What ECU are you using? If your using the JDM PR3/PW0 here's, the pinouts.

It says B19 is your knock sensor, so maybe you just haven't wired it up (your stock B18A wouldn't have one). I can't promise that info's right, but that website is pretty reliable for information.
If your using an OBD I ECU with a conversion harness, the knock sensor is D3.
