End Stops and RAMPS 1.4

I have a Prusa i3 which had an ANET board (prior to it burning out...).

I've added a new RAMPS 1.4 board and re-done all the headers to fit however I have a problem with the end-stops. All of the diagrams that I have for the RAMPS board have the end stops as having three wires whereas the end stops for the ANET had only two wires (brown and black).

Can the RAMPS board work with the end stops having only two wires and, if so, which of the three pins need to be wired up with which wire ?

Thanks in advance.

Use the - and S pins. Don't use the +, which is the +5v connection.

Thanks

connect it to the outermost side If you put wrongly on the voltage pin that will be an instant death for mega ,I did once
