My engine came with the O2 sensor installed.  I would naturally like to
use it because of the cost of sensors.  However, the instructions for
the EM-2 seem to require a one wire sensor which has the body grounded.
The renesis O2 sensor has 4 wires!  Black, Black, Blue, and White.
I have not been able to find out how these wires connect on the car, so
I have no idea how to hook it up with the EM-2 if that is even possible.

Does anyone have info??
Tracy, what say ye?
Just in case, the sensor is inscribed:

MCG
N3H2
Denso
04F12
-4211
Thanks,
