Problems with my A/F gauge...

[mourningstar]

So I had a shop install my A/F gauge.
Red is power, black is ground, grey taps into the O2 sensor wiring.
I read on here that I was to tap in to the wire on the ECU side that was OPPOSITE to the black wire on the o2 sensor side.
My gauge now reads two bars of red above the Lean level, and it doesn't move. At all.
Is it supposed to move?
I know for a fact I'm not running that lean.
Was what I read incorrect?
I am all sorts of confused, and I'm hoping this isn't damaging anything.

Any help would be appreciated. Thanks!

It would help if we knew which model Hyundai. First, make sure you tapped the O2 sensor closest to the cylider head, not the one after the cat. Second, make sure you tap in to the correct wire. On my '01 Tib, the wire is yellow. The Bosch 4-wire O2 sensor should have 2 white wires for the heater, a gray wire for sensor ground and a black wire for sensor signal.

I have a 2000 Hyundai Elantra. Auto.
They tapped into the o2 sensor right on my header.
I believe the wrong wire was tapped.
As soon as this rain stops, I can go out and look.

Thanks for the help though.

On a '00 Elantra, the wire should be yellow.

On the ECU side of the o2 sensor, I have a white, green, orange w/black stripe, and a pink-ish wire. I do not see a yellow wire.

try the ornage w/ black stripe. On my 97 Tib fx its the black wire. The lights will actually move back and forth quite a bit.

What color is the wire from the ECU that connects to the black O2 sensor wire? Your O2 sensor has 2 white, one gray and one black wire, correct?

[mourningstar]

Yes.
The wire on the opposite side of the black wire was white.
This was the one that was tapped.
