Hi

Just brought a ceiling fan off trademe was going to install it myself into an existing light socket, but only have red and black wires coming out of the ceiling and the fan controller box (it also has a light incorporated) was four connections green, blue, white and black. I am assuming I'm not going to be able to use the existing wires on their own to get this to work and that I'll have to get an electrician in to connect up some new wires?

Thanks
