I do have 12v to one of the 2 extra wires when the dome lights are on; looks like I could have puddle lamps if I wanted.
Like one of the other posters, I do get 12v at the fuse with the rear defroster on.
What exact wire and in what plug are you getting 12v with the dome lights on? I installed new mirrors months ago that have puddle lights and heat but can't get them to work. It was my understanding that if you have a Focus with door modules, you're SOL as far as getting heated mirrors and puddle lights to work.
