Is this P13 ob1 or 2??

I can't tell becuase the plugs look different then on the other obd1 ecus I have, let me know!

You can't tell just by the connectors. I'm pretty sure the OBD1 computer has 4 sets as well, one just isn't used. You have post the info on the sticker.

Here is what it says: 37820-P13-J01
555-300255

I looks a a JDM P13 OBD-1, 5 speed. Anyone care to correct me?

just curious how you can tell?? My P28 only had 3 plugs so I started freaking out a bit.

Well, my USDM P13 has 4 plugs and the sticker
"P13-J01" J means JDM and 01 is 5 speed. I think 00 is 5 speed also, not sure tho. So on my ECU, it says P13-N01, for USDM 5 speed.

That all makes sense but how do you tell if it's OBD1 from the label, I ask becuase I'm an idiot and don't know these things and if I did it would save me the risk of another beating from my wife in the future

That I'm not sure about. I don't know what markings the OBD-2 computers have.

If I remember correctly OBD-2 plugs have three rows of pins where OBD-1 has two rows.

That ECU right there is from a 4WS Prelude. I don't know if it will work correctly in a non-4WS car, It might throw check engine codes since it doesn't see the 4WS components.

I've heard of some people messing with it but it never went anywhere. All I can say is try it out and see how it goes. Just plug in the three plugs you have.

Heh, I assume that's what the 4W on the sticker is? I totally missed that
