I want to replace a sensor halogen security light which has an interior override switch. The wiring to the outside light is at the light red, blue, yellow, yellow/green. I know I cannot link all four wires but should I wire the blue, yellow and g/y and isolate the live red so that I can use the inside switch to on off on off overrride the sensor and have it on permanently sometimes? I am trying to work out what to do with the extra (live? Positive wire) . Thank you.
