O2 Sensor Help!!......

[turbonatormr2]

I have a Bosch o2 sensor that I am trying to splice into to connect to the stock sensor connector. Does anybody know which wires to splice into to make it work properly.

Here is what I have
On the Bosch sensor, the wires are as follows:

2 White wires are for the heater. 12v, it doesn't matter which is + and which is -
Black is EGO + signal
Gray is EGO - signal

On the stock 02 sensor itself the wires are as follows.

1 blue wire
1 white wire
2 black wires

Anybody. Here are some pictures of the two sensors. The black one is the Bosch 02 sensor and the grey one is the stock Mr2 sensor.

I have a single wire O2 sensor so I'm afraid I can't help you. What you might be able to do is dig into the BGB and find out what the wires are then use a multimeter to identify the right ones on your Bosch sensor.
