The Focus us a 4 wire o2 sensor correct? Any way im installing my Auto Meter a/f gauge and cant figure out whats the correct wire to tap into. In the install sheet it says connect the purple wire to the o2 sensor high signal? Witch one is that?

for mine, i used the black wire, if that doesn't work for you, just keep trying, i'm sure you will hit the right one, and you won't do any damage as long as you don't run it like that for to long, some people say the white wire works, but some say the black wire, i used that black and it's been working fine for like 10 month's now!
