knock control

I did a JDM S5 swap on my S4 TurboII I cant seem to find the wires that go to the S4 box that says knock control. I am wondering if these are diffrent on S4 and S5? and could someone please send me pdiscription or pic where the wires that go there come from?
Thanks
Mike

my s4 has a knock sensor. Um, the knock sensor for the s5 was a 2 wire, whereas the s4 was 1 wire (?). My s4 has a 1 wire, thats all I know so the s4's DO have knock sensor.

Im not talking about the sensor Im talking about the module that says knock control is on the pasanger side near the ECU.

The S5 knock control box is built into the S5 ECU.

All Turbo models had knock sensors.

Hence, S4 turbos had knock sensors.
