Wiring ? 2000 Xplorer 400

I got the ATV running and the previous owner jacked with all the wires. I installed a new ignition switch and corrected most of the wiring. I have one power wire that I can not figure out what it is for, I am thinking fan motor since that is powered with a rocker switch the previous owner installed. The wire is red with a white tracer and I just added the female bullet connection to protect it. Anyone with a ATV like this one? Let me know what it is for.
