542687 5 to 4-wire wiring & relay kit converter

This Kuryakyn 5-to-4 wire wiring and relay kit converter is a must-have for riders towing a trailer. It is designed to plug into a Kuryakyn trailer wiring harness, allowing the system to power trailers that require a standard 4-wire setup, covering run, left turn/brake, right turn/brake, and ground functions. A great feature of this kit is the bonus wire, which remains available to provide fused 12-volt power to the trailer for interior compartment lights or keyless entry systems. The kit includes a 4-pin flat vehicle connector, making it a universal solution for integrating your bike's electronics with your trailer's lighting requirements safely and reliably.
