I just assumed they had an OBD-II port

Honestly it's such a stupid idea to not have a standard diagnostic port in there especially considering the standard has already existed for over 20 years

Fiat 500e at least has an obd 2 connector, though it seems like it it speaks a different language.

I would be surprised at that; my understanding is OBD-II is just a breakout for the vehicle's CAN bus.

A bus. There are several in most cars.

Fiat implemented a "firewall" for their port, without the right device you cannot connect to it.

It was implemented to prevent thefts, people hack the car through the ODB port or through the CAN bus connection.

Its easier for them to lock down access rather than fix the fact you can drive a keyless car without the key.
