-way flat connector to a 6-way round. The difference is that 57626 includes a mounting bracket, while 57183 does not.
Curt offers three dual-output models that provide both a 4-way flat and a 7-way RV blade output: part numbers 57672, 57674, and 57102. All three include a mounting bracket.
Curt offers two dual-output models that provide both a 4-way flat and a 6-way round output: part numbers 57604 and 57624. Both include a mounting bracket.
You will need: a 1/8" drill bit, drill, Phillips screwdriver, wire stripper, cutting tool, terminal crimpers, and a test light. The manual also lists three self-tapping screws (#10 - 1/2") as required, though these are not included with the product.
No. The three self-tapping screws (#10 - 1/2") used to attach the mounting bracket are not included and must be purchased separately.
Mount the combination harness in a location on the tow vehicle that is within reach of the trailer's wiring harness and near the center of the vehicle. The mounting bracket (if included) should be attached to the vehicle's bumper or other suitable surface.
Yes. You must drill two 1/8" holes: one for the grounding point and one (or more) for the mounting bracket. Before drilling, you must check for brake lines, fuel lines, wiring and other components that may be hidden behind or under the surface to avoid damage.
No. You must never attach the mounting bracket directly to the hitch by cutting, welding or drilling into the hitch. Mount it to the vehicle's bumper or other suitable surface instead.
The adapter uses four wires: Yellow (auxiliary or back-up lights), Blue (electric brakes), Black (positive power with appropriate inline fuse), and White (ground). All wires except black and white must be connected using 12 gauge (minimum) wire and butt connectors to the appropriate vehicle functions.
The white wire is the ground connection. It must be attached with a ring terminal to a 1/8" hole drilled in a suitable grounding point on the vehicle using a #10 - 1/2" self-tapping screw. This ground connection is required for the harness to work properly. The white wire on the vehicle's 4-way flat connector does not support the ground (-) functions of the combination harness.
Yes. The black wire (positive power) must be connected with an appropriate inline fuse. The manual does not specify the fuse amperage rating.
Use 12 gauge (minimum) wire for all connections. The manual specifies this minimum gauge for the remaining wires (yellow, blue, and black) when connecting to appropriate vehicle functions.
Failing to properly ground the product can cause loss of warranty, overheating and potential fire. The white wire must be securely attached to a clean grounding point using a #10 - 1/2" self-tapping screw in a 1/8" hole. The area must be clean of dirt, debris or undercoating.
Before drilling, you must check for brake lines, fuel lines, wiring and any other components that may be hidden behind or under the surface. Drilling into these components can cause damage and personal injury.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding either rating can cause damage or unsafe operation.
Confirm proper function with a test light or by using a properly functioning trailer. This verifies that all connections are working correctly before towing.
Secure any loose wires using cable ties or equivalent product to prevent them from moving, catching on components, or becoming damaged.
Your vehicle must have a 4-way flat trailer connector. If it does not, you will need to install a custom wiring harness or other 4-way flat connector first. Check the part number table to confirm the adapter converts to the connector type you need.
You must purchase three #10 - 1/2" self-tapping screws for the mounting bracket. You will also need an appropriate inline fuse for the black (positive power) wire; the manual does not specify the amperage.
Yes, you must drill two 1/8" holes: one for grounding and one for the mounting bracket. Before drilling, check for brake lines, fuel lines and wiring behind the surface. Never drill into the hitch.
Yellow = auxiliary/back-up lights; Blue = electric brakes; Black = positive power (needs inline fuse); White = ground (must be properly grounded or warranty is void and fire risk exists). Use 12 gauge minimum wire and butt connectors.
Proper grounding of the white wire is critical. Failing to ground it properly can cause loss of warranty, overheating and fire. The grounding point must be clean of dirt, debris and undercoating.
Test with a test light or by using a properly functioning trailer to confirm all connections work. Secure loose wires with cable ties.
