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 Mazda 2 hatchback, Mazda 5 and Mazda CX9 (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 Mazda 2 Hatchback, 5, CX-9 Trailer Connector Kit (Part #BKDK56016) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The Curt 56016 is designed for Mazda 2, Mazda 5, and Mazda CX-9 models. Confirm your vehicle model matches one of these applications before purchasing.
The harness is rated for Signal Circuits at 3.0 amps per side and Tail/Running Circuits at 6.0 amps total. Do not exceed these ratings or your vehicle's tow lamp load rating, whichever is lower, as exceeding the rating can cause loss of warranty, overheating and potential fire.
You will need a ratchet, 10mm socket, Phillips screwdriver, and panel trim removal tool. A 3/32" drill bit is also required if you need to drill a pilot hole for the grounding screw.
The harness includes a screw and ring terminal for grounding, double-sided tape for the converter box, cable ties for securing loose wires, and a 4-flat dust cover. A CME-PCL-INS sheet with battery routing information is also included.
The manual does not specify whether the battery must be disconnected before installation. Contact the vehicle manufacturer or Curt Manufacturing for guidance on this safety step.
Open the vehicle tailgate and remove all trunk floor coverings and storage trays. Then remove the scuff panel by pulling out on the bottom and then up, taking care not to damage the alignment tabs on the back.
Locate the vehicle taillight wiring harness connectors behind the trim panel. Separate the connectors from the taillight housing carefully to avoid damaging the locking tabs. Insert the custom wiring harness end with the yellow wire between the separated connectors, ensuring the connectors are fully inserted with locking tabs in place.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties.
Drilling may be required. You must locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable existing point is available, you will need to drill a 3/32" pilot hole for the provided grounding screw. Before drilling, check for miscellaneous items hidden behind or under any surface to avoid damage and personal injury.
Drill a 3/32" pilot hole for the provided grounding screw. The area should be free of rust, dirt and paint before securing the white ground wire using the ring terminal.
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.
The harness has a yellow wire end for the driver side taillight connection, a green wire end for the passenger side taillight connection, a white wire for grounding, and a black power wire that routes from the vehicle battery. Refer to the included CME-PCL-INS sheet for detailed battery power wire routing.
Once installed, 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, including trunk floor coverings, storage trays, scuff panel, and rear trim panels. Install the provided 4-flat dust cover to help prevent corrosion.
The Curt 56016 fits Mazda 2, Mazda 5, and Mazda CX-9.
Ratchet, 10mm socket, Phillips screwdriver, panel trim removal tool, and a 3/32" drill bit if drilling is required.
10-amp maximum fuse for the battery connection. Do not exceed this rating or the product's amperage limits (3.0 amps per signal side, 6.0 amps total for tail/running circuits) to avoid warranty loss, overheating and fire.
