Hi - Just hoping someone can help me out here .... I am 'attempting' to change a light fitting & got myself in a muddle with the wiring. I have a hallway light with 2 light fittings coming off it. There are 2 cables running into the 1st ceiling rose both with a red, yellow, blue & earth wire. Unfortunately I didn't mark where the wires come from, I know, rookie error.. Can anyone advise where each of these wires should go? Unfortunately there isn't one marked for the live switch.
