Default Integra GS-R ECU's

For a GS-R ECU, how do you tell if it is OBDI or OBDII? Are all P72 ECU's OBDI?

Look at the plugs on the side and that will let you know what you've got.

If it looks like either of the top 2, you've got an OBD2 ECU.

If it looks like the next to bottom one, you've got an OBD1 model.

I just went to the Hondata site, but I must've missed that link. Thanks for the info!
