diesel: "What is the fifth wire on a wide band"
It might be interesting to notice that the so-called five-wire wideband sensor actually uses an 8-pin connector, and 7 of those pins are used. Two pins are attached to a calibration resistor that is housed in the connector itself. That's why you see only 5 wires traveling from the connector to the sensor.
You can find lots of info about wideband sensors if you google L1H1. The first link that comes up is especially helpful:

Thanks very informative looks like about $250 for the DIY wide band kit.
Ah, i see now wide band looks for hydro carbons on the rich side and oxygen on the lean side.
