Yes, the 19-22 Toyota Avalon CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2354) is designed to fit the 2019-2022 Toyota Avalon.
The 19-22 Toyota Avalon CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2354) fits 2019-2022 Toyota Avalon models. The 2022 model year is the last year covered by this part number. For newer models, check for an updated version.
The 19-22 Toyota Avalon CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2354) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The CURT 56416 is designed for passenger cars with 12-volt negative ground electrical systems. Check your vehicle owner's manual to confirm it has a 12-volt negative ground system. The product is not compatible with 24-volt systems or positive ground systems. If you are unsure, contact the vehicle manufacturer or CURT customer support with your vehicle's year, make, and model.
The CURT 56416 is a powered converter wiring harness that converts vehicle taillight signals to a 4-flat trailer connector. It includes a converter box that processes left turn (yellow wire), right turn (green wire), brake (red wire), and taillight (brown wire) signals from your vehicle's taillights and outputs them to a standard 4-flat connector for towing.
You will need: ratchet, cutting tool, 10 mm socket, electrical tape, wire crimper, panel trim removal tool, and wire stripper. These tools are required to disconnect the battery, remove interior trim panels, access wiring connectors, and prepare and connect the wiring harness.
The kit includes: a converter box with wiring harness (yellow, green, red, and brown wires), a black power wire with ring terminal, a white ground wire with ring terminal, double-sided tape for mounting the converter, cable ties for securing wires, a 4-flat dust cover, a fuse holder with 10-amp fuse, a screw for the ground connection, and butt connectors. The 4-flat connector itself is part of the harness.
Yes. Step 1 requires you to disconnect the negative battery terminal before beginning installation. Fasten the disconnected wire down and away from the battery. Reconnect it only after all other installation steps are complete and you have verified the harness is functioning.
Open the trunk and remove all trunk floor coverings to expose the spare tire. You will also need to remove the rear scuff panel using a panel trim removal tool to access the taillight wiring connectors on both sides. Take care not to damage the alignment tabs on the back of the scuff panel when removing it.
Locate the taillight wiring connectors behind each taillight housing (driver side first, then passenger side). Separate the connectors from the taillight housing carefully without damaging the locking tabs. Insert the custom wiring harness end with the yellow wire (driver side) or green wire (passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place. Repeat on the passenger side.
Locate a flat, clean, protected surface behind the trunk liner and adhere the black converter box using the provided double-sided tape. Mounting the box in a protected area is critical—failure to do so can cause loss of warranty, product failure, overheating, and potential fire. The box must be kept away from moisture, heat sources, and physical damage.
Between the driver-side taillight housing and the side wall is a factory ground bolt. Use a 10 mm socket to loosen this bolt. Attach the ring terminal of the white ground wire from the converter box to this bolt and re-install the bolt. Ensure that factory grounds have not fallen off the bolt during this process.
Use 12 GA wire or larger for the power lead from the vehicle battery to the converter. Route the black power wire from the vehicle battery as shown in the manual, taking care 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.
Yellow wire = Left turn signal; Green wire = Right turn signal; Red wire = Brake signal; Brown wire = Taillight (running lights). These wires connect to the vehicle's taillight connectors. The converter processes these signals and outputs them to the 4-flat trailer connector.
The battery connection must be fuse-protected with a 10-amp maximum fuse. A fuse holder with a 10-amp fuse is included in the kit. Install the fuse after all other installation steps are complete. Exceeding the 10-amp rating 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 these ratings can cause loss of warranty, overheating, and potential fire.
When in use, route the 4-flat connector to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties. Install the provided 4-flat dust cover to help prevent corrosion.
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 that all steps must be followed to ensure the product functions properly. Once installed, test for proper function before using the converter with a trailer.
Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Check the 4-flat dust cover regularly to ensure it is in place and protecting the connector from corrosion. Secure any loose wires with cable ties as needed.
The installation is rated as Easy. However, you must follow all steps carefully, use proper tools, and ensure the converter box is mounted in a protected area. The manual recommends reading all instructions thoroughly before beginning and notes that proper tools will improve the quality of installation and reduce the time required.
Before drilling any holes, check for miscellaneous items that may be behind or under any surface to avoid personal injury or property damage. Route the 12 GA power wire to the vehicle battery location, taking care 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. Disconnect the negative battery terminal before wiring the power wire.
The CURT 56416 is designed for passenger cars with 12-volt negative ground electrical systems. Verify your vehicle has a 12-volt negative ground system in the owner's manual. Contact CURT or the vehicle manufacturer if you are unsure.
Yes. Disconnect the negative battery terminal before beginning installation and reconnect it only after all other steps are complete and the harness has been tested.
A 10-amp maximum fuse is required. The fuse holder and 10-amp fuse are included. Install the fuse after all other installation steps are complete.
Use 12 GA wire or larger for the power lead from the vehicle battery to the converter. Route it to avoid pinch points and hot or rotating components.
Mount the converter box on a flat, clean, protected surface behind the trunk liner using the provided double-sided tape. A protected location is critical to prevent warranty loss, product failure, overheating, and fire.
