Try this, but if not 100% sure ask how to test.

TACH SENSOR GREEN (AC) ECM below GLOVE BOX *2

TACH SENNOTES:

*1 - The Integrated Module is located to the left of the steering column.

*2 - On the turbo models the tach is in pin 9 of the 24 pin plug. The tach wire is also found behind the instrument cluster in the 10 pin plug.
