A/F Ratio Gauge Installation - Diagram
Can anybody confirm If this Is an accurate diagram, In terms of Installing an A/F Ratio Gauge, In particular for the s4? What about the Ground Wire?
I prefer to tap Into the ECU rather than the O2 Sensor Itself directly. I do not want to disrupt the copper shelding.

silver go do this... find the 02 sensor wire plug... unplug it...
tkae the carpet out and the plate till u see the ecu... not stick one of the probes of a multimeter into the 02sensor plug...
put hte mulltimeter, set it on beep mode (or resistance)
take your other probe and start touching each pin until you see 0 reistance or you hear beep.
done.

That diagram's correct, but it's always a good idea to check as Cheers has described.
You can get power, ground and signal for the A/F gauge straight from the ECU. Use the ground (black) and signal (gray) as above, and for S4's use the very top left pin in that diagram (black with a white stripe) for the power. Dunno about S5's but it'd be easy to find.
