[QUOTE="levin818, post: 4029481, member: 849"] Rais, you are running an auto ECU 89661-1A180. It has slightly difference in pin out with M/T's. SVT's O2 sensor has 4 wires. As Chinozie said, 2 is heating element (HT) and another will supply signal to ECU (O2). You can easily identify it on the system hardness by tracing it to the ECU terminals, but on the O2 side, you need to find out which one is which from the other car. HT - N connector pin 8 HT - Battery (+) O2 - M connector pin 6 O2 - M connector pin 13 HT is connected to a non polarity heating element, so either way's connection will have no problem. But for O2, one is getting bias voltage from the ECU, another one is signal output to the ECU. This 2 must be connected correctly. [/QUOTE]
