Yes, the Curt 56343 is designed for Ford Flex passenger cars. The harness connects at the driver and passenger side taillights inside the trunk.
The harness is rated for 3.0 amps per side for signal circuits and 6.0 amps total for tail/running circuits. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle lamp load rating, whichever is lower.
You will need: a ratchet, 8mm socket, panel trim removal tool, wire stripper, wire crimper, and cutting tool. The manual also notes that a test light or properly wired trailer is needed to test the harness after installation.
The harness includes: a custom wiring harness with yellow and green wire ends, a white ground wire with ring terminal, a black converter box, a provided screw for grounding, double-sided tape for mounting the converter box, a 4-flat connector with dust cover, and cable ties for securing loose wires.
Open the tailgate. Starting on the driver side, remove the two fasteners securing the taillight. Gently pull the taillight rearward to remove it, taking care not to damage the alignment tabs. Repeat on the passenger side.
Behind each removed taillight, locate the vehicle taillight wiring harness connectors. Separate them from the taillight housing, taking care not to damage the locking tabs. Insert the custom wiring harness end (yellow wire for driver side, green wire for passenger side) between the separated connectors. Ensure the connectors are fully inserted with locking tabs in place.
You may use an existing screw with nut in the vehicle frame as a grounding point, or you can drill a 3/32" pilot hole for the provided screw. The grounding area must be free of rust, dirt and paint. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Mount the black converter box on a flat, clean surface that is out of the path of spray and debris from the rear wheels and road. Use the provided double-sided tape to adhere it. Mounting the box in a protected area is critical; failure to do so can cause loss of warranty, product failure, overheating and potential fire.
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.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll it up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
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 functions properly.
Reinstall all items removed during installation. Install the provided 4-flat dust cover to help prevent corrosion. Test the harness for proper function using a test light or a properly wired trailer.
