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 Subaru Impreza, Subaru BRZ and Scion FRS (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, you must disconnect the negative battery terminal before beginning installation. The battery is located on the passenger's side under the hood. Reconnect it only after all other installation steps are complete.
You must remove: all trunk floor coverings, three plastic push fasteners and the rear scuff panel, and three plastic push fasteners on each side of the trunk that hold the felt trunk liner in place. These removals provide access to the taillight wiring harness connectors.
The vehicle's wiring harness connectors are located in the trunk behind the taillight in positions P3 and P4, as shown in the Wiring Location Guide included with the kit. You will access them after removing the trunk floor coverings, scuff panel, and felt trunk liner.
Separate the vehicle's taillight wiring harness connectors by carefully pulling them apart, taking care not to damage the locking tabs. Insert the T-Connector end with the green wire between the separated connectors on the passenger's side, ensuring the connectors are fully inserted with locking tabs in place. Repeat this process on the driver's side using the T-Connector end with the yellow wire.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle's frame. The area must be free of rust, dirt, or paint. If no suitable point exists, drill a 3/32" pilot hole. Secure the white ground wire using the ring terminal and screw provided with the kit.
Drilling may be required. If a suitable existing grounding point (such as a screw with nut in the vehicle's frame) is not available, you must drill a 3/32" pilot hole for the provided grounding screw. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
