Default What is the difference between OBD2A and OBD2B?

I have a 98 honda civic DX, and i have a 2000 acura B18b1 LS engine i want to swap in and i need an ecu. Can someone tell me the differences in OBD2 A & B so i know which one i can use. Most likely im going to use the engine harness that is already in the car. but i also have the Engine harness from the LS as well. Can i use a 96-99 ecu on my engine? or do i have to get a 2000-2001?

Where the harness plugs into you ecu its dfferent. The ecu is found in the passenger side corner of the car. the design of an OBD2A has a plug, a blank space, a plug and a plug. OBD2B has a plug, a plug, a plug, and a blank space.
