i finally needed to get new o2 sensors and i got them from the Group deal. are the maxima's equiped with 2 wires per each o2 sensor or 3 like the ones i ordered? they are black red and white on the walker o2 sensors, i havent gotten a look under the car yet, so can anyone tell me how many wires does the maxima have for the o2 sensors.

 

4 two white 2 black
