Question is I have a B18B1 Engine and was wondering how could I tell if its obd-1 or obd-2?
Is there anyway I could tell from looking at the engine or engine harness?

I have the engine harness near me right now!!!

I need to know so I know what ECU I need for my swap.
If you guys could help me asap cause I may have a lead on an Obd-2 P75 if that is what I need.
 
If it came from a 94-95 It is OBD1

If it came form a 96+ It is OBD2

If you have no clue, the distributors are wired different, couldn't find a good pic.
 
sorry guys not sure what year it came from... i think its a 96 but cannot be positive...
Im going to snap a picture of the distributor and post for you guys...
 
take a pic of the plugs that go through the fire wall...thats an easy way to tell
