No, the yellow wire at the buzzer Circuit #237 goes to the seat belt warning light in the center gauge cluster.
Circuit #237 has NO relationship with the the temp gauge.
Like I pointed out in your other tread, Circuit #39 is your power to PCB and gauges.
There is also a Pink/Black wire Circuit #39 at the buzzer.
That's where to check power at buzzer.
Now there is also another power source at the buzzer orange wire Circuit #40 but that is from the Stop/Hazard fuse.

OP,
I have NO interest in these e-bay listings...
Really good source for electrical on your year car...
These manuals are the same manuals the technicians used at the dealerships.
It's easier to help someone troubleshooting electrical problems when on the same page.

I'm out of ideas for your no power to a single gauge...
Have you gone through how your gauges are mounted?
Here is a link from Willcox Corvette.
It illustrates gauges that get insulated and what gauges are grounded.
Hope this helps...

Looking at this the ignition source for the temp gauge if you look at the printed circuit board for the gauges powers the temp gauge the fuel gauge the volt gauge and the oil pressure gauge. The clock is on its own power supply as it is a constant 12+. The 12+ for the gauges is only powered when the ignition is on. You must have a break in the printed circuit panel for the gauges or a bad contact on the printed circuit at the temp gauge. Since all the other gauges are working you have 12+ at the printed circuit contact. You may have a burnt temp gauge also. If you can get your multi meter and check the + stud on the temp gauge.
