Hi Kim,

Your connection is correct. 

V1, V2 and Vex pins are used for factory trimming and we recommend to leave these pins unconnected/floating.

Only pin #1 (Vout), pin #2 (Ground) and pin #3 (Vs) are required as shown in Figure 1 of the data sheet.

The MPX5700DP measures the difference between pressures applied simultaneously to opposite sides of the diaphragm:
