We had an electrician do some wiring, including wiring two set of switches. The wiring could not be completed because the ceiling needed to be taken down. So he left enough wire to do the wiring later so that we could finish the walls. Now that the ceiling is down the electrician is not available. I could easily do this myself but I don't know which of the two wires goes to which switch as he didn't label them.
Besides hooking up a light and switch temporarily, is there some way to tell which wire goes to which switch?
