o2 Sensor harness

[Booster-Shot]

Alright, Ill make this short. I replaced my o2 sensor on my Laser only to find out that the other part of the harness was completely frayed. Where does this end of the harness lead to, and is it easy to remove/replace?

This is what Im talking about. If its too hard to find a replacement will I be able to just crimp another harness onto the exsisting good wires? Thanks

Go to a salvage yard, or check in the classifieds in here. I'm pretty sure you will find one in either place.

Its not so much about finding one(although that could turn into a problem if my pick-n-pull lets me down). I just dont know where exactly this thing connects to?

How would I go about taking it off?

Have you tried tracing the wires? In my car, the other side of the O2 plug (the non-sensor side) goes into the main wiring harness. I'm not sure how different your wiring harness is, but I would assume these wires run all the way to the ECU, which would be how reads your sensor's output. But try tracing the wires back and if they disappear into a wrapped bundle of wire (either by electrical tape or wire loom), then your best solution would be to repair it.

Cut off the frayed part, so you have clean wire ends, and solder it back together (you might need to add some extra wire so that it can still plug in). I wouldn't recommend crimping as they have a good tendency to come apart.

Yeah, I tried, it seems like it just goes into a dark abyss.

Then it probably goes into the main engine wiring harness which goes through the firewall.

Just try and solder it back together and you shouldn't have any problems. Just remember to cover the wires once you're done fixing it that way it doesn't get frayed again.
