I am trying to install two new lights in my kitchen, but one light has just 1 cable running to it ( red,black and yelow) but the other ceiling rose has a cable with 4 wires in (red, black, yellow and a fourth cable). I also have a cable running back to the light switch.
Can anyone tell me after i have joined the red to red, black to black and earth to earth, what do i join the fourth wire to?
at the moment, i have joined up all cables except this fourth one and the lights work bu the light switch doesnt swith them off!!
