Uknown connector need help fast.

[DSM_munky_man]

Alright guys, some of you may know I am trying to tune my car but have been having 02 sensor problems, well i changed it out today and nothing changed, so the curcit for it tests fine then it led me to think, the PO installed a narrowband so it may be partly due to that, it reads, doesnt oscillate but when accel and decel it reads adn what not. So my though is they just disconnected the feed to the ECU and that is why my comp is not picking anything up. Anywho, here are some pics of the connector it is connected too. The grey wire is coming from the green wire on the NB and it connects into a one pin connector that has a black with red dots wire. This is all located on the passenger side kick panel. Please help I need to get my car tuned, it is running really rough.

Get a multimeter, shoot it from male to female, and adjust things until the readings start changing. Or try to find a wiring diagram and trace it from end to end.

What is the grey wire connected to?

The o2 wire at the ecu is white and in pin location 4 on the long connector. Check for continuity from there to your o2 sensor connector under the hood. You could have the sensor lead and sensor ground backwards on the oe o2 sensor.
