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 RAV4 (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.

You will need: a ratchet, 10mm socket, Phillips screwdriver, and a panel trim removal tool. The manual also recommends having a test light or properly wired trailer available to test the harness after installation.
The harness includes: a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black converter box, a provided screw for grounding, double-sided tape for the converter box, a 4-flat dust cover, and cable ties for securing loose wires.
Open the tailgate and remove: the rear scuff panel, trunk floor coverings, storage covers, and the privacy screen. Then remove all trim fasteners and slightly pull out the rear trim panels on both sides to access the taillight wiring harness connectors.
Separate the vehicle taillight connectors from the housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight. Adhere the black converter box using the provided double-sided tape. The converter box should be positioned where it will not interfere with vehicle operation.
When in use, route the 4-flat 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. If a suitable existing grounding point (such as a screw with nut in the vehicle frame) is not available near the taillight connector, you will need to drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for miscellaneous items hidden behind or under surfaces to avoid damage and personal injury.
Drill a 3/32" pilot hole for the provided ground screw. The area should be free of rust, dirt and paint before drilling.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or tow vehicle lamp load rating, whichever is lower.
Signal circuits are rated at 3.0 amps per side. Tail/Running circuits are rated at 6.0 amps total. Do not exceed these product ratings or the tow vehicle lamp load rating, whichever is lower.
The harness has a yellow wire end for the driver side connection, a green wire end for the passenger side connection, and a white ground wire with ring terminal. The black power wire connects to the vehicle battery (routing details are provided on the included CME-PCL-INS sheet).
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If one is not available, drill a 3/32" pilot hole for the provided screw. The area should be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. Ensure the grounding area is free of rust, dirt and paint.
Do not exceed the product rating (Signal circuits 3.0 amps per side, Tail/Running circuits 6.0 amps total) or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire. The battery connection must be fuse-protected with a 10-amp maximum fuse.
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 will function properly.
Reinstall all items removed during installation, including the rear scuff panel, trunk floor coverings, storage covers, privacy screen and rear trim panels. Install the provided 4-flat dust cover to help prevent corrosion.
