Quick electrical help

[Kiwi66]

Santa was good to me and I now have an HID light and HID fogs. Now, I am not the most proficient at electrical stuff but after searching far and wide through this forum I was confident enough to begin.
Right, after a "little" while I managed to get the Main beam up and running and buoyed on by this success I have now started on the fogs. According to Les and others for the switch I need to tap into a power supply that is constant after ignition. I chose to use the side light as it will be closer to the switch. Peeling back I have exposed the two cables, one brown and the other white and blue.
My tossers gut is telling me to go with the white/blue.
Do I go with my gut?

If you don't want to go with your gut, you can have some of mine. It's plentiful.

....and yes - blue/white would be the one to go for. Brown is earth.

Great

Many thanks little red.
It seemed logical, but just needed assurance from someone more knowledgeable than I.
