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 Transit Connect (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 56090 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Ford Transit Connect (Part #BKDK56090) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The Curt 56090 is a custom wiring harness that integrates with your vehicle's taillight wiring to provide trailer lighting control. It includes a converter box that processes signals from your vehicle's taillights and outputs a 4-flat connector for trailer use. The harness is designed for SUVs, mini and full-sized vans, specifically tested on the Ford Transit Connect.
Yes, the Curt 56090 is designed for the Ford Transit Connect. The manual lists this vehicle as the representative application for the SUVs, Mini & Full-Sized Vans category. For other vehicle models or years, consult the vehicle manufacturer or Curt Manufacturing to confirm compatibility.
The harness is rated for 3.0 amps per side on signal circuits (brake and turn signals) and 6.0 amps total on tail and running circuits (parking and tail lights). Do not exceed these ratings or your vehicle's tow lamp load rating, whichever is lower, as exceeding the product rating can cause loss of warranty, overheating and potential fire.
You will need: Phillips screwdriver, flat blade screwdriver, panel trim removal tool, wire stripper, wire crimper, and cutting tool. These tools are required to remove taillight assemblies, separate connectors, route wiring, cut the grommet, and prepare ground connections.
The harness includes: the 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, a 4-flat dust cover, and cable ties for securing loose wires. The manual also references an included CME-PCL-INS sheet for battery power wire routing details.
The manual does not explicitly state whether the battery must be disconnected before installation. However, the instructions require routing a black power wire from the vehicle battery with a 10-amp fuse protection. Consult your vehicle owner's manual or a qualified technician before working with battery connections.
Open the rear cargo doors. On both sides of the vehicle, locate two plastic wing nuts securing the taillights in place. Remove the taillight assembly to access the vehicle taillight wiring harness connectors. Take care not to damage the locking tabs when separating the connectors from the taillight housing.
Insert the custom wiring harness end with the yellow wire between the separated taillight connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat this process on the passenger side using the green wire end of the harness after routing it through the grommet.
Drilling may be required for the ground connection. You will need to locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing screw is available, you must drill a 3/32" pilot hole for the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and/or personal injury.
Drill a 3/32" pilot hole for the provided ground screw. The grounding point should be located near the connector on a suitable flat spot in the vehicle frame, and the area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal.
Yes. Locate the grommet behind the taillight where the vehicle taillight wiring passes through from inside the cabin to the taillight. Remove the grommet and cut a slit large enough to route the custom wiring harness through. After routing the wires, reseat the grommet using the provided sealant to seal the cut in the grommet and around all the wires.
Route the custom wiring harness end with the green wire out through the grommet opening and through the slit in the grommet. Continue to route the green wire out the bottom side of the vehicle along the existing wiring harness to the passenger side, then through the passenger side grommet. The black power wire should be routed from the vehicle battery as shown on the included CME-PCL-INS sheet. When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The converter box should be positioned so that the wiring can be routed cleanly and the 4-flat connector can be accessed when needed.
Use the provided cable ties to secure any loose wires. This helps prevent wires from becoming tangled, damaged, or interfering with vehicle operation. Route the 4-flat connector to the center of the vehicle and out of the trunk when in use, and roll it up and store it in a convenient, out-of-the-way location inside the trunk when not in use.
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 lamp load rating, whichever is lower.
The harness has three main wires: yellow wire (used on the driver side taillight connector), green wire (used on the passenger side taillight connector and routed along the vehicle frame), and white ground wire (connected to a grounding point on the vehicle frame using the provided ring terminal and screw). The black power wire is routed from the vehicle battery as detailed on the included CME-PCL-INS sheet.
After installation, test for proper function by using a test light or connecting a properly wired trailer. This confirms that the signal circuits (3.0 amps per side) and tail/running circuits (6.0 amps total) are functioning correctly. All steps must be followed to ensure the wiring harness will function properly.
Reinstall all items removed during installation, including the taillight assemblies and any trim panels. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function using a test light or a properly wired trailer. Secure any loose wires with the provided cable ties.
Do not exceed the product rating or your tow vehicle lamp load rating, whichever is lower. The product is rated for 3.0 amps per side on signal circuits and 6.0 amps total on tail/running circuits. Exceeding these ratings can cause loss of warranty, overheating and potential fire. Check your vehicle owner's manual or contact the vehicle manufacturer for your specific tow vehicle lamp load rating.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and/or personal injury. The grounding area should be free of rust, dirt and paint. If using an existing screw with nut in the vehicle frame, no drilling is required; only if no suitable existing screw is available should you drill a 3/32" pilot hole.
The Curt 56090 is designed for the Ford Transit Connect and other SUVs, mini and full-sized vans. Confirm your specific vehicle model with Curt Manufacturing or your vehicle's owner's manual before purchasing.
