Review on KAX 234-4209 Universal Oxygen Sensor Replacement - Heated O2 Sensor (Connectors Not Included) by Desmin Dickerson

cheap and does not work. cable color codes. I needed this information to connect my old OEM connector. Your instructions don't describe which wires are responsible for what. Spent more time on it! I used to have these codes: Black Wires for Heater - Anything. Blue - positive signal White - negative signal. Had to crimp the new sensor to the old connector, more time and effort, not worth the money saved if at all, and use their heat activated wire insulators, more time and effort anyway. Then, according to my scanner, the sensor heater was not working and my check engine light came on. I decided to pay the extra $30 and buy an OEM Denso sensor for my Scion Xa. It worked well and was easy to install. Lesson learned - that discounted universal sensor that failed wasn't worth all the time, trouble and BS refund.
