I'm not familiar with that model. I went to the Snapon school for the Modis, Solus, and Ethos. You have something newer that apparently doesn't use those keys.
I was under the assumption that the power and data wires were all standardized on all vehicles with the OBD2 system, but there were also some manufacturer-specific terminals that will be different. Manufacturers' scanners are designed to work with just their vehicles, although the Chrysler DRB3 would work on any brand but just for emissions-related stuff. I suspect a different terminal is needed in the OBD2 connector for non-engine-related stuff, and that's why Snapon needed different keys for each vehicle to connect to those other terminals. Too bad they didn't standardize everything right away. Your scanner must select the right terminal either automatically, based on the vehicle you enter, or you have to tell it which wire to use, but you're saying there's no place to make that selection.
The best thing I can suggest is to contact Snapon directly. Do an internet search for "Horizon Center, Snapon" and see if there's someone you can contact in technical support. That Center is part of Gateway Technical College in Kenosha, WI. If they don't have an answer for you, there isn't one.
