Today went to replace my O2 sensor and was surprised to find a 5th wife in the loom before the 02 connector. I can't find the other half of it, but I'm guessing to goes some where? doesn't help that the insulation is gone.



Dirt, snow, grass, or ice if it's a loose surface I'm going sideways and happy about it.

See the diagram in the site thread below.

Click for GVR4 thread

It's a big fanout sheet for 4g63 type wiring. Pins with the little circles drawn around the wires, for the 02 sensor and the knock sensor are a shared shield setup; open an unattached at one end, connected at the other, but not part of a circuit - just noise/RF rejection, likely only could be causing by radios/plugs/etc.

I just build a little harness to replace my current one should anything in it go bad, and I had my hands on those wires first hand. The other guys before me, nailed it!
