I need to replace the rear o2 sensor on my is300, i was wondering if someone could help me with the wiring of a bosch universal o2 sensor. I saw a couple of web pages with descriptions on how to do this but none of them show the four wires. If someone has any information on how to do this please help. Thanks Lexus Fans.
