I brought a wrecked 2000 cbr600. I purchased a new ignition switch off e bay from a chinese seller, that has three wires and the original switch has four wires. Does anyone know how to wire my new ignition tha thas 3 wires.

 

W/o knowing what you've purchased & how its wired...no. Give us some more info & we'll see what we can do.

 

another question would be is the bike u.s or europe version. the european has an imobilizer right around the switch, which be the extra wire.
