Diagnostic Tools for 20V 7A engines

My better half offered to buy a diagnostic tool as appreciation for 
keeping her 1990 90 20v on the road.

Two options I found are Versatile Automotive Diagnostics (VAD) and 
Ross-Tech. Neither show the 20V engine on their compatibility lists. 
Ross-Tech said only 20V turbos from 1990 would work, and VAD was 
unsure and non-committal. I've found two plug-ins under the carpet on 
the driver side.

Does anyone have experience using a diagnostic tool with this engine?
