I'd take the sender out and put it in a pot with a cooking thermometer in 
it. Check it's readings against the sender resistance. The 75 reading is 
wierd, that is with the sender on the front of the drivers side of the 
engine disconnected?

This is correct. Not sure why it was designed this way, but it is. Should 
work correctly with both wires connected correctly. Mine does the same. one 
post is broken :(
