Hi - How do I turn "power to 1 switch" into "power to 3"? As is, I have one single-pole switch controlling the one light in my room. I want to add two zones: rope light and wall sconces, each controlled from their own switch, so a 3-gang wallplate. How do I power all 3? This might be a bit remedial; I assume this is as simple as splitting (3 ways) the main power to the switch box, but I need to do it juuuuust right. Is there a good DIY out there, or can you guys gimme the details? Thanks much!
