I noticed my SR RedTop had the wrong O2 sensor

-Instead of the Titania (Skinny) o2, it had a Fat o2



So i got the correct skinny o2, but wiring looks off;;;



[[[UPDATE]]]].......................................


Correct wiring for 62 ecu and skinny o2 is;




harness------skinny o2

Brown--------red
White---------black
Black---------white

I know someone has to know something..Zilvians !!!!!!!!!!!

Last I did this, I thought the polarity doesn't matter. Find the signal wire and connect that first, then wire the other two which ever way.

*I think.

Come on guys, i need me 02 to work correctly..

yea but these are all guessing....

1st. thread says that the White on sensor is signal

2nd thread says that the black is the sensor signal..


Thanks anyway

I did something along these lines.

I had a hard time looking for this info as well. I'll check my wiring whenever i get a chance and post pics.

Can anyone post pictures of there redtop o2 plug and sensor wire colors?

[ReLiC]

did you figure it out? i'm trying to wire mine up as well.

Where are you grabbing the 12v from? Is it ok to just grab it from the maf power?

Yea the pic is correct

On the red top sr its

harness------skinny o2

Brown--------red
White---------black
Black---------white


The brown harness wire is the 12v sourse

*on the skinny o2 sensor the black wire is the signal wire and white is ground

heres what I usually do. Go to pep boys and look through the oxygen sensor boxes until you find all the 1-wire oxygen sensors. Buy the cheapest one, usually $12 or $14.

Now, you know exactly which wire is the signal since there is only 1 wire. Install using the single signal wire and never worry about this again. If you put a voltmeter on the wire, it will flip from 0.005Volt - 0.985+Volt when working properly.

Im pretty sure pepboys doesn't have a large selection of titania o2's
