I found the location of the sensor. It is located on the top of the clutch assy, above the mechanical pivot. This sensor appears to the be the clutch pedal stroke sensor. There are four wires on this connector, Red, Yellow, White and Green. I can provide pictures if requested.
From another forum: the YLW line from the clutch pedal stroke sensor is the voltage postion feedback and must be opened in addition to the clutch position sensor during cranking. The YLW line on the clutch stroke sensor needs to opened during start with a relay. Reference link to source:
The Fortin documentation identifies the clutch postion sensor tap (also yellow) but seems to indicate that the red line should be opened on the clutch stroke sensor. Does potentially disable the sensor?
