We removed the ceiling fan in our bedroom and have decided to just install a ceiling light fixture. We have 2 black wires, 2 white wires and a green ground wire from the ceiling fan. We have tried various combinations of connections to the light fixture and we either have a light that comes on with the breaker and won't turn off at the switch or nothing. Any suggestions would be much appreciated. Do we just need to use one set of black/white wires? Both? How do we tell which goes to the switch and where do the other wires go? Help! It's getting dark!
