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 Crown Victoria, Ford Mustang and Mercury Grand Marquis (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 Curt 55326 is a custom wiring harness designed to connect your vehicle's taillight wiring to a 4-flat trailer connector. It allows you to safely tow a trailer by routing power from your vehicle's taillights through the harness to the trailer lights.
You will need a panel trim removal tool. This tool helps you safely remove the trunk scuff panel without damaging the alignment tabs. No other specialized tools are required for the basic installation.
Open the vehicle trunk. Remove the scuff panel by pulling out on the bottom and then up, taking care not to damage the alignment tabs on the back. Remove the plastic wing nuts securing the felt trunk liner. Pull back on the felt liner to locate the vehicle taillight wiring harness connectors behind the taillight housing.
Separate the vehicle taillight connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on both the driver and passenger sides.
Route the 4-flat connector to the center of the vehicle and out of the trunk when in use. When not in use, roll it up and store it in a convenient, out-of-the-way location inside the trunk.
Secure any loose wires with the provided cable ties. This helps prevent tangling, damage, and ensures a neat installation.
The harness includes cable ties for securing loose wires and a 4-flat dust cover to help prevent corrosion of the connector when not in use.
Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating, and potential fire. Consult your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating.
Test for proper function by using a test light or connecting a properly wired trailer. This confirms that the harness is correctly installed and all connections are secure before towing.
Yes. After routing and securing the wiring harness, reinstall all items removed during installation, including the felt trunk liner, plastic wing nuts, and scuff panel. Install the provided 4-flat dust cover to help prevent corrosion.
The harness has a yellow wire end and a green wire end. The yellow wire end connects to the driver side taillight housing (P3 location), and the green wire end connects to the passenger side taillight housing (P4 location).
