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 Ford Focus hatchback (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.

Curt part 56140 is a T-Connector wiring harness for Ford Focus Hatchback vehicles. It provides a connection point for trailer wiring by integrating with the vehicle's existing taillight wiring on both the driver and passenger sides.
You will need a drill with a 3/32" bit (if drilling a new grounding hole), a screwdriver, and basic hand tools. The manual does not specify whether a professional installer or additional equipment is required. Contact Curt technical support at 1-877-287-8634 if you are unsure about your ability to complete the installation.
Open the rear hatch and remove: all floor covers and foam trays in the rear cargo area, the rear scuff panel (held by 4 plastic fasteners), the felt liner behind the taillights, the plastic wing nuts holding the taillights, and the grommets on both sides of the vehicle. Take care not to damage the taillight alignment tabs when removing them.
You may need to drill one 3/32" hole if a suitable existing grounding point (such as an existing screw with nut in the vehicle's frame) is not available near the taillight connector. Before drilling, verify that miscellaneous items hidden behind or under surfaces will not be damaged.
If you need to drill a grounding hole, drill a 3/32" hole in the vehicle's frame near the taillight connector. Secure the white ground wire using the ring terminal and screw provided with the kit.
On the driver side, locate the vehicle's taillight wiring harness connector. Separate the connectors carefully without damaging the locking tabs. Insert the T-Connector end with the yellow wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the T-Connector end with the green wire.
The yellow wire connects to the driver side taillight wiring harness, and the green wire connects to the passenger side taillight wiring harness. These connections allow the trailer wiring to integrate with the vehicle's existing taillight circuits.
The white ground wire provides a ground connection for the T-Connector harness. Secure it to a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle's frame, using the ring terminal and screw provided.
Remove the grommet on both sides of the vehicle and make a small slit from the outside towards the center. Route the T-Connector end with the yellow wire through the opening made by the removed driver-side grommet. Route the T-Connector end with the green wire through the opening made by the removed passenger-side grommet. Replace each grommet, routing the wires through the slit made in the removal step.
The black power wire routes from the vehicle's battery to the converter box. The manual references the CME-PCL-INS instruction sheet for detailed routing and connection instructions. Review that sheet for the specific battery connection point and routing path.
Adhere the black converter box behind the felt trunk liner in the vehicle's rear cargo area using the double-sided tape provided with the kit.
When not in use, roll up the 4-flat wire and store it on the driver side in an out-of-the-way location in the rear cargo area. Route it out of the hatch only when the trailer is in use.
After completing all installation steps, reinstall all items that were removed during installation, including floor covers, foam trays, rear scuff panel, taillights, and grommets.
Before drilling, verify that miscellaneous items hidden behind or under any surface will not be damaged. Drilling into hidden components can cause damage and/or personal injury.
When removing the taillights, pull them out carefully and take care not to damage the alignment tabs. Damaged alignment tabs may prevent proper taillight reinstallation or function.
When separating the vehicle's taillight wiring harness connectors, take care not to damage the locking tabs. Damaged locking tabs may prevent proper connector seating and cause electrical issues.
