Well I wouldn't be asking this if I had my hayes manual. I threw it out because it sat out in the rain overnight and got ruinned. So could someone post a pic or tell me how to tap into the O2 sensor at the ECU to Install an Air/Fuel Gauge on my S5 Turbo II? Also what do most of you guys use to hold your A pillar pod in place?
TIA!
TIA!

It will only tell you there is nifty looking lights blinking in your face.
That's a really ignorant statement...
I completly disagree that an A/F gauge on the stock sensor is "useless" and "worse than nothing at all". If you understand what they're displaying and know how to interpret the readings they can be very useful.
Most people who critisise A/F gauges are talking about their ability to do something they were never designed to do, i.e. accurately read full-load mixtures.
From now on don't post in my threads unless you make yourself usefull.

havnt posted in so long...whoa cool skin.
anyways..... not to be biased but iceblue is right. you probably have a narrowband AFR gauge.. which is useless. itll just go all over the place and be "blinking lights" like what he said. they dont give any sort of accurate reading. at ALL. the only way to have some idea of your A/F ratio is if you have a wideband AFR gauge. ppl buy narrowband ones and regret doing so when they see what it does when its plugged in.

I didn't specificly pick and purchase the gauge it came in a pod that I purchased.

Throw the AFR gauge away or sell it to a civic driver. It wont do you any good. Go buy a wide band AFR gauge it will require a wide band O2 and plug right in.
Yea the new board is
