My name is ***** ***** me get the wiring for you.. As far as resetting the monitors there is a drive cycle that must happen.. Some cars are easy , just drive it some in town and freeway.. shut if off and drive again twice.. and they can reset.. Others are more difficult and may take a couple of days .. I will also get you the actual drive cycle... So BANK 1 Sensor 1 correct

Hello. I am Brian and I will try to help you. I have attached a picture of the connector. Please let me know if this will help you. As far as the readiness monitor status goes, after you repair the connector and clear the codes in the computer you will have to drive the car in order to run all the monitors. Some monitors run more quickly than others. Some require a certain number of drive cycles. please let me know if I can help you in any other way. Thanks.

I'm sorry, I just realized that your looking for the connector view on the car side. Not the sensor side. I will opt out and continue to look for that. If I find it I will reply back with it.
