O2 sensor wiring While wiring in my fuse/relay panel I just noticed that pulled all the O2 sensor wiring from my harness by mistake when getting rid of all the wires i didnt need. Could you guys help me tie these 2 sensors back into the harness... I know its 4 wires per side but could you let me know which pin location each wire goes to on the PCM connector. Thanks!

2002 Came with case ground or isolated ground. If i remember correctly pcm does not care what one you use just make sure you wire it properly for your O2 sensors.
