Kuryakyn 7673 Trailer Wiring Harness with Relay for Motorcycles

The Kuryakyn 7673 Trailer Wiring Harness is an upgraded relay-based solution designed to safely power your motorcycle trailer's lighting system without overloading your bike's electrical circuits. This intelligent harness routes trailer lighting loads directly from the battery rather than through your motorcycle's stock lighting or accessory circuits, eliminating the risk of blown fuses and electrical issues.

Key Features:

• Relay-based design protects your motorcycle's electrical system by drawing power directly from the battery
• Prevents blown fuses caused by overloading stock lighting circuits
• Uses motorcycle inputs to intelligently control power distribution to trailer lighting
• 5-wire plus 1 configuration: provides standard run, brake, left turn, right turn, and ground connections
• Bonus fused 12V wire for independent trailer accessories like compartment lights or keyless entry systems
• Includes 5-to-4 wire converter with 4-pin flat vehicle connector for trailers requiring combined turn/brake signals
• Bonus wire remains functional even when using the 4-wire converter

This comprehensive wiring solution is ideal for motorcycle riders who tow trailers and need a reliable, fuse-protected connection that won't compromise their bike's electrical integrity. The included converter ensures compatibility with both 5-wire and 4-wire trailer configurations.
