The single line, 3 wire sensor, is the intake air pressure sensor. You will need it for proper operation of the fuel injection system.

The other one with the two wire connector is simply a vacuum solenoid that operates the intake flapper valve controlled by the ECM. This one can be removed if you have already done the "airbox mod" and removed the flapper valve.
