I am contemplating installing SwitchLinc switches in my home but don't understand the yellow wire concept.

If a circuit is already set up to be three-way using standard non X-10 switches, what wire do I use for the yellow wire connection?

Are there any circuit diagrams available on-line that illustrate how to install the switches in the different configurations that are present in houses. (load at end of circuit, load in middle, etc)

Also, do SwitchLinc switches work with ceiling fans, halogen can lights, or flourescent lights?

Last question...does anyone know how to spell flourescent?

Thanks
