Any news please ? 
I have tryed your configuration file with SimDash 1.3.4, original firmware (no buttons) and IRacing.
Some LEDs won't come up because you are using some data which is not available in IRacing (like wheels temp/pressuse or turning lights).
But the LED configured to blink at 7000 RPM works fine and also the LEDs configured with the water temperature.
Probably a silly question: can you confirm your Pro Shift is not disabled?
you can enable/disable the device clicking the "switch" icon in SimDash main scrren.
When the switch is RED the device is enabled and working, when it is gray/black the device won't turn any LED on.
thanks
