I want to hook my 2 fans (stock)up to a switch in the car so i can turn them on and off as i please...Does anyone know how?

 

cut the wires that go to the fans, find out which wire is the ground and ground it to the chassis, then run a wire from the batter to a switch inside the car and go from that to the positive wire on your fans but if it was me, I would just splice into the factory connection so if you forget to turn your switch on your fan switch will still automatically turn them on, also if you do that you might want to put a diode after your switch before it connects to the positive lead
