I have a 4 wire o2 sensor for my h22 and the my civic harness clip has 3 wires. the 4 colors on the o2 is: 2x black, 1x white and 1x grey and coming from the harness plug is: 1x white, 1x brown and 1x black. i can figure the whites together, the grey and brown one together, and 1 black with the other but where does the other black one go?

 

Do you have a picture of the plug? There is no 3 wire O2 that I know of. Only 1 wire, 4 wire, and some have a 5 wire.

 

maybe one of the wires popped out from the clip. but i fixed it..thanks..
