Light/Fog switch wiring?

[cockneyrick]

So this relates to a Caddy, but the A1 is the same. 

I need to know the fog light wiring colour & pin position., as i have fitted a bumper with fogs.

Have changed the switch to a fog one, & all wiring is in place but for the trigger wire from the switch to the relay.

Original non fog switch had 8 of 10 pins, fog enabled has all 10. I need to wire the trigger to the correct pin/wire to get the fogs to work.

Can anyone help?  Pic is of old 8 pin switch.
