I'm trying to install an all in one ceiling fan/light control wall switch. My wiring is old & no longer color coded inside the wall switch box. There are 2 wires connected together inside the box which I know are hot & 3 others I need to identify. There are 2 wires at the ceiling box, white & black. I've already shorted out one control switch by incorrectly wiring it. How do I wire this correctly?
