CURT 2-to-3-Wire Taillight Converter 56196 — Splice-In Dinghy Towing Adapter, 3-Wire Output

The CURT 56196 converts a 2-wire combined stop/turn taillight circuit into a separate 3-wire stop and turn system for safe dinghy or flat towing by splicing into the vehicle’s wiring.

When a vehicle lacks a factory trailer connector or separate brake and turn outputs, a taillight converter like the CURT 56196 provides an effective splice-in solution. Designed primarily for dinghy and flat-tow setups, this compact converter separates the left and right turn signals from the combined stop/turn feed so your towed vehicle displays distinct brake and turn lighting. It’s a durable, surface-mount unit rated for typical trailer lighting loads and intended for installers comfortable with basic wiring and circuit testing.

How does this converter change a 2-wire system into a 3-wire system?

The CURT 56196 takes the vehicle’s combined stop/turn wires and splits them into dedicated outputs: left turn, right turn and a separate brake feed. It uses color-coded inputs and outputs so you can match each wire to the proper circuit. The converter relies on splice-in blunt-cut leads rather than a plug-style harness, which requires making secure electrical splices.

• Input wires: yellow = left stop/turn, green = right stop/turn.
• Output wires: yellow = left turn, green = right turn, red = brake, white = ground.
• Rated at 2.1 amps per turn/brake circuit for common lighting loads.

What tools and steps are needed to install the CURT 56196?

Installation is splice-in style—no dedicated trailer socket or heavy-duty flasher is included—so basic hand tools and a wiring tester are required. You’ll confirm circuit function with a multimeter or test light, cut and splice the blunt-cut leads to the vehicle harness, and secure all connections with quality connectors and shrink tubing or heat-proof tape.

• Tools: wire stripper, crimping tool, multimeter/test light, heat shrink or waterproof connectors.
• No direct battery connection or special flasher module needed for normal taillight loads.
• Verify wire colors and converter labels before finalizing splices.

Will this work for dinghy towing behind an RV?

Yes—the unit is specifically described for dinghy towing because it separates brake and turn signals, which many RV setups require for proper towed vehicle signaling. Confirm that your towed and towing vehicle circuits are compatible and that the converter’s amperage rating covers your taillight bulbs or LED loads.

• Ideal for flat towing where independent brake and turn outputs are needed.
• Not a plug-and-play harness—requires splicing into the towed vehicle’s taillights.
• Check circuit ratings and use a circuit tester before permanent splicing.

How durable and reliable is the CURT 56196 in regular use?

The converter uses surface-mount technology for consistent electrical performance and is built to handle common trailer lighting currents. Because it’s a hardwired splice-in component, durability depends on using quality connectors and proper sealing against moisture and vibration during installation.

• Surface-mount construction for stable connections and long-term performance.
• 2.1 amps per circuit rating suitable for standard bulb lighting circuits.
• Requires correct sealing of splices to prevent corrosion and intermittent faults.

Who is this for? The CURT 56196 taillight converter is aimed at RV owners, boaters and motorists who flat-tow or dinghy tow a vehicle that lacks separate turn and brake outputs. It’s best for DIY-savvy installers or professional shops comfortable with cutting into automotive wiring, testing circuits, and making weatherproof splices. Choose this unit when you need a compact, splice-in converter to create dedicated brake and turn signals without adding a battery feed or heavy flasher module.
