Since we’re closing in on the release date, what should we do regarding the cable for the Kia Soul and Fiat 500e? I have yet to find anything really useful on the M-bus, but who knows what might come later.
Jason, how about the Fiat 500e? 

Anyone know the pinouts for Hyundai Ioniq OBD2-port? Maybe it can use the same cable too? I couldn’t find the pinouts for that car anywhere…
