Does the 85 C4 Corvette have a diagnostic port? I have an engine light that goes on intermittently.

Yes.. It has an OBD1 diagnostic port under the driver''s dash.

I have a scanner but there are two pins you can put together with a paper clip and the engine light will flash out the stored codes.

Yeah, it's a thing I guess..

I dunno why they don't just put it back where it goes?
