I have a room with a ceiling fan and light both controlled by one on/off switch. I bought a dimmer switch that has separate dimming controls one for the light and one for the fan. When I opened the wallbox, I saw three wires attached to my swicth. One was the ground, and the other two were both black. My dimmer switch came with FOUR wires - green, yellow, red, black. I know the green goes with the ground and I was able to match the red and yellow wires according to the diagram, but I do not know what to do with the black wire from the dimmer. It says to attch the black wire to the "feed wire from the circuit breaker." There are a bunch of other wires in the wallbox that are capped and connected with each other. How should I proceed?? Thanks. -Chris
