It depends on the year of the visors. Some, the earlier ones I believe, use a single power wire and they do ground through the screws. Others have a second black wire that goes back to a chassis ground somewhere.
Check the mounting holes for the visors in your roof. If they have nylon inserts in them, then the screw ground won't work. You will need to bring a ground wire out from above the headliner, crimp an thin eyelet on it and sandwich it between the visor bracket and one nylon insert on each side. This will supply the ground to the metal visor bracket and the mirrors should illuminate.
