Hi,
OMG I also collect similar info from my Astra J (I’m an amateur enthusiast) but from a different reason. I only want to add comfort functions to my car. I learnt you are doing a much bigger project here – good luck, have fun with it!
If you want to exchange some info or you only want some spiritual support :-))) pls write to me.
