Instrument panel gremlins
Has anyone else fought the gremlin of loose wires and improper readings on the instrument panels of the '92 Bonnes? I first noticed that the water temp guage was showing very cold or very hot, depending on whether the fuel guage was showing full or empty, respectively. Then the whole IP started to flash and the dinger to ding, like it does on start up. I have pulled off the surrounds and bezels and removed the IP, cleaned it and reinstalled, with no improvement. I have clearly determined that the main connector, behind the speedo area, can be moved slightly back and forth to cause the loose wire symptom. So I need to figure out which wire or wires are not getting solid connections. But I'm not sure that will fix the fuel and temp cross talk. I think that may be a ground mess up. Any help would be greatly appreciated. Especially since I just ran out of gas, two blocks away, because the gas guage won't read low until it is nearly empty and it reads completely empty, when it is completely full.

I think you're a prime candidate for this:

Just had one last week. The member was apprehensive, but found it to be a rather simple procedure, and it solved his problems.
If that doesn't do it, go after the ground bus locations under the carpet at each front door sill. They're known to corrode as well. Check for moisture under the carpet while you're there.

As you've already had the cluster apart, this part of the procedure may be the most important part of it, for you.
I had a similar problem on a '93, removing and cleaning didn't solve it. Soldering several of the the larger connections, like where the boards connect together and some of the larger components are installed, solved the problem. You may not be able to see where the cracks or bad solder connection are.
17) Look for cracks in soldered connections, especially where ribbon cables plug in. I was lucky and found none; my flickering displays were just due to oxidized connections, and the process of unplugging and reassembling was all that was needed to restore a solid display to the dash. If you find an obvious crack, use a hot pencil-tip soldering iron to melt and reflow the solder where necessary. Be careful here; a replacement cluster can run a few hundred dollars, so if you're not comfortable with pinpoint soldering, paying a pro for the repair at this point will be a lot cheaper (since you've gone to the trouble of pulling the board yourself).

Hoping someone with a 92-93 manual can check the ground in the cluster gauge schemaitc tonight and we can then trace back exactly which ground and where it gets the original ground from for you.
