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 Mitsubishi RVR, Outlander Sport and Lancer (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.

The battery connection must be fuse-protected at 10-amp maximum. Signal circuits are rated at 3.0 amps per side, and tail/running circuits are rated at 6.0 amps total. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product 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. A 3/32" drill bit is also required to create a pilot hole for the ground wire screw (unless a suitable existing screw with nut is available in the vehicle frame).
The yellow wire end connects on the driver side. Insert it between the separated taillight connectors behind the driver side access panel, ensuring the connectors are fully inserted with locking tabs in place. Then reinstall the grommet and taillight.
The green wire end connects on the passenger side. Route it behind the removed scuff panel and repeat the connection steps on the passenger side, inserting it between the separated taillight connectors and ensuring the connectors are fully inserted with locking tabs in place.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, 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 the provided screw.
Drilling may be required. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, 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 any surface to avoid damage and personal injury.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
All steps must be followed to ensure the wiring harness functions properly. Once installed, test for proper function by using a test light or connecting a properly wired trailer. This confirms that all connections are secure and the harness is operating correctly.
The Curt 56127 includes the custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black converter box, a provided ground screw, double-sided tape for mounting the converter box, cable ties for securing loose wires, and a 4-flat dust cover. The manual also references an included CME-PCL-INS sheet for battery routing details.
Open the vehicle tailgate and remove the two Phillips screws securing each taillight assembly. Locate and remove the grommet behind each taillight where the vehicle taillight wiring passes through from inside the cabin to the taillight.
Inside the grommet hole, locate the vehicle taillight wiring harness connectors. They will be similar to those on the custom wiring harness. Separate the connectors from the taillight housing, taking care not to damage the locking tabs.
Remove the cargo area floor covering and the spare tire cover. Remove the two fasteners securing the rear scuff panel and pull it out at the bottom and then up, taking care not to damage the alignment tabs on the back. Remove the screws holding the rear trim panels in place and partially remove the driver and passenger side rear trim panels by pulling outward.
