There are 3 wires on the map, 5v, ground, and signal. The 5v and ground should be easy to identify, and the signal wire is the other one, probably the one in the middle. You can just connect it to a 5v battery and measure the signal prong if you want to. With the sensor in open air, a 1bar will be around 5v, 2bar around 2.5v, and 3bar around 1.6v. I say around because there is a voltage offset and slope adjustment, but it should be close to those values. Put you positive lead on the signal wire, and negative on the ground wire.
