Default Coolant sensor (gauge) wire location

At some point during my new harness install I removed the lead that feeds the stock coolant temp sensor. I have not removed the stock harness yet, but I can't seem to find that connector in the bundle I pulled back. The only harness bits I actually removed iirc was the short extension for the injectors, since it unplugged and was easy to remove.

So my question is where does the temp sensor gauge wire enter the harness? I labeled everything I pulled back, and it's nowhere to be found. This leads me to think that it was somehow included in the injector harness, but that headed away from the temp sender under the hood, and is currently buried in my storage area and therefore not so easy to just have a quick look at. There is a black/blue wire in the plug for the injector harness, but I don't want to just start poking wires in there to see if that's the one.

Thanks.

Mine's in the same harness that comes from fender side. It has a few plugs on it. 1 to TB, 1 to coolant sensor and another one I cant recall off the top of my head.

IIRC it goes back through the fuel injector harness. From there I dunno.

Ok cool. There is a matching color wire in the inj harness plug (black/blue), so I'll run it there and see what happens.

Thanks guys.

Edit: Thought I'd follow up and report that this was the correct wire. I jumped over to it from the sensor and the gauge works again.
