I've taken out my gas tank, along with the engine and tranny, as part of a Subie conversion project.   On the driver side, by the charcoal cannister, I now find there are two identical 2 pin female connectors where the level sensor plugs in.  I can't figure out why there are two in this area.  One is obviously for the float output, but what else plugs in there?

Thanks for help.
