Default need help finding clutch switch wire off ecu

ive had enough of this search buttun not working

im trying to finish installing a synergy 2-step and cant find the clutch switch wire off the ecu, the instructions say blue connector #35, but that location is empty? so im guessing the directions arent for an 02.

thanks, i was about to tear it apart to test the clutch pedal but no fluk meter. figured it has to be somewhere to also cancel out the cruise control when depressed.
you must be a gm tech to find out so quick... if you ever doing side work for nissans i can get you all the info you need on them
