X90 "clutch position switch" Questions

[maint]

2 switches for the clutch. left is cruise , right is starter.
the blue wire marks CRUISE

this blue wire prevents engine screaming during cruise and you depress the clutch,  a horrific event, possible.

Ah now it makes sense. The clutch pedal cruise switch had been mushroomed on the end so the plunger couldn't ever come out but it didn't seem to affect anything. Two minutes with a file fixed it. But... it would scream in cruise with clutch disengaged. I thought that was just the nature of the beast.
Thanks
