how to test a MAP sensor

[E30godz]

Ive hooked a MAP sensor up to the SMT-6, but im not getting any readings from it.

its a 2 bar sensor, and has a connector to power, ground, and signal

i wired the power to the SMT-6 powersource, and the ground to the SMT-6 ground, and the signal wire to the load sensor so it will only add fuel during boost (thanks gunni)

BUT im not getting a reading....ive rewired it once already and am not sure what else to do!

Get a multimeter, plug everything in, and (excuse the dirty language... but) blow and suck on it to see if it changes the readings.
