You mentioned tabs, I assumed you meant 'terminals' BUT you mention using paper clip as jumper! I asked what pins(terminals) and you reply with 12.

Review this quite complete document for what you're attempting and TRY again!

https://tech.corvettecentral.com/201...trouble-codes/

Rather than paper clip buy a few correct Metri-Pack 150 Male terminals and fabricate a more suitable 'jumper'.

There are specific instructions in that document for '94 + C4. You car has 16 pin connector and you need to use the DIC and IP cluster display to do diagnostics. It does very well!! Read again!!

If you're jumping wrong terminals it's difficult to tell what you might have done!!
