I want to install an air/fuel gauge on my Koup but I dont know to which cable of the O2 sensor it goes.

Can someone tell me the color of the right cable?

A wideband o2 sensor comes with a bung that you have to weld onto your exhaust . It goes on a 35 degree angle and has to be welded between the first o2 and the cat

shouldve gotten a wideband instead of a narrow if you were going to get a a/f gauge at all.
pretty sure you can get a narrowband to work on our wideband system but not sure which wire you need.
I'd guess you could look up the wiring diagram on kgis and find the signal wire, which I would assume would be the wire you need. it'll probably have the color on there too, but will be abbreviated (like brn for brown, or brn/gry for a wire which would be brown striped with grey.
good luck!

Might as well have gotten a voltmeter or some other worthless gauge. You won't be getting accurate readings off of the stock O2 Sensor. You are pretty much just going to have dancing lights that mean nothing.

What is your need for a A/F gauge? Turbo? Other heavy engine work? If not, save your money and return it.

Not only does it show a/f mixture.....after you can fill your BONG with marijuana and get high!!! I would use a BUNG though! Lmao that's funny!!

It just that I have the gauge in other car and I think It would look nice on the Koup.
Ill eventually would get a Pyrometer or/and WideBand, buts that when I get the NOS!!!

Fixed.

Exactly what croc said. But I would definitely get an actual wideband. It's not a bad 1st mod, 'specially if your going to do work on the engine. You'd be suprised how many drivers run boosted cars without a wideband, get it now then later.

Wideband or not it is almost pointless unless you wanna watch it for fun.:rolleyes:

Without any software to remap the stock ecu's A/f ratio it serves no purpose
