I Got a narrowband from a friend who sold it to me for like $10 so i couldn't resist. Where do i connect the 02 sensor wire to? It would be the purple one, but which wire? do i use the one that goes to the ecu, If so Which wire?

I have a 95 Ls integra, and it s a Autometer guage.

i would check autometer's website to see if they have an instruction pdf file for you

Which wire is for the 02 sensor? Not on the gauge but on the Car.

What do you hope to gain from installing this gauge? A narrowband O2 sensor is ONLY accurate at 14.7 which is where you want to be running during normal cruising or idling. For tuning wide open throttle operation you want to be anywhere from high 11's to low 13's depending on a number of factors, the narrowband can't help you there, at all. It can tell you if you are higher or lower than 14.7, but not how much.

If you still want to install it, I'd cut into the harness for the sensor itself, between the senor and the harness clip for the primary O2 sensor.

IanB, im not tuning with it. I just need to know if im leaning out or not. More or less its a light show. Something telling me that im lean or rich is better than nothing eh?

You can be well below 14.7 and still be dangerously lean, a narrowband won't help you with that. You need a wideband to get any useful info unfortunately.

You wanna buy it for me? I don't have the cash right now to drop for a wideband.

I had to pay for mine, you can pay for yours, lol. Save the $10 this would have wasted and start saving.

Tap into D14.
