I just put in a new Bosch Oxygen Sensor in my 1989 964. In my fuse box their is (R44) catalytic converter monitor is that a relay that fits in that spot for the Oxygen Sensor. Vernon.

My car doesn't have a relay in that spot either. It is not related to the oxygen sensor, instead it is related to a catalytic converter temperature sensor that most 964s are not equipped with.
