02 sensor other plug
On a 84, 85 911, the 02 sensor has two plugs. The big plug measures the tiny amount of voltage to measure the oxygen in the exhaust. Then there is the two prong plug. Can someone tell me what this plug does. Just cant find it. Nick.

Off the top of my head, I would say it's for heating the sensor so that it operates correctly faster.
