there seems to be alot of questions and issues about relays and how to build a harness. I made this diagram some time ago when i was part of a grandprix forumn, but you will get the general idea. This can be used for: SPAL fans, horns (substitute switch for momentary), HID lights, LED lights, and just about any 12v acessory. With the raptor or any yamaha quad for that matter make sure you ground to the battery, not the frame, I promise you will burn out your regulator if you do ground to the frame.
