    have done a b16A 1st gen PR3 ECU mod on my civic. Need help knowing how(where) to wire the knock sensor.
    The schematics that I have do not show the sensor. The wiring pinout calls for pin B19. I am told it is a shielded wire as well.

    Do I connect the one leg of the sensor to B19 and the other leg to the logic ground and then where do I terminate the shield connection. The CYL pos or TDC sensors show two ecu points plus the shield going to the logic ground. The oxygen sensor shows shielded wire with one termination point at the ecu, the shield going to logic ground and the sensor itself being grounded.

    do you know where I can get a schematic that shows the sensor and connections or at least how do I terminate my knock sensor?

    Im pretty sure your knock sensor only has one leg on it that goes to b19. The shielding needs to be grounded, what you can do is take the shielding and solder it to another wire and run it to a ground point. I dont know if it goes to logical ground but the jdm harness actually has the knock sensor shielding crimped to a red/black wire that goes to a groud on the motor.
