John from J&S described the signal to me. Doesn't look like you could use it with the S-AFC

The output from a knock sensor is an audio signal, like from a microphone. If you connect one to a set of amplified headphones, you will hear the engine running, without the exhaust noise.

The sensor on the 350z has a low output level. You might get a volt or so peak to peak with heavy knock. The frequency varies from 5kHz to 10kHz, depending on the cylinder bore diameter.

you probably have the wrong wire......several wires have the same color coding......verify the pin number is correct on the harness........white wire, pin 15
