Still not sure what communicates with your vehicle?
Send us the adapter model, vehicle or machine, engine model and year. We will help confirm the correct software and cable before you order.
Compatibility can depend on the exact adapter revision, OEM cable, vehicle protocol, software version, Windows version and license level. “Legacy” identifies older interface generations that may have limited manufacturer support. Brand names are used only to describe compatibility.
