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 Toyota Tacoma (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 56349 Custom Wiring Harness is designed for Toyota Tacoma pickup trucks. Confirm your vehicle model matches before purchasing.
You will need: ratchet, 10mm socket, panel trim removal tool, wire stripper, wire crimper, and cutting tool.
Yes. The first step is to locate the vehicle battery on the driver side under the hood and disconnect the negative battery terminal.
The battery connection must be fuse-protected with a 10-amp maximum. Exceeding this rating can cause loss of warranty, overheating and potential fire.
Drilling may be required. If a suitable existing grounding point (screw with nut in vehicle frame) is not available, you will need to drill a 3/32" pilot hole for the provided ground screw.
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. Failure to mount in a protected area can cause loss of warranty, product failure, overheating and potential fire.
The kit includes a custom wiring harness with yellow, brown, red, green and white wires; a black converter box; a ground screw with ring terminal; double-sided tape for mounting the converter box; cable ties for securing loose wires; and a 4-flat dust cover. The kit also references an included CME-PCL-INS sheet for battery power wire routing instructions.
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 product ratings or the tow vehicle lamp load rating, whichever is lower.
The 56349 is specifically designed for Toyota Tacoma pickup trucks. The manual does not list compatibility with other models or brands. Contact the manufacturer or check the vehicle fitment database to confirm compatibility with other vehicles.
After removing the taillight and separating the vehicle taillight wiring harness connectors, insert the custom wiring harness end with yellow, brown and red wires between the separated connectors. Make sure the connectors are fully inserted with locking tabs in place. Repeat on both driver and passenger sides.
The taillight is secured with 10mm screws. Use a 10mm socket and ratchet to remove them. Take care when prying the taillight out to avoid damaging the alignment tabs.
Locate a suitable grounding point near the taillight connector, such as an existing screw with nut in the vehicle frame. If none is available, drill a 3/32" pilot hole. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. Before drilling, check for hidden items behind or under any surface to avoid damage or personal injury.
Route the custom wiring harness end with the green wire out through the hole between the vehicle bumper and body, to the passenger side, and up through the hole. Insert the housings into the vehicle connectors.
When not in use, roll up the 4-flat connector and store it in a convenient, out-of-the-way location. When in use, route it to the center of the vehicle. Secure any loose wires with the provided cable ties.
After installation, reinstall all items removed during installation and reconnect the negative battery terminal. Install the provided 4-flat dust cover to help prevent corrosion. Test for proper function by using a test light or connecting a properly wired trailer.
If a suitable existing grounding point is not available, drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for hidden items behind or under any surface to avoid damage or personal injury.
Do not exceed the product rating (signal circuits 3.0 amps per side, tail/running circuits 6.0 amps total) or the tow vehicle lamp load rating, whichever is lower. Exceeding the rating can cause loss of warranty, overheating and potential fire. The battery connection must be fuse-protected with a 10-amp maximum. The converter box must be mounted in a protected area away from spray and debris; failure to do so can cause loss of warranty, product failure, overheating and potential fire. Before drilling, check for hidden items to avoid damage or personal injury.
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.
