4-wire o2 install Question

[BBY1104]

I am thinking about getting the cheapo 4-wire o2 sensor. I know there are 2 white wires and 2 black wires on the new one and the wires I will cut for the old one. Does it matter which white one goes to the other white ones and the same for the black? If so has anyone done this fix and could I get some pics or some advice in helping me to identify the correct wires to connect?

Thanks

There are so many options. Get a cheapo Ford 3 wire one and STFU.

I just want to know if there is any difference in the white wires, but I will just see If I can figure it out myself

there should be no difference in the whites. Just cut and splice.

I wouldn't use a 3 wire sensor in a 4 wire car, you want to keep the same # of grounds. the 4 wire sensor has a ground for the heater circuit as well as the sensor itself. Grounding is extremely important to the accuracy of an O2 sensor, and even though a NB can only read stoich, it's still just as important. Without that ground it's possible the heater circuit will cause noise or even worse, a ground offset in your O2 signal when it turns on and off. Neither are a good thing. ;)
