I am currently running a 1995 B18c1 jap spec in my 92 ex coupe, and i have no plug for the O2 sensor. I need to come up with a harness or somehow fix this to eliminate my problem...v-tec is not hitting right, and i was told that my ecu is running in default tune mode. so i'm not too happy, and nervous that i'll blow my **** up soon. please help. thanks.

http://www.jdmhondaparts.com has a bung that you can have a shop weld in and then run a o2 to it.

sorry, I may not be that clear with my problem. i have the bung, i have no plug on the harness to run the O2 sensor. i need the plug, I was told since I had the motor shipped from japan, it has a different harness, with no emissions control or something. maybe i'm wrong, but i know I have no oxygen sensor hooked up to my harness.

That's not true because JDM motors utilize O2 sensors. Did you do your own swap or did a shop do it for you? I doubt that the JDM harness was used, but even if it was there should be a plugin for the O2 sensor unless it was hacked. If you can't find one, you could always wire it directly to the ECU pinouts using your own wire.

yes i did my own swap, and it runs pretty good, but i'll look again. I tried all of the plugs that I have left over and none of them fit the open ones off the harness that I have. I bought the motor off of an older guy who put this motor in his crx before I had it. I have the crx harness he used too, but it was no use to me so i sold it to my friend. i'll look again, but about hard wireing it to the ecu, how would I go about doing that? i'm pretty new to this stuff, never been this deep into a car, so i'm learning as i go.
