I'm wondering if anyone can tell me the location of where the o2 sensor plugs in on the jdm b16a obd1.

I have a jdm b16a obd1 with a apexi ws2 exhaust, vibrant j-spec header, test pipe, brand new o2 sensor and stock ecu to replace all the garbage parts that were on the car when I bought it.

Problem is that it was running an open loop with a tuned ECU and it didn't have an o2 sensor hooked up to begin with. Can anyone show me a detailed picture of where I'm supposed to hook it up? Everything seems to be plugged into something around the distributor/passenger side of the block.

Any help would be great, I've searched around but haven't found much help.

Matt.

I'm confused, are you looking for the connector, where it goes to the ecu or where does the o2 go itself on the exhaust?

Sorry for being so vague, I am looking for the connector. I have the o2 sensor, I know where it hooks up on the Header as there is only one o2 sensor for the b16a and no secondary. I don't however, know where the plug connector is on my vehicle. Is it on the block? Near the dizzy? I have no idea as I've never dealt with an o2 sensor before. Any help would be appreciated.

Should be near the manifold around the transmission

Thank you. I'm not sure if the harness was cut and the o2 sensor connector was cut or if its just plugged into something already but I can't seem to find that four-pin connector. Judging by your last post I can somehow wire it up directly to the ecu if this is my problem?

Is there anything you can't do? That picture probably answers 20% of the most frustrating electrical questions. Thank you very much I really appreciate your thoroughness!
