though down the page its said "By default they measure from ground to 5 volt"
I think that 7-12V "input voltage" is the power supply voltage it wants. Further down under "Inputs and Outputs" it's talking about its sensor pins. The "analog inputs" are what would read your voltage values from the engine controller. Even further down under "Power" it better explains the power supply.
