It’s reusable, requires no permanent wiring changes, and includes reinforced construction and shielding to keep data transfer stable during troubleshooting and maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cable let my scanner communicate with a gated RAM?\u003c\/h3\u003e\n\u003cp\u003eWhen a vehicle’s security gateway blocks direct access to modules, this adapter provides an authorized route between your scanner and the vehicle’s controller area network. It connects to the factory OBD port and the module’s bypass pins so the scanner can read live data, retrieve or clear codes, and perform diagnostics that would otherwise be blocked.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e16-pin male plugs into factory OBDII port under the dash.\u003c\/li\u003e\n  \u003cli\u003eSmall 2-pin bypass connector inserts into the green SGW module.\u003c\/li\u003e\n  \u003cli\u003e16-pin female accepts your OBD2 scanner or interface cable.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich Ram models and engines are supported by this adapter?\u003c\/h3\u003e\n\u003cp\u003eThis cable was developed specifically for Dodge Cummins RAM 1500 and 2500 trucks from model years 2018 through 2020 using Cummins diesel engines.
