This is the MAP sensor (attached), yes it is a 3 wire MAP sensor.
Both the 2 BAR and the 3 BAR are. As you prolly know, All MAP sensors work on sending a signal to the ECU (0 to +5V). So one wire is ground, one is +5V and one is signal, so yeah, It'll suit yours. If you are in Brissie I can prolly give you a hand wiring it up if you want.
