How do I connect a fan with only 2 wires from my ceiling box?
I only have 2 wires coming out of my ceiling electrical box. Both are green, though there was a fan attached to it previously so I know one is hot and one is the ground. The Harbor breeze fan I just bought has 4 wires. Blue for the light, Black for the Fan, White which is says it common to both, and a green ground. Would I need to replace the box in the ceiling for this? Or is it possible to do it with just the 2 wires currently there?
