Alright I finally found a header that has two 02 sensors, one of them is on the header, and one is on the down pipe near the cat. I was wondering how to move the 02 sensor down by the cat, and which one I should move. Should I move the 02 sensor with the green plug or the 02 sensor with the yellowish/clearish plug? How do I go about doing that? Standard wire connected to the 02 wire?
