I have been thinkin this for a while. How hard would it be to mod the suburbans round map lights to come on when you open door? I mean the ones In front overhead. They are negative controlled right? So they have constant 12v and the pushbutton supplies them with ground? If that is the case, then i could borrow the controlled ground from the center row dome light? Im pretty sure someone hash done this, but couldnt find any post about it.
