Fuel Gauge

My new fuel gauge only has two terminals on it not 3 as shown in Binky's site.
Have I the wrong gauge?

Thanks Kevin,
That was intreresting but not much help. I called Krage and they said the instruction on the work around were in the box. They wern't and then Krage seems to have closed an hour early.
Binkey's info shows 3 terminals, the old one has three and the new one has 2 marked "S" and "I".
This is all OEM stuff anjd I'm using the under seat sender which is the twist in one. I'd like to replace the sender too but can't find one that matches.
