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 300 (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 Harness, 4-Way Flat Output, Select Chrysler 300 Trailer Connector Kit (Part #BKDK56235) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
Yes, the Curt 56235 is designed for all Chrysler 300 models. The harness connects to the taillight wiring behind the trunk, with separate harness ends for driver and passenger sides.
You will need: 10mm socket, ratchet, panel trim removal tool, Phillips screwdriver, and T-25 Torx bit.
Yes, you must disconnect the negative battery terminal before beginning installation. This is a required safety step performed in Step 2.
Drilling may be required. If no suitable existing screw is available for the ground wire, you will need to drill a 3/32" pilot hole in the vehicle frame near the taillight connector. The area must be free of rust, dirt and paint.
Signal circuits are rated for 3.0 amps per side, and tail/running circuits are rated for 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.
After installation, test for proper function using a test light or by connecting a properly wired trailer. All steps must be followed to ensure the wiring harness functions properly.
The Curt 56235 is a custom wiring harness that connects your Chrysler 300's taillight circuits to a trailer connector. It includes separate harness ends for driver and passenger sides, a converter box, a 4-flat connector for the trailer, and all necessary fasteners and cable ties for installation.
Yes, the Curt 56235 is listed for Chrysler 300 (All), meaning it is compatible with all model years of the Chrysler 300.
Yes, you must remove all trunk floor coverings as the first step. This provides access to the battery, scuff panels, and taillight wiring connectors needed for installation.
On the Chrysler 300, the battery is located on the passenger side in the trunk. You will disconnect the negative battery terminal in Step 2 of the installation.
Pull out on the bottom of the scuff panel and then pull up. Take care not to damage the alignment tabs located on the back of the panel, as these are needed for reinstallation.
The felt liner and speaker are held in place by plastic fasteners, cargo tie downs, and a Phillips screw. These must be removed to access the taillight wiring connectors.
The speaker has connectors on the back that must be separated. The trunk light is removed by pulling it through the felt liner and then separating its connectors. Take care when handling these components to avoid damage.
The taillight wiring harness connectors are located behind the felt liner in the trunk. You will pull back the felt liner to locate them. The connectors are similar in design to those on the custom wiring harness.
Separate the vehicle's taillight connectors from the housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (green wire for passenger side, yellow wire for driver side) between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place.
If no suitable existing screw is available, drill a 3/32" pilot hole in the vehicle frame near the taillight connector. The area should be free of rust, dirt and paint before securing the white ground wire with the ring terminal and provided screw.
Yes, you can use an existing screw with a nut in the vehicle frame as a grounding point if one is available near the connector. The area must be free of rust, dirt and paint. If no suitable existing screw is available, drill a 3/32" pilot hole and use the provided screw.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. This should be done after securing the ground wire.
Route the custom wiring harness end with the yellow wire to the driver side behind the removed scuff panels. Repeat Steps 4 through 7 on the driver side using the harness end with the yellow wire, following the same connector separation and insertion procedure as the passenger side.
The harness has a green wire end for the passenger side, a yellow wire end for the driver side, a white ground wire, and a black power wire. The green and yellow ends connect to the taillight connectors, the white wire grounds to the vehicle frame, and the black wire connects to the battery.
Route the black power wire from the vehicle battery as shown on the included CME-PCL-INS sheet. This sheet provides the specific routing path for your vehicle and should be consulted during installation.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. When in use, route the 4-flat to the center of the vehicle and out of the trunk.
Secure any loose wires with the provided cable ties. This helps organize the installation and prevents wires from becoming caught or damaged.
Reinstall all items removed during installation, including the felt liner, speaker, trunk light, scuff panels, and trunk floor coverings. Reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Exceeding this rating can cause loss of warranty, overheating and potential fire. Do not exceed the product rating or your tow vehicle's lamp load rating, whichever is lower.
Before drilling to create a pilot hole for the ground wire, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Test the wiring harness for proper function using a test light or by connecting a properly wired trailer. All installation steps must be followed to ensure the harness functions properly. Verify that all components have been reinstalled and the battery terminal has been reconnected.
