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 Jeep Cherokee (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.

Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
The battery connection must be fuse-protected with a 15-amp maximum fuse. Install the fuse after all other installation steps are complete. Exceeding this fuse rating can cause loss of warranty, overheating and potential fire.
The following tools are required: Ratchet, Utility knife, Socket 1/4", Wire crimper, Torx bit T-27, Wire stripper, Socket extension, and Fish wire.
Yes. Disconnect the negative battery terminal before beginning installation. Be sure to fasten this wire down and away from the battery when completing the installation process. Reconnect the negative battery terminal only after all other installation steps are complete.
Mount the converter box using the provided double-sided tape on a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Failure to mount the box in a protected area can cause loss of warranty, product failure, overheating and potential fire.
Route the black 12-gauge power wire from the vehicle battery to the converter, taking care to avoid any pinch points and hot or rotating components. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the power wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties.
You may use an existing screw with nut in the vehicle frame as a grounding point, or drill a 3/32" pilot hole for the provided screw if no suitable existing point is available. The area should be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The CURT 56406 uses the following wire colors: Yellow for left turn signal, Green for right turn signal, Red for brake, and Brown for taillight. The white wire is the ground wire. The black wire connects to the positive battery terminal.
Locate the vehicle taillight wiring harness connectors. Separate the 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. Then reinstall the taillight.
Secure the 4-flat to the center of the vehicle in a convenient, out-of-the-way location or to the rear hitch. Use the provided cable ties to secure any loose wires. Install the provided 4-flat dust cover to help prevent corrosion.
Once installed, test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the product will function properly.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections.
