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 Mustang (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.

Part 56088 is a Curt Manufacturing T-connector trailer wiring harness system designed for Ford Mustang vehicles. It provides a connection point for trailer lighting by tapping into the vehicle's existing taillight wiring. The system includes a T-connector with colour-coded wires (yellow and green for each side), a black converter box, and a white ground wire.
Yes, part 56088 is designed specifically for Ford Mustang vehicles. The manual does not specify model years or generations, so contact Curt Manufacturing or your retailer to confirm fitment for your specific Mustang year and generation.
The kit includes a T-connector with yellow and green wire ends, a black converter box, a white ground wire with eyelet and screw, double-sided tape, and cable ties. You will need a screwdriver and a 3/32" drill bit (if drilling a ground hole). A separate CME-PCL-INS instruction sheet is included for battery power routing.
The manual does not explicitly state whether the battery must be disconnected. However, because the installation involves working with the vehicle's taillight wiring and routing a power wire from the battery, it is strongly recommended to disconnect the negative battery terminal before beginning work. Refer to your vehicle's owner manual or consult a professional installer if you are unsure.
Open the trunk and remove the rear scuff panel by removing two plastic fasteners and two plastic wing nuts holding it in place. This will expose the taillight wiring harness on the driver's side.
On the driver's side, locate the vehicle's taillight wiring harness. Carefully separate the connectors without damaging the locking tabs. Insert the T-connector end with the yellow wire between the separated connectors, ensuring the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the green wire end of the T-connector.
After connecting the yellow wire end to the driver's side taillight connector, route the green wire end to the passenger side behind the removed scuff panel and connect it to the passenger-side taillight connector using the same method. Secure any loose parts of the T-connector with the cable ties provided.
Drilling is optional. The installation requires a ground wire connection. You may locate an existing screw with nut in the vehicle's frame to use as a grounding point, or you may drill a 3/32" hole and secure the white ground wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
If you choose to drill a ground hole, drill a 3/32" hole. Secure the white ground wire using the eyelet and screw provided in the kit. Before drilling, verify that no miscellaneous items are hidden behind or under the surface to avoid damage and personal injury.
Adhere the black converter box to the frame of the car using the double-sided tape provided in the kit. Ensure it is positioned securely and in a location where it will not be damaged or interfere with vehicle operation.
Route the black power wire from the battery to the black converter box as shown on the CME-PCL-INS sheet included with the kit. Route the black wire through any rubber grommet in the trunk area if applicable. The CME-PCL-INS sheet provides detailed instructions for this connection.
Before drilling, verify that miscellaneous items are not hidden behind or under any surface where you plan to drill. This is critical to avoid damage to vehicle components and personal injury.
The T-connector has a yellow wire and a green wire. The yellow wire connects to the driver's side taillight wiring, and the green wire connects to the passenger side taillight wiring. The connector also includes a white ground wire.
