From my understanding the non-turbo rx7's (us ones atleast) do not come with a knock sensor. On the turbo motors it is from i have seen on the front rotor housing above the trailing sparkplug

Retards the timing when knock is detected.

No NA 13B's have knock sensors. The S4 13BT's knock sensor is on the center plate below the oil fill tube; the S5 13BT's knock sensor is on the front rotor housing above the trailing spark plug.
