you mean the wires are on the harness but they dont have the connector? if thats the case just go get a connector from any civic, connect it to the harness and plug the sensor to it, im having the same problem, good thing the guy i bought it from paid the 100 to fake the papers, so now i bought a magnaflow cat and oh crap, i have not even checked if my harness still has the connector for an o2 sensor, i dont even know if the car has a sensor, i need to get on that


hope your passes dude
