I’m not an expert on this subject by any means however, based on my experience, you’ll need the interface between your engine’s diagnostic port and the pc.  It is available from Silverfish.  You’ll need to know the configuration of the engine diagnostic port, some are round and some are rectangle, pick the one that matches yours from the pictures or description provided on the website.  They are about $400 but the software is free.
The out put of the interface is generally USB.
There are plenty of references to all this information available through the search feature on this site.
