Kuryakyn 7671 Universal Motorcycle Trailer Wiring & Relay Harness

The Kuryakyn 7671 is a plug-and-play universal trailer wiring and relay harness designed for 12V motorcycle applications with separate taillight and turn signals. By routing trailer lighting load directly through the battery via an isolation relay, this harness protects the motorcycle's stock electrical system from overload and eliminates blown fuses.

Key Features:

• Plug-and-play design for straightforward installation
• Isolation relay draws power directly from the battery to the trailer lighting circuit — not from the bike's stock wiring
• Eliminates blown fuses caused by overloading stock lighting or accessory circuits
• Provides standard five-wire output: run/tail, brake, left turn, right turn, and ground
• Bonus wire delivers 12V fused power to the trailer for compartment lights or keyless entry systems
• 24-inch wire/cable length
• Black finish; crimp-style and ring terminal connectors
• Compatible with optional Kuryakyn 5-to-4 Wire Converter (P/N 7675, sold separately) for trailers requiring a four-wire setup
• Not for use on Indian motorcycles

• 1x trailer wiring isolation relay
• 1x universal trailer sub-harness
• 1x inline fuse and Y-wire assembly with heat shrink covered butt connectors
• 1x hardware kit

Note: Receptacle kits are not included, as trailer receptacle styles vary by manufacturer. Compatible with optional Kuryakyn P/N 7675 (5-to-4 wire converter, sold separately). UPC: 191209013752.
