Hello need urgent help. Whilst preparing walls for replastering came across jumble of cables linked into connectors. Anyway need to rewire new 2 gang light switch but not sure what goes where. There are 3 cables with Red, Black, Earthing on each (total of 6 wires!!!!) the light switch is 2 gang type with Com,L1,L2 on each gang. Can you please advice. I know which is the live feed cable and i have checked the pendent fittings which all have one cable coming from it presumably running back to switch.PLEASE HELP PLASTERER DUE ON MONDAY.Many Thanks
