I am trying to install A/F gauge , i need to tap to the o2 sensor
these 4 wires are coming from my o2 sensor,
which is the correct one to tap it from ?

 

bump cause i would also like to know

 

The off white one. It is a little thicker than the other 3.

i tapped it off the white one but when it turns on it says rich with 1 bar there is that right?
or on the ecu what pin does it need to be at

 

if it is a P30
D14 WHT PHO2S O2 sensor
http://tech2.hybridgarage.com/..._obd1
the one in the pics looks wht/blu it is "back up power" in D1 position
you need D14 solid white
check the link it is sum good info

 

the ecu is a p28 and motor is b16a2 us

 

i recommend tapping it off the white wire off the o2 sensor rather then at the ecu.

 

does anyone have a pic of the layout on the ecu
to tell me wheres d14 on the p28 ecu b16a2 swap
i am searching everywhere

Thats how ive heard to do it.

 

found a pic ,
now where is d14. is it where it says c14?

 

ok i just tapped it off that c14 and my a/f just has 1 light its on the right on rich and it doesnt move from there .
whats my problem now?&gt;

 

anyone know why this is happening

 

Is the car running and warm? When it is cold it will just hold one bar in the rich somewhere. When it reaches operating temp it should start sweeping at idle and doing its thing.

the only CEU that is ABC is the OBDO
who ever made that is wrong i belive that only the C plug was for auto ECU so what is C14 is really D14 some one correct me if i am wrong
are you sure you did not tap the MAP sensor?

pretty much the basic rule i've seen for tegs and civics. It's the big white wire. Usually on the pin out closest to the passenger

lol dosent sound too smart to just grab what looks closest to passenger
b/c acording to that digram there are 2 white wire withen like a cm or 2

 

lol.. good info h-t

 

Try letting the car get to normal operating temp. After a couple minutes you should see it start to sweep.

Damn, I can't believe how hard everyone is making this. Question has been answered but that appears to not be good enough.

Very simple, look at the wires off the ECU. There will be 2 white ones but one of them will be thicker and more off white in color, that is the one you want. Just take a look at your harness and you'll see how easy it is to locate. Lets not make this more difficult than it needs to be.

 

he got it to work
