Spot Light Switch wiring/pin-out

I Have installed some spotlights on my Defender 130 and used the Land Rover driving light/spotlight switch (pic of light on it with a "2" inside). This switch has 5 pins at the back. Which pins must I connect where to:

1. Operate the spot ligt relay
2. Connect the switch back light
3. Connect the switch on/off light

TNX for all help...
