So I got my auto meter a/f gauge. I have to hook up the ground, the accs. 12v. and the signal wire which is supposed to hook up to the signal wire from the o2 sensor. Ok, Which wire in the o2 sensor is the signal wire? Color?

I have a 94 accord ex. Thanks for your help.

 

[white accord 94]

black is ground, purple is o2 sensor, red is 12V power source.

I know what the cables on the guage are for. I need to know which cable, what color, is the signal cable on the oxygen sensor. Thank you

 

[white accord 94]

its white on the o2 sensor.

white wire , its the white wire
good luck ,
dont splice your wires to the point where you have to replace yoru 02 sensor
that will cost you about 150 bucks,,
white wire

Ok, I got it. I hooked it up. But, the gauges just switches back and forth, even when I am full throtle. And then, there is like 6 leds lit up at the same time, so if it was in the center it would still cover part of rich and part of lean. Wtf. does anyones elses gague at this way.

 

[Chirp4thGear]

thats the its supposed to work
but when you floor it,its supposed to hit into the rich
and when you are cruisin or idling its supposed to bounce back and forth
cause your fuel system is always correction the mixture

and you should read the manuel to understand its function
it all explains it right there

right now you should be running normal since you dont have any force induction or fuel upgrades

I DID READ the instructions. And I know the computer is always adjusting the mixture. But what I am wondering is if its always supposed to be so many leds turned on at the same time. Thanks

 

[Chirp4thGear]

yeah man thats perfectly normal
when i hit vtec in my car
all the green side of rich lights up
and when its just driving normal
it bounces back and forth
with like 2-3 led's lit up

which wire is it on the same car, but o nthe ecu
i tapped about 3 wires i was told would be it, but none of them worked.

ken

 

[Chirp4thGear]

did you try it on the 02 wires above the harness?

i know of a friend who tried to tap it into his ecu
and he fried his black circuit box

 

[sakdpimp]

What I did is to took the wire striped a little off the end and stuck the wire in each opening with the car on and when it was at stioch I found it.

k, ima think ima just wire it to the white wire on the o2 sensor itself...
