I just traded for a blaster, It needs a wire harness and ignition coil and kill/light switch. I was told that it is a 2004 although the only serial number I can find is on the motor and it was (3JM-006630) to me it looks like a 2000. I am just wondering if I get a harness for an 04 will it fit if it is a older model? Also this blaster has drums in the front and a manually operated rear brake (if that helps with figuring out the year).
