The 16-22 Toyota Prius CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2413) fits the following vehicles: 2016-2022 Toyota Prius. Always verify your specific year, make, and model before ordering.
The 16-22 Toyota Prius CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2413) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, the Curt 56353 is designed for Toyota Prius passenger cars. The harness includes three connection points: behind the driver side taillight (P3), behind the passenger side taillight (P4), and behind the center of the rear bumper (P6).
The harness is rated for 3.0 amps per side on signal circuits and 6.0 amps total on tail/running circuits. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
You will need: ratchet, 10mm socket, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool. Sealant is included with the harness.
Yes. Step 1 requires you to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal before beginning installation.
Drilling may be required. Step 10 instructs you to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw if no existing point is available. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Yes. Step 13 requires you to locate the grommet behind the taillight where vehicle wiring passes through, remove it, and cut a slit large enough to route the custom wiring harnesses through. Step 15 requires you to reseat the grommet using the provided sealant to seal the cut and around all wires.
Installation follows this sequence: (1) disconnect the negative battery terminal; (2) remove trunk floor coverings, storage trays, and interior panels to access the driver side taillight connector; (3) separate the vehicle taillight connectors carefully without damaging locking tabs; (4) insert the custom harness end with the yellow wire between the separated connectors, ensuring full insertion with locking tabs in place; (5) repeat the process on the passenger side using the harness end with the green wire; (6) install the center rear bumper connector using the brown and red wire harness end; (7) reconnect the battery terminal and reinstall all removed items.
Step 10 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 point is available, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Step 16 instructs you to locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
Step 19 instructs that when in use, route the 4-flat 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.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
All installation 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.
Step 20 instructs you to install the provided 4-flat dust cover to help prevent corrosion.
