I have an air/fuel gauge I wanna hook up. Any one install one before? I'm installing it into an eg with a b16 turbo setup. My gauge has a grey, red, and a black wire coming out of it. I figuerd red=power ,black=ground, and grey=02? correct? Which wire on the 02 sensor do I connect the gray wire to? What's the best way to connect it?

 

You just purchased a nice waste of money if you don't have a wide-band o2 sensor.

 

I know it's not accurate, it was given to me. I just have an empty hole where a gauge goes so I might as well fill it up with the gauge. It also looks cool!

those gauges are junk anyway, by the time it reads red its already to late!

It is your car, but why bother? If you can afford turbo, you can afford proper gauges. Hooking up a A/F gauge just because it looks good and you KNOW it wont give you any reliable results is stupid and is what some people would call rice. I prefer not to call it that...I just call it stupid.

When I did my turob install, I bought my gauge pods by what gauges I was goign to run, not oh **** I have a 3 gauge pod with a hole, better put a light show in there. Might as well put a neon in there..less hassle

 

put an EGT/oil/fuel/water temp/etc gauge int he empty hole. Not some fancy light show. An AF gauge hooked up to a narrow band O2 sensor is about as useless as ***** on a boar.

 

since it was given to you for free, sell it on ebay, make some money you can use towards a better gauge. im sure you already have a boost gauge. I personally have an EGT, boost, volt, oil temp and oil pressure.
