If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Toyota Corolla sedan (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Yes, the Curt 55542 Custom Wiring Harness is designed for Toyota Corolla passenger cars. The manual confirms fitment for this model.
The Curt 55542 has a Signal Circuits rating of 3.0 amps per side and a Tail/Running Circuits rating of 5.0 amps total. Do not exceed these ratings or your tow vehicle's lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
You need a panel trim removal tool. The manual also indicates you may need to drill a 3/32" pilot hole for the grounding screw if a suitable existing screw is not available, so a drill with a 3/32" bit is recommended.
The harness includes a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black converter box, double-sided tape for mounting the converter box, a provided screw for grounding, and a 4-flat dust cover.
The harness connects behind the taillight housings inside the trunk. The yellow wire end connects to the driver side taillight (location P3) and the green wire end connects to the passenger side taillight (location P4). Each harness end inserts between the separated vehicle taillight connectors with locking tabs in place.
No. You remove the rear scuff panel and felt liner to access the taillight wiring connectors, but you do not need to remove the taillight housing itself. The custom harness end inserts between the separated connectors.
Drilling is not required if a suitable existing screw with nut is available in the vehicle frame near the taillight connector for grounding. If no existing screw is available, you must drill a 3/32" pilot hole for the provided grounding screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
If drilling is required, the pilot hole size is 3/32". The provided screw secures the white ground wire using a ring terminal.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. If no existing screw is available, drill a 3/32" pilot hole and use the provided screw.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The manual specifies this step twice, indicating it applies to both driver and passenger sides.
Route the 4-flat wire to the center of the vehicle and out of the trunk when in use. When not in use, roll it up and store it in an out-of-the-way location in the trunk.
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.
Exceeding the product rating (3.0 amps per side for signal circuits, 5.0 amps total for tail/running circuits) or your tow vehicle's lamp load rating, whichever is lower, can cause loss of warranty, overheating and potential fire. Do not exceed the product rating.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
1. Open trunk and remove rear scuff panel. 2. Remove felt liner fasteners on driver side. 3. Separate taillight connectors. 4. Insert yellow wire harness end between connectors. 5. Ground the white wire. 6. Route green wire to passenger side and repeat steps 2-4. 7-8. Mount converter box with double-sided tape near taillight. 9. Route 4-flat wire to trunk center when in use, store when not in use. 10. Reinstall removed items and install 4-flat dust cover.
The manual does not specify whether the battery must be disconnected. Consult your vehicle owner's manual or contact the vehicle manufacturer for guidance on electrical work safety.
The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
