Not sure what you are asking but take a good look at
I've purchased from these people AND contacted them on several occasions

Which Fiat model are you looking to connect to?
I use hardware/software from Gendan (ELM interfaces) on my Stilo and
Barchetta. They also support CAN etc.
Maybe you are after the older Fiat link protocol?
