Since you have a 16 pin connector, I expect you have a '94-'96.

For how to check codes see
http://www.corvetteforum.guru/module...=20212&forum=1

For what the codes mean see
https://www.corvetteforum.com/forums...s-84-96-a.html

And welcome to the forum. There are a lot of good people that are willing to help.

Good luck.

Thank you for this information! Yes it is a 1994. So it looks like I need to jump the top middle pin to the bottom middle pin. Hoping that works!

H codes stand for History. They were a previous code that may not be active now.
