Funbit, these properties are available for use? If yes, what kind of variables they are each (integer, boolean, etc), could better explain please? I have succeeded in adding an indicator to the engine brake (I know nothing about programming, but researching the material you provided here in github I got), now would like to add an rear axle indicator lift on-off, how can I do this? Sorry my bad English, I used Google Translator.
