Blower power wire question please help asap

Hello all, I have 2 wires coming out of my blower Im going to hardwire it to the battery due to a fuse box fire but cant figure out which one it is. There is a green wire and a black on. Can any one tell me which one is the hot "power" wire. Thanks alot BB

Anyone???????????

well i dont see it in my manual , but i would bet the Black is the GROUND as it generally is used for the ground on most vehicles. And the GREEN would be the HOT wire
