O2 wire help!

O2 wire help!
So I had a guy torch off the bolts to the pre cat and some how he managed to rip out the O2 sensor clip off the engine harness....
im trying to splice the sensor back on but I dont know what wire coresponds to what wire on the O2 sensor,
I was hoping some one could shed some light on this
its the rear primary o2 sensor
Thanks!

Thanks for the link but it doesn't say which wires corresponds with which wire, it just shows where it is and to plug it in lol
And of course the front sensor has different color wires so that doesn't help either

should be under ecu or power mngmt
i got the colors at work ill look and post

Ah thanks man, I finally figured it out by putting a volt meter on it.
I still cant get the CEL to go off though, i spliced the wires together and the engine harness side has the same voltages as the other sensor so it should be fine, but its still triggers the code.
It is cool to be able to see the approx. A/F ratio based on the voltage, im hovering right around 14.7 ( .4-.5) so even with no sensor input im still where i should be. I wonder if this would cause any issues?
I also wonder if i could just splice the first sensor signal to the second one at the ECU to get the light off

I dont know how he managed to break it, He never took the sensor out, its the sensor in the manifold, those were left alone. But in his attempt to get the pre cat off he ripped the clip off the engine harness so the connectors were still together but dangling attached only to the sensor not the engine harness.
