Here's the arguement....Friend #1 swears its an obd1 ecu...says obd2 ecus have larger plugs....Friend #2 says you can't tell only from that and says he doesn't know, could be obd2 since i was running a 96 gsr motor in a 92 hatch; which was obd1 to begin with.

I'm not sure...you guys tell me. thanks

 

Obd1.

 

looking at the plug set up i would say yes its obd1

That is the part number used on 94-95 GS-R's, so OBD-1 for sure.

 

O b d 1

 

 

Its obd1. You could've saved yourself some time and just googled the numbers you took a picture of.

 

its obd100

 

100% positive its obd-1...and it'll plug into any 92-95 civic/integra ecu harness, or into any obd2-1 harness.

 

obd UNO

 

thats about as unanimous as it gets.
