Yes, the 01-07 Toyota Highlander CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2398) is designed to fit the 2001-2007 Toyota Highlander.
The 01-07 Toyota Highlander CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2398) fits the following vehicles: 2001-2007 Toyota Highlander. Always verify your specific year, make, and model before ordering.
The 01-07 Toyota Highlander CURT 4-flat Plug and Play Trailer Wiring (Part #CTW2398) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The Curt 55400 Custom Wiring Harness is designed for Hyundai Azera and Toyota Highlander (excluding Hybrid models). If you have a Highlander Hybrid or a different vehicle, this harness is not compatible. Check your vehicle's make, model, and year against these applications before purchasing.
The Curt 55400 has two amperage ratings: signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. You must not exceed these product ratings or your tow vehicle's lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating, and potential fire.
You will need a Phillips screwdriver, a flat blade screwdriver, and a panel trim removal tool. The manual also indicates you may need to drill a 3/32" pilot hole for the ground wire screw, so a drill with a 3/32" bit is recommended.
The manual does not explicitly state whether the battery must be disconnected before installation. For safety, consult your vehicle owner's manual or contact the vehicle manufacturer before beginning work on electrical systems.
Drilling may be required. In Step 5, you must locate a suitable grounding point near the taillight connector. If an existing screw with nut is not available in the vehicle frame, you will need to drill a 3/32" pilot hole for the provided ground screw. The area must be free of rust, dirt, and paint before securing the white ground wire.
Drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Open the trunk and remove the threshold. Pull back on the felt liner to locate the vehicle taillight wiring harness connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs.
Open the hatch and remove the floor cover panels and trays. Remove the access panel to locate the vehicle taillight wiring harness connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs.
The custom wiring harness has two ends: one with a yellow wire and one with a green wire. Insert the yellow wire end between the separated connectors at the driver side taillight (P3 location). Route the green wire end to the passenger side (P4 location) and repeat the connection process.
Insert the custom wiring harness end (yellow wire first) between the separated vehicle taillight connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process for the green wire end at the passenger side taillight.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If one is not available, drill a 3/32" pilot hole. The area must be free of rust, dirt, and paint. Secure the white ground wire using the ring terminal and provided screw.
Route the black power wire from the vehicle battery as shown on the included CME-PCL-INS sheet. If applicable, route the black wire through any rubber grommet in the trunk area to the black converter box. The manual does not provide detailed routing instructions on the pages supplied; refer to the CME-PCL-INS sheet included with your harness.
Locate a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. 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.
Secure any loose parts of the harness with the provided cable ties. This helps prevent damage and ensures the harness remains in place during vehicle operation.
The provided 4-flat dust cover helps prevent corrosion. Install it after completing all other installation steps.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this fuse rating can cause loss of warranty, overheating, and potential fire. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
