Actually, OBDI is really from 1988-1995. But it was updated in 1992.

This is true but most people call the 88-91's non-OBD or OBD0. OBD is On Board Diagnostics which the 88-91 cars do have, so they technically are OBD. The 88-91 cars have a CEL but the ecu flashes the code on it's own LED light. The 92+ cars have the CEL which also blinks the error code when you jump the check connector.
