Thank you, but does anyone have a wire diagram on how to install one on a 2001 frontier? My truck didn't come with one of these, so I guess this would be the best solution (to get the dome light to turn on when the doors are open). Also, since my dome lights are on/off and doesn't have a door/on/off would I be able to wire a on/off switch for the jamb switch? Thanks for the help guys!
