I just purchase an autometer air/fuel gauge and can't figure out where to put the purple wire. I also have a turbo timer that displays air fuel so I tried using the same wire it does (It taps right into a wire near the ECU) but as you guessed that does not work. Any advice or pics of an install would be great.

PS. I did try searching for this and the only post I saw had the pictures already removed.

THANKS

 

These are both pretty useless unless you have a wideband O2 sensor to hook up. The stock O2 sensor is narrow band and not very accurate, especially in the rich 10:1, 11:1 an 12:1 area where our cars run best.

 

I read on another post that someone connected the wire somewhere near the spark plugs?

 

If this helps..?

You may already have them and it may not address the "wire formally known as"..
