Fog light switch wiring

My friend has a Suzuki SJ410 Santara with no fog light which it requires for its MOT. I have been helping him wire it in but no power is getting to the wires at the pack of the car. Behind the dash on the back of the fog light switch there are 4 female spades, but only 3 male spades on the actual connector.
The colours of the 4 wires are:
Green
Green and Yellow
Red and White
Red and Orange
Does anyone know which are the three correct wires and what order they go on!?

Many thanks
