The Tech 2 is no longer supported by GM as far as updates are concerned. Mine has the last update available, ver. 33.004 for US vehicles. They were updated through the GM dealership computer system on line. This software version supports most systems on the Caprice PPV.

If the menu is in the Tech2 for '91 then that hints that all you would need is the correct 16 - 12 connector/adapter and also likely a provision to power it with the adapter. OBD2 is self-powered from the DLC, OBD1 ain't. '94 & '95 would work without the adapter, they're 16 pin DLC with pin 16 being B+.

Also be mindful that GM stopped support on the TECH 2 for models newer than 2013. Some modules still communicate with the TECH2 in 2014+ applications but not 100% support. Therefore you need the GDS tool with the MDI module.
