The drl's use 12 volts and are on when you shift out of park even when the bulbs are blown or removed,
Now you just have to find out the voltage of the mirror motor that works the fold feature my guess is it is the same.
Cool i think im geting some good help. Does anyone have wire colers i need to put voltage on for mirrors. And do i need to put it on some kind of timer relay or just leave voltage on it at all times.
