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 Taurus, Ford Explorer and Lincoln MKS (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.

On a Taurus, the taillight wiring harness connectors are located behind the felt trunk liner. Pull back the felt liner after removing the three plastic fasteners securing it with a panel trim removal tool. The connectors will be similar to those on the custom wiring harness. Separate them from the taillight housing carefully to avoid damaging the locking tabs.
On Explorer 10th generation models, the taillight housing is accessed by loosening the side wall panels with a panel trim removal tool, starting at the floor and working up to the headliner. Pull back the panel to locate the taillight housing and connectors. The connectors will be similar to those on the custom wiring harness. Separate them carefully to avoid damaging the locking tabs.
Insert the custom wiring end with the yellow wire between the separated taillight connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side with the green wire.
Drilling may be required for the ground wire connection. You must locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint before securing the white ground wire using the ring terminal and provided screw.
Drill a 3/32" pilot hole if a suitable existing grounding point is not available. The area should be free of rust, dirt and paint before installing the provided screw with the white ground wire ring terminal.
The wiring harness includes: Yellow wire (left turn signal), Green wire (right turn signal), Red wire (brake), Brown wire (taillight), White wire (ground), and Black wire (power). The yellow wire connects to the driver side taillight connector, and the green wire connects to the passenger side taillight connector.
