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 E150, E250 and E350 Super Duty (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 56020 is designed for Ford Econoline SUVs, mini and full-sized vans. The harness connects to the vehicle's taillight wiring system via connectors located behind the driver and passenger side taillight housings.
The Curt 56020 includes the custom wiring harness with yellow and green wire ends, provided sealant, cable ties, and a 4-flat dust cover.
You will need a ratchet, a T-15 Torx bit, and a cutting tool. The T-15 Torx bit is used to remove the four screws securing each taillight assembly. The cutting tool is used to cut a slit in the grommet to route the wiring harness.
The manual does not specify whether the battery must be disconnected. Check your vehicle owner's manual or contact the vehicle manufacturer for more information.
Open the rear cargo doors and remove the eight Phillips screws securing the rear scuff panel. Pull the scuff panel out at the bottom and then up, taking care not to damage the alignment tabs on the back. Behind each taillight, you will find the vehicle taillight wiring harness connectors.
Remove the four T-15 Torx screws securing each taillight assembly. Start on the driver side, then repeat on the passenger side. Take care not to damage the locking tabs on the connectors when separating them from the taillight housing.
Yes. Locate the grommet behind the taillight where the vehicle taillight wiring passes from inside the cabin to the taillight. Remove the grommet and cut a slit large enough to route the custom wiring harness through it.
The harness end with the yellow wire is routed on the driver side. The harness end with the green wire is routed on the passenger side.
Insert the wiring harness end with the yellow wire between the separated taillight 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.
Use the provided sealant to seal the cut in the grommet and around all the wires after routing the custom wiring harness through the grommet opening.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll up and store in a convenient, out-of-the-way location inside the trunk.
Secure any loose wires with the provided cable ties. This helps keep the wiring organized and prevents damage during vehicle operation.
Test for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring harness will function properly.
Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
Install the provided 4-flat dust cover to help prevent corrosion. This should be done during the final reinstallation step.
