Many vehicles use separate circuits for brake and turn lights, which can cause trailer lights not to work correctly. This converter takes those separate signals and combines them into one—exactly how trailer wiring operates—so the turn and brake lights on the trailer flash just like they should.
When hooked up with the Curt Powered Converter Wiring Kit # C55152, the black power wire draws power straight from the vehicle’s battery instead of the tail light circuit. That means the trailer lights get full brightness every time, even on vehicles with pulse-width modulation (PWM) or sensitive lighting systems.
Whether your trailer uses LED or traditional bulbs, this 4-pole flat connector handles it. It supplies running, turn, and brake light signals so your trailer stays visible and road-legal. The design is compatible with LED taillights since the converter isolates the signal voltage from the lighting load.
This splice-in kit uses clearly marked wires—green for right turn, yellow for left turn, red for brake, brown for running lights, white for ground, and black for 12-volt power—making it easy to match each circuit with a simple circuit tester. Once connected, you’ve got a clean setup ready for towing.

Still the best product ever, because it is powered and my trailer lamps are bright as ever. I stand by my original review of April, 2022 !
