You don';t have a full part number on your sensor. See the GM PART number on the sensor in the picture you posted? One of those.

The GM 3 bar MAP has a distinctive arraingement of aligning slots on the 3P plug. If the correct pigtail doesn't plug in, you have 1 or 2 BAR swill sensor that should be round filed.
