    where is the o2 sensor going to be fitted on the exhaust? N/A 16v's have it on the primaries and is a sinlge wire. GZE and 20v have it on the secondaries and is a 4wire (but 3wire will work). Because on gze/20v the placement is quite far back (just before the cat) it needs to be self heated.

    2 of the wires on a 3wire are just 12V and ground, and a sinlge wire for the sensor.
