Kuryakyn 01-10 GL1800 Plug&play Wiring Harness Relay PN 7673

Safely and properly apply the load from the trailer lighting to the battery and not to the rest of the bike's wiring, relays or fuses

Kit provides standard five-wire output (run, brake, left turn, right turn, ground) plus a bonus wire that can be connected as needed to provide a fused 12V power to the trailer for compartment lights or keyless entry systems that are wired independently of the trailer's essential lighting
