1g cars use ALDL connectors and are OBD1. 2g cars are OBD2 and have many more monitors, different codes and use completely different software that will be read by a completely different scan tool/code reader. You would have an easier time trying to wire in a 98 Civic ECU than trying to put a 1g one in and make it work and pass Emissions and have no engine lights.
If you took the complete engine wiring harness out of a 1g and replaced yours with it, the car would run, but it would be no fun at all if you needed to do aircare, scan it, or other things.
