Default Problems installing air/fuel gauge on 92 legacy

Hey guys, i just wired power wire into the ignition so the gauge turns on when my ignition is on, as well as a ground wire.
Then i wired the third wire into my O2 sensor. There are 3 wires running into the sensor, i wired it into the black wire. I was told to tap into the signal sensor wire BETWEEN the PLUG and my ECU. I did that and it still doesn't register on the gauge. Did i use the wrong wire?
If anyone has any suggestions please let me know.thanx Ryan

Black is ground, white should be the signal wire.
