no idea what this is and why it's disconnected ? Ahaha cannot trace the wire does anybody recognise it, has been like this for along time. Bikes been roll starting everyday for about a month tryna find an electrical issue as battery's alllllllllllgood.
Maybe this loom is also used on other brand's / model's , hence being this loom connection not used. Does your fuel gauge work ? , as risky has commented on.
