lighter

I purchased a 1997 center console insert with cup holders to replace the ash tray unit as the inside console cup holders are horrible and awkward. If you've done this swap, how did you handle relocating the 12v lighter socket?

How do you keep the lighter mounted in the dash hole I see no way to do this is there some sort of tinderman nut that holds it in the dash. We also see no way to mount the ignition switch also
