Lonsdor FCA SGW 12+8 Special Adapter

The Lonsdor FCA SGW 12+8 Special Adapter is a hardware adapter used when working with FCA (Fiat Chrysler Automobiles) vehicles — including Chrysler, Dodge, Jeep, RAM, Fiat, Alfa Romeo, Lancia and Maserati models from around 2018 onward. It’s designed to interface with the security gateway module (SGW) found in these vehicles so that key programming and diagnostics can be carried out more easily with a compatible programmer or diagnostic tool.

Key Notes

• Supports multiple key programming and diagnostic tools, not limited to Lonsdor devices like the K518 series.

• It has a built‑in Security Gateway Module (SGW) to make connection faster and simpler.

• The adapter is compatible with common 12+8 wiring harnesses for FCA vehicles.

• It is not suitable for some 2021+ models where the SGW function is integrated into the BCM (Body Control Module).
