I have a 3.5 cluster in my 17 Ram 6.7 and I have the red flashing light now.Yes you can enable the alarm. The instructions for all of the options that have been successfully added and how to do it are at the beginning of the thread. One thing I'm thinking you may possibly run into an issue with is as far as I know everyone who has enabled the alarm has also already upgraded to the premium cluster. There's a small red LED that blinks on the bottom of the speedometer dial when the alarm is set. I'm not sure if that LED is present on the regular 3.5" speedometer in order for you to tell of alarm is activated or not. The alarm should still work either way but there may be no blinking light with the regular cluster. There might be someone who has done it with the 3.5" speedometer who will chime in to verify one way or the other on whether or not they have the red LED light.
