forgot to mention that when that wire is not hooked up the guage reads rich all the time

so black to black
black-green
white to white
green to black
so i have to change the green to black and the black wire to the blue wire right????
and how do u know what black wire to use?/

poison

The blacks do not matter. You can do either/or.

i got 2blacks 1 white i green on the stock and 2 blacks 1 blue and one white one the chart u gave me would require threee black's to work ???????

poison

Ok you have:

two blacks
one white
one green on the stock

and

two blacks
one white
one blue

where are you getting three blacks?

Those would color match, just match up the Blue with the Green if you are trying to splice them together using the stock connector plug.

my bad that is how i got it wired now the blue to green and the others color match but for soem reason my air fuel will not work now the wire for it was hooked to the white i tried that wire and the blue one but neither work for soem reason ?

poison

Air/Fuel should be hooked up to the Heater Control wire (A6). Since that varies in voltage which would tell you your A/F ratios.

blackccoupe

sorry but which is the heater control wire???? used to work when the stock sensor was in with the white wire?

poison

ORG/BLK wire is the Heater Control going to the A6 pinout. WHT wire is the O2 input signal (D14 pinout).

how come that wire doens't work now though it used to read the air fuel before i wired the new o2 sensor up ?

poison

Heater control is probably not hooked up correctly..not sure otherwise.
