mods help out not sure were to put this (ho2s wiring)

[Rance]

i am installing air fuel ratio gauge and need help as to witch wire on the ho2s harness sends signal to pcm. i know our sensors are four wire sensors. I used an volt meter to try to find the right wire, and found that one wire is battery voltage ,the other is ground , the other two both had voltages between .1 and .5 (purple wire was .17 and orange was .30). also this is the sensor right before the cat and right after oil drain plug if ypur standing in front of the car facing engine. any help would be greatly appreciated, those of you who are running air/fuel gauges. thanks

mods if im in the wong area please re-direct. thanks.
