66 fury 2 wagon

Sounds like another job for the Factory Service Manual.

Check the wiring, globes, connectors (clean and tight), just a logical progression and the problem will (or should) be found then repairs as necessary followed by happy motoring.

Your wagon is 52 years old - was probably expected to be scrapped within 5-10 years. I wish you all the best for a quick resolution of your issues.
 
FSM wire schematic.
What do the non working circuits have in common? How do they interact with each other? Where is the power feed coming from? Where does it loose power?
Print out the schematic and color the non working circuits as the schematic wire colors are called out. Once you understand the relationships between them it should be much easier to trouble shoot. A test light is your first friend, but don’t poke holes in the wires. Start at the beginning of the circuit (fuse panel) and work your way through the system.
