The 1994 and 1995 C-body cars were part of GM's early roll-out of OBD2 as were the Corvettes with LT1s.

The ECM in that car has partial OBD2 capability. If your T2 has software supporting MY95, then you should be able to look at whatever OBD2 content is coming over the DLC, but you are correct in that you will NOT be able to view OBD content with a T2 unless it supports it with the right software. If you T2 does support MY95, then I'd try to connect.

If it does not and you have access to a T1, T1A or a MasterTech along with a software cartridge which supports 95 OBD, then, yes, you need that adapter.

I have that adapter, but it's Vetronix PN 02001575. It is unknonwn to me if PN 3000053 and 02001575 are the same part or two different parts.

It's not for sale but might be available for loan if what you've already obtained doesn't work.
