Autometer A/F guage hookup

[SuperDakota]

This may not b the right place to ask this but i didnt get an answer in the other one.....Where do i hook into the O2 for an A/F guage...What wire ... or can i go off a pcm wire ....That way would b best i think ....Getting a total reading ...anyone have a wireing code for the PCM......Thanks guys

if you have just the narrow band af then i believe its the white wire on the o2 sensor. but it will only give you a light show...if you have a wide band o2 sensor then use the one that it is calibrated for.

if you have a narrow band dont waste your time.

i tapped into my pcm wiring for my narrow band, though i forget which wire!!

i agree with the others... skip the light show, they are useless. if i can make a suggestion.... put in a trans temp guage. sure, there's an idiot light for it but it's calibrated to come on way, way too hot. if you see that lite, your trans is toast.

[blackknight]

i tap into one and nothing happens i tap into the other one and the green light stays on

green light stays on for a minute or two, as the o2 heats up the meter starts to work, give it about 2 minutes of engine running,

I connected mine to the trucks wiring harness, I don't remember what color and I can't look under the truck now, I'm at work

Every time I've seen two white wires, they were just the power and ground for the heating element. what are the colors of the other two wires? one shold be the signal and the other will be signal ground. Try looking at this link, they have a couple of common wire color legends.

Ok, I crawled under my truck, and I did connect it to the O2 sensor not the harness, It is connected to the only BLACK wire, hope that helps, Gwyn

[blackknight]

ok yea because two are white one is black the other is grey

[blackknight]

i plugged it into the black and got a light show now i just need to fix that ground to the engine block everybody is sayin that should fix the light show and get good accurate readings

What ground? never heard of that? at steady cruise speed it runs pretty steady, only a little jumping,
