A/F Gauge - Where to tap?

SuperFlea · 11-01-2009, 10:47 AM

I want to install an air/fuel meter but what wire do i tap into? I know it's the 1st o2 sensor, but it has like 4 wires.

Any help is much appreciated.

uhh you are talking about tapping into the stock o2 sensors for a narrowband A/F ratio gauge. this is a total waste of time and money. narrowband gauges are worthless. they are just a light show

I would not recommend tapping into the stock o2 sensor harness. Narrowbands are not useful at all, but IF you are going to do it I would get a separate sensor and wiring harness for it.

Either way, not worth it IMO.

k well just to kinda help him out anyway even though its kinda unanimous that the wideband is a better investment...

how many wires go into the o2 sensor?...usually thats a hint into figuring out which wire to tap into

right it should, but some other vehicles have 5 wire, i wasnt sure what the focus had, but if its 4 wire there are 2 heater wires 1 ground and 1 sensor output...so what colors are we working with on your o2? or the op? or whoever is asking the question lol

it would really help you to read the whole thread, he mentioned above that he decided to get a wideband instead

Yeah, decided to get a wideband instead. I had an old a/f gauge sitting in my closet. Decided to give it a try. But, not anymore.
What do you guys think of Autometer?

focusmaniaczx3 · 11-01-2009, 11:05 PM

good stuff but you can probably find a AEM wideband setup for cheaper

edit: remember that you have to have a wideband o2 sensor with a wideband gauge. you cant use a wideband gauge with narrowband sensor or visa versa.

SuperFlea · 11-02-2009, 11:58 AM

Yeah, that's why i asked. didn't know wich wire

I'll look into AEM. thanks guys.
