Thanks a ton! Exactly the info I was looking for. Thanks Frenchy as well.

May have answered my own question. Seems likely it is the temp sensor, I just figured it was elsewhere since I don't remember removing anything from there. I already have a new sensor, so I'll see if it fits and matches up to the harness. Temp gauge wasn't working when I bought the car, so is it possible it was missing to begin with? I find it strange I didn't notice anything missing when removing the harness. Still thrown by the whole thing, so would love confirmation from someone more knowledgeable.

Hey everyone, I'm new to the forum. Currently rebuilding the vg30 out of the 93 pathy I bought last May. While reassembling everything I noticed a threaded hole in the front of my left-side head with nothing in it (see photo) that I somehow didn't notice until now. Looking back at some photos from the teardown, it looks to me like there wasn't anything there in the first place, but I want to make sure. It's possible the machine shop removed something for cleaning and it didn't get reinstalled. Any ideas if anything's supposed to go here? After searching some parts diagrams the closest things in that area seem to be threaded plugs or a coolant temp sensor, neither of which seem right. Let me know if more info or better photos needed. The hole in question is in the center of the photo, above the water pump.
