C125 & switched input alarm

[fordpop]

Is it possible to set an alarm on the C125 from a switched input to the ECU (M84)?

More specifically:

Im looking to add burnout RPM limit. The way I'd like to set this up is on a simple toggle switch through to DIG 2 input which will activate the dual RPM limit when the toggle switch is on.

However, I'd like the dash to display an alarm when dig 2 is on. Ive tried many parameters today & cannot get the dash to alarm when DIG2 is on. Help please..

If you set up the dash to display the "Dig 2 speed" channel, does its value change when you turn you turn your switch on and off?
