The insulation of the SGM/SGW can now be bypassed using the dedicated FCA 12+8 conversion diagnostic connector. This allows for clearing fault codes, motion tests, and ECU programming, suitable for the latest FCA vehicles equipped with the Security Gateway Module (SGW) (built around 2018 and later). The universal FCA 12+8 adapter cable also supports use with other diagnostic devices to read and clear fault codes. It is compatible with professional aftermarket OBD II diagnostic tools such as the Autel Maxisys series and Launch X431.

Using the 12+8 cable connector involves just three steps: 1) Locate and disconnect the 12PIN and 8PIN connectors from the SGW module. 2) Then connect the FCA 12+8 directly to the car's 12PIN and 8PIN connectors (two connectors connected to the SGW). 3) At this point, normal communication with the car can be achieved. Made with high-quality 24AWG automotive-grade material for superior stability and durability, this product offers plug-and-play functionality, stable transmission, and anti-jamming features
