I lowered my exhaust to drop the oil pan for a new gasket and it slipped and pulled the O2 wires from the Plug the wires were inserted into.

I have 2 Black wires
1 Green Wire
1 White Wire

The image is the O2 Sensor end of it's connector looking "up"

Could anyone tell me what each color wire pushes into each round hole please (using the numbers below)?

For the sake of labeling lets call the Upper Left in the image #1
Upper Right in the image #2
Lower Left in the image #3
Lower Right in the image #4


Thanks,
Bob
