How do you get the check engine light codes that start with the P101 example

I have a 99 honda Civic EX with a 99 SI ECU GS-R Swapped Where is the plug for the scanner tool to go into (obd2 plug)

I know how to check it with the two pin plug= if i do it this way are the codes still the same

 

For some CEL codes, you get more information from the OBD2 code than from the OBD1 code. It's near the hood release lever:

 

Thanks man.
