Does anyone know if the 02 sensor wire goes straight to the ECU like the knock sensor wire does? Reason I'm asking is the wire to my O2 sensor is bad and I just want to run a wire straight from the sensor to the ECU like I did my knock sensor wire, instead of unlooming my harness. I looked at the BGB on celicatech but that is the usdm version and my O2 sensor is a single wire and that looks like its 2.

Oh and yes I replaced my O2 sensor.
