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 Transit150, Transit250, Transit350 and Transit350 HD (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.

Yes, the CURT Custom Wiring Harness, 4-Way Flat Output, Select Ford Transit-150, 250, 350, HD Trailer Connector Kit (Part #BKDK56327) is designed to fit the 2022-2025 Ford E-Transit.
The CURT Custom Wiring Harness, 4-Way Flat Output, Select Ford Transit-150, 250, 350, HD Trailer Connector Kit (Part #BKDK56327) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
Yes, the Curt 56327 custom wiring harness is designed for Ford Transit SUVs, mini and full-sized vans (S-series). The harness connects behind the driver and passenger side taillight housings. Confirm your vehicle is a 12-volt negative ground system before purchasing.
The Curt 56327 is a custom wiring harness with a powered converter that integrates your Ford Transit's taillight signals and running lights to power a trailer connector. It includes a converter box, wiring for left turn (yellow), right turn (green), brake (red), and taillight (brown) circuits, plus a 4-flat connector for the trailer.
You will need: 6mm socket, 10mm socket, 1/4" socket, T-20 Torx bit, ratchet, cutting tool, flat blade screwdriver, and panel trim remover tool. A drill may be required if a suitable existing screw with nut is not available at the grounding location.
Yes. Step 1 requires you to locate the vehicle battery on the driver side under the front seat and disconnect the negative battery terminal before beginning any wiring work. The battery must remain disconnected until Step 13, when you reconnect it after all other installation steps are complete.
The black converter box mounts on a flat spot inside the vehicle on the driver side using the provided double-sided tape (Step 9). Choose a location that is accessible but out of the way, as the converter must remain in the vehicle during operation.
Remove the taillight housing using two T-20 Torx screws (Step 3). Separate the vehicle's taillight wiring harness connectors from the housing, taking care not to damage the locking tabs (Step 4). Insert the custom wiring harness end with the yellow wire (driver side) or green wire (passenger side) between the separated connectors, ensuring they are fully inserted with locking tabs in place (Step 7). Repeat on the passenger side.
Drilling may be required. Step 8 instructs you to locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle's frame. If no suitable existing screw is available, you must drill a 3/32" pilot hole for the provided ground screw. The area must be free of rust, dirt and paint. Always check for hidden items behind or under any surface before drilling to avoid damage and personal injury.
Step 5 requires you to remove the grommet that the vehicle's taillight wiring harness passes through. Make a cut in the grommet from the middle outwards, large enough to pass the custom wiring harness housing through. In Step 6, reseat the grommet using the provided sealant to seal the cut and around all wires. This modification is permanent and necessary on both driver and passenger sides.
The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed this rating. Exceeding the product rating can cause loss of warranty, overheating and potential fire. Install the fuse only after all other installation steps are complete (Step 13).
The custom wiring harness includes four signal wires: yellow for left turn, green for right turn, red for brake, and brown for taillight. The harness also includes a white ground wire with a ring terminal and a black power wire that connects to the vehicle battery. The 4-flat connector is used to connect the trailer.
Signal circuits are rated at 3.0 amps per side. Tail and running circuits are rated at 6.0 amps total. Do not exceed these ratings or the tow vehicle lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your vehicle's lamp load specifications.
Route the black power wire from the vehicle battery as shown on the included CME-PCL-INS sheet (Step 11). The manual notes that battery location may differ depending on the vehicle. When routing 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.
Secure the white ground wire using the ring terminal and provided screw to a suitable grounding point near the taillight connector (Step 8). The grounding point should be an existing screw with nut in the vehicle's frame, or you may drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint before attachment.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location (Step 12). When in use, route the 4-flat to the center of the vehicle. Secure any loose wires with the provided cable ties to prevent damage and keep the installation neat.
After installation, test for proper function by using a test light or connecting a properly wired trailer (as stated in the Notice on page 1). All steps must be followed to ensure the wiring harness functions properly. Verify that left turn, right turn, brake, and taillight circuits operate correctly before towing.
No. The converter system is designed for use only on 12-volt negative ground systems. Do not attempt to use it on 24-volt systems or positive ground systems.
The manual does not specify a maximum towing load. It states: do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Check your vehicle owner's manual or contact the vehicle manufacturer for your vehicle's lamp load specifications and towing capacity.
Yes, the Curt 56327 is designed for Ford Transit SUVs, mini and full-sized vans (S-series) with 12-volt negative ground systems.
You will need: 6mm, 10mm, and 1/4" sockets; T-20 Torx bit; ratchet; cutting tool; flat blade screwdriver; panel trim remover tool; and possibly a drill for the 3/32" ground hole.
Yes, disconnect the negative battery terminal before starting installation. Keep it disconnected until all wiring is complete, then reconnect in the final step.
Drilling may be required. If a suitable existing screw with nut is not available at the grounding location, drill a 3/32" pilot hole for the provided ground screw. Always check for hidden items before drilling.
The battery connection must use a 10-amp maximum fuse. Do not exceed this rating. Install the fuse only after all other steps are complete.
Signal circuits are rated 3.0 amps per side; tail and running circuits are rated 6.0 amps total. Do not exceed these ratings or your vehicle's lamp load rating, whichever is lower.
No, the converter is designed only for 12-volt negative ground systems. Do not use on 24-volt or positive ground systems.
