When I was "new" to roadsters.. the wife's car had the divider laid down and that switch has been hard wired or something.. (never have checked it out).. top worked fine.. didn't realize just how things worked till the top crushed an Armor All gift pack. That is when I realized that panel laying down was the "divider panel".. do you see the tank and sending unit-wires when you open the trunk? Or a carpeted piece laying back up in there?
