does your car have 4 wire o2 sensors or 1 wire sensors?

if you have the 4 wire, then you have to get the correct wire or else it's not going to be correct.

I don't know which wire, because I have s sigle wire o2 sensor. However, I hook my up to the second o2 sensor. I am concern mostly about the 5 & 6 , most of the time they run lean.
