Hi.
Yes to all.
Sorry I can't remember replying to your mail, but to get them to work like DRL properly without having to switch the light switch to fog light setting, you need to do a 10 minuet modification to the light wiring behind the switch, but if your happy with them running on the Fog light switch it is just “plug and play” I got them off eBay link:-

There are others but as long as they say “no errors on the cambus system” they should be good.

Guvs, thanks for responding to my post about replacing the fog lights with always-on LED running lights. Yours looks fantastic.
Can I ask where you got yours? Also, was is just a matter of removing the existing fogs and snapping in the new ones? Did the wire connectors match? Is your box a 2007 same as mine?
