Good afternoon, do you have a circuit connecting the detonation sensors (2 of them) on the car listed above? Just on the driver's side of the sensor is a wire through the wiring harness lambda probe, and on the passenger side it goes separately!

Here is the wiring diagram for these. I am not sure I understand if you are looking for more but they are a simple circuit feed directly to the PCM on the same circuit.
