I have two switches for my ceiling fan. One for the light and one for the fan. I have a red/black/white/green wires coming from the ceiling. I have a black/black&white/white/green wires coming from the fan. First, do I need to have the light hooked up to the fan before installing and if not, how do I hook the wires together. I have tried ever conceivable way possible and it isn't working.
