What Is the FCA 12+8 Adapter and When Do I Need It?
Starting in 2018, Fiat Chrysler vehicles (Chrysler, Dodge, Jeep, Ram, Alfa Romeo, Fiat) include a Secure Gateway Module (SGW) that blocks most aftermarket scan tools from full diagnostic access through the OBD-II port.
What the FCA 12+8 Adapter Does
It bypasses the security gateway by connecting directly to the vehicle’s internal 12-pin and 8-pin diagnostic connectors, allowing your YOUCANIC scanner to communicate fully with all modules.
Where to Connect It
The connection point varies by vehicle but is typically found:
- Behind the glove box
- Passenger-side kick panel
- Behind the infotainment/radio unit
