I have a clutch switch wired to digital input 2. It is powers through a 5 amp fuse and a toggle switch. When I activat the toggle it sends 12 volts to the clutch switch. When the clutch is pressed the switch closes and sends power to dI2.  As soon as the clutch starts to engage te switch opens. I have tried di2 as go switch, clutch switch, and gear cut. when using clear cut it shows me activat and off when I press the clutch. It jyet don't dont work.  dI2 set up  pull up resistor off,  high, active edge falling
