I have a problem. I have a faulty outside PIR security light and removed it to replace it with a new one. The cable through the wall to the light is a 3 core and earth cable, but the new security light has instructions for wiring to a 2 core and earth cable. I should have paid attention to how the old light was wired but I didn't. The problem is the instructions show where to attach the brown, blue and earth cable to the light's junction box but not what to do with the fourth yellow cable. The three core and earth cable goes through the wall into a fused switch in the bedroom which also has a 3 core and earth and a 2 core and earth able going into it. At the moment the yellow cable from the 3 core and earth is directly attached to the yellow of the cable going to the outside light.
Basically I just need to know what to do with the yellow cable supply to the securit light.
Hope you can help
