right to the switched headlight wiring, or the brake light wire, or the power to the headlights, any constant or switched power to one side, the other side grounded.
depending on when you want them on
i have a set of tailights to my headlights, and a set of brake lights to the switch in my yfz front master cylinder
ill buy them and bring them to the ride and we can figure it out then, because im no good with wiring unless its plug and play
