Difference between obd2a and obd2b

How do the two vary on a rywire budget harness with obd1 ecu plugs?

the harness has obd1 plugs on it(no need for a conversion harness) and the ecu is a p28 are there any differences other than potentially the alternator plug and intake air temp plug?

it super sounds like it's been completely converted to OBD1. you may need to provide more information on the application/setup
