Default 98 C5 CMP sensor fault

I know where the sensor is at and what is involved replacing it. But, is it possible to access the connector, to check electrically, without removing the manifold our hiring a real tiny assistant.

For a 1998 The connections at the PCM are as follows.
Low Ref C2-70
Ign. Feed C2-4
CMP Sensor Signal Input C1-4

The circuit numbers and wire colors are the same as the schematic Bill posted
