Help identifying vacuum hose port and wire harness plug (2 Viewers)

[JAX 1988 FJ62]

Good morning! I’m in need to some help from the experts here. Finishing up the last few things from swapping 3FEs and there are still two items I cannot remember.

I have a vacuum hose part on the passenger side below valve cover and just in front of the oil filter. Can anyone tell me where this should be connected?

Also, there is also a square yellow wire harness plug on the passenger side that I don’t see a home for. Anyone remember off hand where that goes?
Thanks!

not certain but the nipple looks like the fuel return, does the other end go to the fuel rail?

Yes, I believe you’re correct. Runs across to the drivers side. I believe that’s the fuel pressure regulator?

Any clarity on where that return goes is greatly appreciated! Thanks!

should be a rubber fuel line attached to a steel tube that runs along the inside of the frame, not inside the frame, the inboard side of the frame

The electrical connector is for the O2 sensor on the inner exhaust pipe.

The metal tube is the fuel return line, here’s a picture of what it looks like assembled:
