After I sent this inquiry, I found on the internet that the four wires should be heater power, heater ground, sensor ground, and sensor output. I am not certain how to discover which is which with an ohm meter. My assumption is that the heater wires would ohm closed, and the sensor ground might also be connected to these two, but probably not. How would you suggest I test the four leads to discover the sensor and sensor ground?

If you can identify the appropriate leads (should be easy with an ohm meter) you can use it. No need to use the pre-heater in our application.

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, Bill Bradburry
