Need help with gauge.....

[180sx terror]

i have an autometer a/f gauge and cannot find the sr20det signal wire from the o2 sensor...i know where it is but what color is it? Ive searched frantically but cannot find the specific color. Call my stupid as long as you tell me which color...any help will be much appreciated!

being that its heated, you have a ground, heater power, and o2 signal. cant u test it with a wire tester, and i would guess that since the wires are red black and white that white is the signal-dont quote me on that

ill try that....but if i splice it into the wrong wire i heard it fries your ecu....i also hear its ok as long as you dont tap 2 at the same time...

White should be signal.
