Response from AM-Auto Parts
Thank you for your feedback. I do see we have reviewed this issue for you and have confirmed that the difference in wire color and sensor tip will not affect fit or function of the product. The plug and wire length appear to be correct. If you would prefer to not use the product please feel free to reply back to our most recent email and we can further assist you, thank you.

Fixed my oxygen sensor trouble code and passed my smog check.
After viewing YouTube videos advising against buying non honda brand oxygen sensors and clearing the codes 3x and resetting the computer, the car finally accepted the new sensor. I waited over a week to take it in to get the car smoggy and it passed. I would highly recommend this part to fix your issue with oxygen sensor
