New, improved plug-n-play wiring harness and relay kit designed to protect motorcycle lighting and accessory circuits by routing power directly from the battery. 🔌
The relay harness uses inputs from the motorcycle to direct battery power to the trailer lighting circuits, helping eliminate blown fuses caused by overload.
Kits provide a standard five-wire output (run, brake, left turn, right turn, ground) plus a bonus fused 12V wire for trailer compartment lights or keyless entry systems. Does not include receptacle kits. ⚡
