I did search around here but didn't find an answer... I think what I am looking to do is not possible, or at least easily possible. The lights I am adding will just be wired to switched power..probably marker lights or something I can find in the dash, just not sure what wire and where to tap into aside from piggy backing on the dash fuse panel.
The door switch ground wire that triggers the dome light would turn these additional lights on but I would not be able to turn them on outside of that, without opening the door. Oh well.
