Fiat, Alfa Romeo, Lancia 3-Pin to OBD2 16-Pin Adapter Cable

Fiat, Alfa Romeo and Lancia models of the adapter era carry a 3-pin diagnostic interface; every current scan tool carries a 16-pin OBD2 plug. This adapter is the conversion: the 3-pin car interface on one end, standard OBD2 16-pin on the other — high-quality materials give the cable superior flexibility and durability for the daily work of servicing the Italian trio.

It allows you to connect OBDII interface diagnostic tools and is compatible with diagnostic tools using a 16-pin socket. As a passive adapter it routes the vehicle’s diagnostic lines onto the standard port — what the tool can read then follows the vehicle’s protocol and the software’s coverage, the same honest rule every adapter in this class lives by. Match the vehicle’s connector shape to the photos before ordering; the 3-pin family has close cousins.
