Do you guys have a O2 sensor, harness side, Male plug you can sell me? I've got one that was melted at some point.

Added: I have not yet verified this first hand. See updates! I'm looking for a reliable aftermarket option for 90980-11178.
If it's the side with the pins (typically known as male) the Toyota part number for this connector
CORRECTION, the 1994 FZJ80 connector I believe actually looks like this:
And that Toyota part is 90980–11178 (female) and 90980-11177 (male).
Pigtails:
For 90980-11178 is 82998-12440
For 90980-11177 is 82998-12430
What follows isn't directly relevant but FYI.
The term "connector" refers to the plastic molded part.
The "terminal" is the little metal part that is crimped on the wire and there's a rubber "seal" or "insulation" that is also crimped.
Toyota part number 82998-12430 (this is correct for 90980-11177, too) is a 160mm long piece of wire with the terminal and seal crimped on. You can cut and solder on 4 new wires if you want. That's how the repair manual suggests to do it.
Note: I'm leaving the original OEM options because it seems 90980-10868/10869 are O2 sensors on some trucks.
If you want to do the repair yourself with all new parts and no pigtails this is a kit for the OEM (Yazaki) parts for 90980-10868: https://www.corsa-technic.com/item.php?item_id=992
This is the mating side (with the sockets or female), is Toyota 90980-10869 for the connector and the factory 160mm pigtail is 82998-12440 (this is also correct for 90980-11178).
The OEM for 90980-10869 is this: https://www.corsa-technic.com/item.php?item_id=895
This video shows basically how these connectors work.

Make sure you unlock the connector, there's a retainer in the connector that has to pull forward (the red part in his video, but on these it's black or white in they grey connectors). This step is missed often and unless you do this the next step will not work.
Then you use the flat terminal tool to push up the ramp and the terminal will pull backward. The terminals can be released from the connector with a very small, flat tool. A small jeweler's screwdriver might work if you're careful.
To install you push the terminal and seal in from the back until it clicks. Repeat for all four and then push the retainer back in to lock all the pins.
Here's a few of the graphics that are specific to the Yakazi types Toyota uses as to how the retainer locks should be released. How you do it depends and I'm not sure which is right on this one exactly.
A side view of releasing the tab on the terminal itself.

Moved these posts to a new thread. This is such good information that maybe we should pin it.

Is that all you could find?

BTW, I'm still double checking these part numbers.
I don't have a complete FSM for the 80 series to reference and when I went back on notes for what I used on my truck (2008 Tacoma) it uses a 90980–11028 and mates to 90980–11027. The Toyota pigtails (82998-12440/-12430) are the same.
These are also 4-way and are very similar. The difference is small but if you look closely these have different kind of guide slots on the side and bottom. It's more obvious on the female side.
This really only matters if you're matching one to the other. If you're replacing both it wouldn't matter.
These are the Sumitomo kits (Toyota uses both Sumitomo and Yakazi as OEMs).

Mike, I have a few O2 sensor connectors here, might get lucky if we look through my pile and find a pigtail you could splice in... or at least some pins to make things work for an e-test. lemmeknow

Wanted to bump this thread from the near dead and say thank you!
Bad O2 code myself, then found not only was factory harness side pin and wire corroded to zero, the other harness was melted and brittle too. Thankfully, all the nuts and bolts either broke or came off, except the damn O2 studs...
Check out the green on the wire and the plug, no metal pin left on the O2 side!
