    Does anyone have access to the pinout information for the gen 3 engine control unit (part # 89661-47390)? I want to find the two wires that go to the downstream oxygen sensor.

    I found out myself the hard way and the blue (+) and white (-) wires of the downstream oxygen sensor correspond with these pins marked by the blue and white circles:

    Since I had to crawl underneath to find this out it defeated my need for this information; I tapped into the wires at the end on the sensor's side of the connector. But maybe this information may be helpful for someone else; if you have a P0420 and want to hack fix it but don't want to crawl underneath the car then you can tap into the wires right here.
