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 Chrysler Town and Country, Dodge Caliber, Durango and Grand Caravan and Jeep Patriot (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 Custom Wiring, 4-Flat, Select Town and Country, Durango, Grand Caravan, Patriot Trailer Connector Kit (Part #BKDK56333) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The CURT 56333 is a powered converter lead designed to integrate trailer wiring with your vehicle's existing taillight system. It connects to your vehicle's taillight wiring harness and battery to provide signal and power circuits for trailer lighting. The converter uses a 4-flat connector for the trailer side and includes a black converter box that mounts inside the vehicle near the taillight.
Yes, the CURT 56333 is designed for the Dodge Patriot. Installation involves removing two clips holding the taillights in place, carefully prying the taillight housing rearward, and connecting the custom wiring harness to the vehicle's taillight connectors. Take care not to break the locking tabs on the back of the housing.
Yes, the CURT 56333 is designed for the Dodge Caravan, Grand Caravan, and Town & Country.

Yes, the CURT 56333 is designed exclusively for 12-volt negative ground systems. The manual states: 'This converter system is to be used only on 12 volt negative ground systems.' If your vehicle uses a different electrical system configuration, this product is not compatible.
You will need: a ratchet, a panel trim removal tool, and a Torx bit (T-30). The T-30 bit is required only if you are installing on a Caravan, Grand Caravan, or Town & Country, which use T-30 torx head screws to hold the taillights in place. The Patriot, Caliber, and Durango use clips instead.
The kit includes: a custom wiring harness with yellow and green wire ends, a black converter box, a white ground wire with ring terminal, a provided screw for grounding, double-sided tape for mounting the converter box, cable ties for securing loose wires, a 4-flat dust cover, and a 10-amp fuse holder with fuse. The manual also references a CME-PCL-INS instruction sheet for battery routing details.
Yes, you must disconnect the negative battery terminal before beginning installation. This is Step 1 of the installation process and is required for safety when working with the vehicle's electrical system.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This is especially important when drilling the 3/32" pilot hole for the ground wire screw near the taillight connector. The manual warns: 'Check for miscellaneous items that may be hidden behind or under any surface before drilling to avoid damage and / or personal injury.'
Locate the vehicle's taillight wiring harness connectors behind the taillight housing. Separate the connectors from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors on the driver side. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the harness end with the green wire.
Mount the black converter box on a flat spot inside the vehicle near the taillight using the provided double-sided tape. The area should be clean and flat to ensure the tape adheres properly. The converter box houses the electrical conversion circuitry and must be positioned to allow the power wire to route from the battery and the signal wires to connect to the taillight harness.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole. The area should be free of rust, dirt, and paint. Secure the white ground wire using the ring terminal and the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface.
Route the black power wire from the vehicle battery to the converter as shown on the included CME-PCL-INS instruction sheet. Route the wire through any existing rubber grommet in the trunk area if applicable. When passing the power wire through sheet metal, use an existing grommet, add a grommet, or use silicone to protect the wire from sharp edges. Secure the power wire to the vehicle chassis using the provided cable ties. Avoid pinch points and hot or rotating components.
The power wire from the battery must be 12 GA (12 gauge) wire or larger. This wire carries the battery power to the converter and must be properly sized to handle the electrical load safely.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route the 4-flat to the center of the vehicle. Secure any loose wires with the provided cable ties.
Install the fuse after all other installation steps are complete. The fuse holder comes with a 10-amp fuse maximum. Do not install the fuse until the power wire is fully routed, the converter is mounted, and all connections are made.
Drilling may be required for the ground wire connection. If a suitable grounding point (such as an existing screw with nut in the vehicle frame) is not available, you will need to drill a 3/32" pilot hole. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
The CURT 56333 has the following electrical ratings: Signal circuits (left and right turn) are rated at 3.0 amps per side. Tail and running light circuits are rated at 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
The CURT 56333 uses the following wire colors: Yellow = Left turn signal, Green = Right turn signal, Red = Brake signal, Brown = Taillight (running light). The white ground wire connects to the vehicle frame. The black power wire connects to the positive battery terminal. The yellow and green harness ends connect to the driver and passenger side taillight connectors respectively.
The battery connection must be fuse-protected with a 10-amp maximum fuse. The manual states: 'The battery connection must be fuse-protected, 10-amp max. Exceeding the product rating can cause loss of warranty, overheating and potential fire.'
Yes, you must use a ring terminal for the battery connection. The manual explicitly states: 'Use ring terminal for battery connection.' The white ground wire also uses a ring terminal to attach to the vehicle body.
If using the converter as a powered module for a two-wire system, the red brake wire must be grounded. This is a specific configuration requirement for two-wire trailer systems and differs from standard four-wire installations.
Do not exceed the product rating or your tow vehicle's 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 10-amp maximum fuse. Additionally, when routing the power wire to the battery, avoid pinch points and hot or rotating components.
After installation, test for proper function by using a test light or by connecting a properly wired trailer. This will verify that all signal circuits (left turn, right turn, brake) and running lights are functioning correctly. Ensure all connections are secure and the converter box is properly mounted before testing.
After completing all installation steps: reinstall all items removed during installation, reconnect the negative battery terminal, and install the provided 4-flat dust cover to help prevent corrosion. Test the system using a test light or properly wired trailer to ensure all functions work correctly.
Periodic inspection of all wires and connections should be performed to ensure there is no visible damage or loose connections. Check the battery connection, ground wire, power wire routing, and all connector terminals regularly. This preventive maintenance helps ensure safe and reliable operation of the trailer lighting system.
The CURT 56333 is designed for Dodge Patriot, Caliber, Durango, Caravan, Grand Caravan, and Town & Country models with 12-volt negative ground electrical systems. For other vehicles, consult the vehicle manufacturer or a fitment database.
The battery connection must use a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating, and potential fire.

Perform periodic inspection of all wires and connections to ensure there is no visible damage or loose connections. Check the battery connection, ground wire, and all connector terminals regularly.
First, verify that the negative battery terminal has been reconnected after installation. Check that all wiring connections are fully inserted with locking tabs in place on both the driver and passenger side taillight connectors. Inspect all wires and connections for visible damage or loose connections. Verify that the 10-amp fuse is installed in the fuse holder and is not blown. Test the system using a test light or properly wired trailer. If the issue persists, check that the ground wire is securely attached to a clean, rust-free surface and that the battery power wire is properly connected to the positive battery terminal with a ring terminal.
If only one side is working, check that the wiring harness connectors are fully inserted on both the driver side (yellow wire) and passenger side (green wire) with locking tabs in place. Verify that the connectors were not damaged when separated from the taillight housing. Inspect the wires for visible damage or loose connections on the non-functioning side. Check that the ground wire is securely attached and that the battery power wire is properly connected. If the issue is specific to turn signals or brake lights, verify that the corresponding wire color (yellow for left turn, green for right turn, red for brake) is properly connected.
