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 (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 56368 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Subaru Impreza (Part #BKDK56368) is designed to fit the 2012-2016 Subaru Impreza.
The CURT 56368 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Subaru Impreza (Part #BKDK56368) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
Part 56368 fits Subaru Impreza hatchback models, excluding WRX and WRX STI variants. If your vehicle is a WRX or WRX STI, this harness is not compatible. Verify your exact model before purchasing.
The harness is rated for Signal Circuits at 3.0 amps per side and Tail/Running Circuits at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
You will need: ratchet, 10mm socket, Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire crimper, cutting tool, and side cutter. A 3/32" drill bit is also required for drilling the ground point if a suitable existing screw is not available.
The harness includes the custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for mounting the converter box, cable ties, sealant for the grommet, a 4-flat dust cover, and a CME-PCL-INS sheet with battery power wire routing instructions.
Yes. You must remove both the driver side and passenger side taillights by removing two 10mm fasteners on each side and gently pulling the taillight rearward and out. The custom harness is routed behind the taillights and inserted between the separated taillight connectors.
The harness end with the yellow wire is routed out through the grommet opening behind the driver side taillight. The harness end with the green wire is routed to the passenger side behind the removed scuff panel. Both ends are inserted between the separated taillight connectors. The 4-flat connector is routed to the center of the vehicle and out of the trunk when in use, then rolled up and stored inside the trunk when not in use.
Drilling may be required for the ground wire. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, you will need to drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt, and paint. You must also cut a slit in the grommet behind the taillight to route the custom wiring harness through.
Drill a 3/32" pilot hole for the provided ground screw. This is only necessary if a suitable existing screw with nut in the vehicle frame is not available. The area must be free of rust, dirt, and paint before securing the white ground wire with the ring terminal.
Remove two 10mm fasteners securing each taillight (driver and passenger side). Remove push fasteners securing the storage trays. Remove fasteners securing the rear scuff panel. The manual does not specify torque values for reinstallation; refer to your vehicle owner's manual for proper torque specifications when reinstalling these components.
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 your tow vehicle's lamp load rating, whichever is lower.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This is especially important when drilling the 3/32" pilot hole for the ground screw.
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 will function properly. The manual does not provide detailed testing procedures beyond this.
After routing the custom wiring harness through the grommet opening and inserting it between the separated connectors, reseat the grommet using the provided sealant to seal the cut in the grommet and around all the wires. This prevents water and debris from entering the vehicle.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The manual does not specify exact dimensions or clearance requirements for this location.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route it to the center of the vehicle and out of the trunk. Secure any loose wires with the provided cable ties.
Install the provided 4-flat dust cover to help prevent corrosion of the connector when not in use.
Yes, for standard Impreza hatchback models. It does not fit WRX or WRX STI variants.
