cruise control

[ChevyTech]

its got me intrigued now why i have both the clutch switch and the brake light switch!! i might do a bit of testing etc over the w/end to see exactly what function the clutch switch is providing. i can see that the one wire goes from the clutch switch to the brake light switch, and then from there to the cruise control module........................

I have schematics that show both switch are wired in parallel. If one switch fails the other switch will turn off the cruise when the brakes are applied.

Some manual shows both switchs on 2WD and others show the second switch only on the clutch.
