It's definitely obdII. I don't know how to tell if it's a or b though. I thought the main difference was the addition of the immobilizer in the 2b.

 

Actually that is an OBD I ecu....from an auto. The OBDIIs plugs go all the way from the top/bottom covers, that one still has the thinner OBD I plugs, but has the 4th plug for the auto portion. Not sure if all the autos had the 4th plug or not, but I know it was common on the JDM B16s and probably on the LSs as well.

Oh boy, how wrong you are.

95 Integra hit the nail on the head.

 

I don't know if they weer P72's but there were auto GSR's in Japan. My OBD-1 DA auto had only 3 plugs but it had a seperate computer unit for the auto tranny, whereas the DC's probably had the tranny stuff integrated into the ECU where the 4th plug could possibly have come from. But like it was said, it says DC B18B anways on the top.

 

but its said p72 on the side of it can i still used it for manual car?
