I'm going to have to replace a broken O2 sensor on my old truck this week, and currently it has the stock single wire sensor in it. Is there any advantage to going to a dual wire sensor?? It seems like I had heard there was an advantage of some kind to using the dual wire sensor. If there is an advantage and I go with the 2 wire sensor what do I connect the other wire to??
