That is 100% the issue.
RULE: The Neutral Safety Switch (NSS) must be grounded to start the vehicle, but OPEN for the cruise to engage.
In an Auto, the NSS is grounded in PARK and NEUTRAL.
In a Manual, the NSS is grounded when the clutch pedal is all the way down via the clutch switch. (That way, you have to press the clutch to start the car AND pressing the clutch in disengages the cruise.)
If the NSS is rewired from the console to the proper clutch switch, all will work as if it was a manual from the factory. __________________
