Correct on that. All the warning lights and fuel guage get power from that fuse.

Yes that's the puzzler. In your original post you mentioned a short in the sender wire. A short to ground would/should turn the temp light on any time the switch was on. That's got to be looked in to a little further.

That's a fact.

It's pretty simple; the bulb has power anytime the switch is on. The E-brake switch and brake pressure failure switch are the grounds to turn the bulb on.

I'm afraid that's going to be a definite.

Looks like the pink with black stripe wire, from the ign switch powered guage fuse, is the only hot wire for warning lights and fuel guage.
The other lights and indicator bulbs get power from their related components. They are grounded in the dash and getting power turns them on. Where the warning lights have power going through them then a switch or sender provides the ground to turn them on.
Other than the temp sender wire issue you mentioned (and maybe including it) it's looking like something is wrong with the printed circuit or the plug-in/connector going to it.
I've had to clean and tweak/bend the terminals in the PC connector so they would make better contact. I've put tape on the edge of the hole in the cluster so the terminals in the connector would make tighter contact with the PC.
Good luck for now and keep us updated on any findings.

Little more: That new PC needs looked at close and compared to the original. All the contact spots on the flatwire in the PC need looked at to make sure there's no excess plastic causing them to be insulated. Bulb sockets also need looked at close. Brass contacts, on sockets and PC connector, get old and stiff (lose their spring) with age.
Good luck again
