wire your knock sensor to B19 on the nonOBD PR3 or PWO ECU.

You should ask that question by listing what ECU you're running with the setup. If you're using a stock <U>DOHC</U> VTEC ECU, regardless if it's OBD-0, OBD-1 or OBD-2, they all look for a knock sensor. If you're running some jenky way using a LS or stock SOHC ECU with a MSD box to activate VTEC, then no that ECU doesn't look for a knock sensor.
