CURT custom wiring is the best option for equipping your vehicle with a trailer wiring connector. It offers a vehicle-specific solution with no need for cutting, splicing or soldering. However, if custom wiring is not available for your specific vehicle, CURT offers the taillight converter -- a universal trailer wiring option. This CURT taillight converter provides a standard 4-way flat connection for hooking up your trailer lights to your vehicle. It features highly durable construction, able to withstand harsh elements, road salt and vibrations. The converter is built with a potted enclosure in which the electrical components are encased in a solid compound that seals them off from moisture and impacts. Even when mounted outside, underneath the vehicle, it provides long-lasting dependability. This taillight converter is compatible with a wide variety of vehicles, including models from Dodge, Ford, GM, Honda, Kia, Mazda, Nissan, Subaru, Toyota, Volkswagen, Volvo and many others (to verify your vehicle compatibility, see the CURT application guide at curtmfg.com). The converter is designed to convert a 3-wire vehicle system to function with a 2-wire trailer system. The converter features color-coded wires and a wiring guide for easier installation, and it comes with snap locks for a secure connection (powered taillight converter wiring kit #55151 also included). Most CURT taillight converters are constructed with surface-mount technology or SMT. This type of circuitry features smaller electrical components that mount directly to the face of the circuit board, resulting in reduced heat generation, enhanced performance under vibration conditions, maximum light intensity and maximum operating life. CURT converters are also fully tested, both optically and load-tested, to ensure reliable performance.

Authorized DealerThe Curt 59496 is a taillight converter that adapts vehicle taillight wiring to a 4-flat trailer connector. It converts either two-wire or three-wire vehicle taillight systems to provide independent brake, tail, left turn, and right turn signals for trailer use. The converter must be used on 12-volt negative ground systems only.
The Curt 59496 is designed for SUVs, mini and full-sized vans, passenger cars, and pickup trucks. Your vehicle must have a 12-volt negative ground electrical system. The manual provides wiring location guides for these vehicle types (S for SUVs/vans, P for passenger cars, T for pickup trucks), but does not list specific year, make or model compatibility. Contact Curt Manufacturing or consult a fitment database for your specific vehicle.
No. The converter system is only to be used on 12-volt negative ground systems. It will not function on 24-volt systems or vehicles with positive ground electrical systems.
The kit includes the converter box, snap locks for wiring connections, double-sided tape for mounting, cable ties for securing wires, a white ground wire with ring terminal, a screw for ground connection, a 12-gauge power wire with butt connectors, and a fuse holder with 10-amp fuse. The fuse should be installed after all other installation steps are complete.
You will need a multimeter set to DC volt setting or a test light to identify vehicle wiring types and functions. You may need a drill with a 3/32" bit if you need to create a pilot hole for the ground screw. The manual does not specify other tools required.
Yes. Step 3 of the installation instructions requires you to locate the vehicle battery and disconnect the negative battery terminal before wiring the converter. The negative battery cable must be disconnected before wiring the power wire to avoid electrical hazards.
With the vehicle running and all lights off, probe the taillight connectors while still connected. Using a multimeter on DC volt setting, any wires carrying less than two volts will not be used. Using a test light, any wires that illuminate the bulb (dim or fully) will be used. Activate each light circuit one at a time (left turn, right turn, tail, brake) and probe the remaining wires to determine if your vehicle uses a two-wire system (combined stop and turn signal with independent tail) or three-wire system (independent stop, turn, and tail signals). Refer to the 'How to Determine Vehicle Wiring Types' chart on page 2.
Locate a flat spot near the taillight. Adhere the black converter box using the provided double-sided tape and secure it with the included cable ties. The manual provides wiring location guides showing eight possible locations for SUVs/vans (S1–S8), seven for passenger cars (P1–P7), and five for pickup trucks (T1–T5), ranging from behind taillight housings to under rear floor panels or behind bumpers.
Using snap locks, attach the input wires of the taillight converter to the corresponding vehicle harness wires identified in your wiring type. For a two-wire system: green wire to right stop/turn, yellow wire to left stop/turn, brown wire to tail wire, and red wire grounded. For a three-wire system: green wire to right turn, yellow wire to left turn, red wire to stop wire, and brown wire to tail wire. Refer to the wiring installation table and photos A, B, and C on page 3.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, 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 the provided screw. Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury.
Route 12-gauge wire or larger from the converter to the vehicle battery location, taking care to avoid any pinch points and hot or rotating components. Use a ring terminal for the battery connection. Install a fuse holder with a 10-amp fuse maximum on the positive battery connection. The fuse should be installed after all other installation steps are complete.
Install the 10-amp fuse after all other installation steps are complete. The fuse holder should be installed on the positive battery connection and must not exceed 10 amps maximum.
Use the provided cable ties to secure any loose wires. This helps prevent wires from becoming pinched or damaged and keeps the installation neat and organized.
When in use, route the 4-flat to the center of the vehicle. When not in use, secure it in a convenient out-of-the-way location to prevent damage or interference.
Signal circuits are limited to 3.0 amps per side. Tail and running circuits are limited to 6.0 amps total. The battery connection must be fuse-protected with a 10-amp maximum fuse. Do not exceed the product rating or the tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating, and potential fire.
Before drilling to create a pilot hole for the ground screw, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. The area where you drill should be free of rust, dirt, and paint.
Two testing methods are available. With a test light: attach the ground lead to the exposed ground terminal of the 4-flat end, then activate the tow vehicle's left turn, right turn, tail, and brake lights one at a time. Probe the three receptacles of the 4-flat end to confirm proper functionality. With a trailer: mate the 4-flat with the trailer and run the same test using the trailer lights. If a trailer light function does not work, disconnect the trailer 4-flat, turn vehicle functions off, and recheck with a circuit tester. If functionality is good, check the trailer for problems.
Disconnect the trailer 4-flat connector from the converter. Turn the corresponding light function off on the vehicle. Using a circuit tester, recheck the function at the converter's 4-flat receptacles. If functionality is good at the converter, the problem is with the trailer. If functionality is still not working, the problem is with the converter installation or wiring.

Drilling may be required. You need to drill a 3/32" pilot hole only if no suitable existing screw with nut is available for the ground connection. Before drilling, check for hidden items behind or under surfaces.
The battery connection must use a 10-amp maximum fuse. Do not exceed this rating or the product warranty may be lost and overheating or fire may result.
