So i picked up an electric fan today at the junk yard. I bought a ford taurus fan, the two speed one. So now i need help hooking up properly. I was wondering if i can just hook the low speed to come on when i start the truck(until i can aford a controller) and use the wires that are hooked to my stock efan to run the high speed when i turn on a/c or the truck gets over 210?? Thanks
Jon
