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 setup. 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 vehicle's electrical system and provides a standard 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 harness provides a 7-way RV blade connector socket and is designed to be a custom wiring harness for certain years of the Ford Explorer and Police Interceptor Utility (see application info to verify fitment). 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.

Yes, the Curt 56306 is designed for Ford Explorer and other SUVs, mini and full-sized vans in the S-series category. The connector mounts behind the passenger side rear bumper (location S7) and interfaces with the black vehicle tow plug located behind the rear tire along the frame rail.
The Curt 56306 is a custom wiring connector that interfaces between your vehicle's factory tow plug and a 7-way trailer connector. It provides connections for stop/turn lights, taillights, backup lights, battery power, trailer brakes, and reverse lights, allowing you to safely tow a trailer with proper lighting and brake control.
The Curt 56306 has seven color-coded wires: White (1) is ground, Blue (2) is trailer brake, Brown (3) is tail and running light, Black (4) is battery positive, Yellow (5) is left turn and brake, Green (6) is right turn and brake, and Red (7) is reverse lights. Each wire connects to a specific terminal on the 7-way connector.
The Curt 56306 has the following amperage ratings: Stop/Turn Light – 10 amps, Taillights – 10 amps, Backup – 10 amps, Power Circuit – 30 amps, and Trailer Brakes (3 Axles/6 Brakes) – 20 amps. 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.
Yes, you must disconnect the negative battery terminal before beginning installation. This is the first step in the installation process and is required for safety.
The black vehicle tow plug is located behind the rear tire along the frame rail. You will separate the connectors on this plug and insert the custom wiring connector between them.
Locate the black vehicle tow plug behind the rear tire along the frame rail. Carefully separate the connectors, taking care not to damage the locking tabs. Insert the custom wiring connector between the separated tow plug connectors, ensuring the connectors are fully inserted with locking tabs in place.
Route the seven-wire end of the custom connector along the inside of the bumper toward the center of the vehicle to the 7-way mounting location. Secure any loose wires with the provided cable ties to prevent movement and damage.
The manual does not specify any tools needed for installation. The installation process involves disconnecting the battery terminal, separating and reconnecting connectors, and routing wires with provided cable ties.
After installation is complete, test and verify the product by one of these methods: if your vehicle is equipped with a brake controller, use a properly wired trailer or a brake system tester; if not equipped with a brake controller, use a properly wired trailer or test lamps. For the initial test, reset the electrical system by temporarily removing the vehicle key from the ignition. Note that the battery positive output may not be active until the vehicle is started and the brake is depressed with the trailer connected.
The manual does not specify a maximum towing load rating. It only provides amperage ratings for individual circuits and warns not to exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Consult your vehicle owner's manual or contact the vehicle manufacturer for towing capacity information.
