New bathroom fan has a 2 prong plug. Old fan was straight wired. How do I convert?
I looked up your fan and this is a picture of it...



It sounds like you just have some romex wire hanging from the ceiling and no outlet to plug the fan into. The wire you see is called romex. This is a large white cable with three wires inside it, Black, white and a naked copper ground wire. These wires should already be stripped but you might want to cut off about 6 more inches of the romex casing to give you some extra room for the ground wire. You can clip off and re-strip the black and white wires, as they will be too long. Cut off the existing plug on the new fan. You will need to strip the wires back. Attach the two wires from the fan to the black and the neutral wires of the romex using wire nuts. That is an Supco SM55OP2 motor equivalent, so both blades on the plug will be the same size. Polarity doesn't matter on these. Finally, attach the ground wire to the frame of the fan with a screw in the provided screw hole. You can also use a self-tapping screw if you have one. Here is a diagram to help you...
