No. The knock sensor is screwed into the block drain plug on the passenger side of the block. The OBD-II sensor has a 100Kohm resistance. OBD-I has a 4.5Kohm resistance. You either have to swap the sensors, or add a resistor in the PCM. The "lil chip in the pcm" is the knock module and the same one is used for OBD-I and OBD-II.
