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 sedan (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 56138 Custom Wiring Harness is designed for Ford Focus sedans. The harness is installed behind the driver and passenger side taillight housings inside the trunk.
The 56138 has two circuit ratings: Signal Circuits are rated at 3.0 amps per side, and Tail/Running Circuits are rated at 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
The battery connection must be fuse-protected with a maximum 10-amp fuse. Exceeding this fuse rating can cause loss of warranty, overheating and potential fire.
You will need a Phillips screwdriver, flat blade screwdriver, and panel trim removal tool.
The manual does not specify whether the battery must be disconnected. Consult your vehicle owner's manual or the vehicle manufacturer for guidance on safe electrical work procedures.
Drilling may be required. Step 6 instructs you to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame, or drill a 3/32" pilot hole for the provided screw if no existing point is available. The area must be free of rust, dirt and paint before securing the white ground wire.
Drill a 3/32" pilot hole for the provided ground screw. The area should be free of rust, dirt and paint before installation.
Remove all trunk floor coverings, foam cargo trays surrounding the spare tire, and the rear scuff panel. On both sides of the trunk, remove the plastic fastener holding the plastic trim panel and the plastic fastener holding the felt trunk liner. Take care not to damage the alignment tabs on the back of the scuff panel.
Pull back the felt liner to locate the vehicle taillight wiring harness connectors. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. On the driver side, insert the custom wiring harness end with the yellow wire between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat on the passenger side using the harness end with the green wire.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
The 56138 uses colour-coded wires for different connections: yellow wire connects to the driver side taillight, green wire connects to the passenger side taillight, white wire is the ground wire, and black wire is the power wire from the vehicle battery. The harness also includes a black converter box.
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.
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 56138 includes the custom wiring harness with colour-coded wires (yellow, green, white, and black), a black converter box, a provided screw for the ground connection, double-sided tape for mounting the converter box, cable ties for securing loose wires, and a 4-flat dust cover to help prevent corrosion.
