not to steer us back to OBD2, from the OBD1 sidetrack, but I would ask if anyone knows for sure (I haven't tried it yet), but does the "Tech 2" software (GM's propriety - basically Forscan for chevy's) work with the V-linker cable... I am being terribly lazy here and haven't tried it even though I downloaded the software and own the cable and and... But if it works that is another huge vote for a $30 cable instead several different $190+ readers one for each mfg.
I downloaded because I was thinking I would be forced to use it to diagnose the convertible top on my GM - (supposedly it stores all kinds of codes in the BodyControlModule), but I solved it on my vehicle without, and have yet to need it again.
If nobody has a review or comments, I'll get off my lazy butt and see if it works..
