It looks like both wires going inot the switch are black. Does that mean that there may be wires somewhere behind the box or pushed aside that would allow me to use these switches. Also, the switches I am currently using aren't x-10 swithces, just regular standard light switches. Lastly, if pcs switches are out is there any other x-10 switch that I can use, even though I may be losing scene settings. It wouldn't be so bad to have to control the dimming with my pronto instead of it being automatic. Thanks a bunch for listening.
