Lighting problem
Something I've REALLY been pushing lately is "do you have a shop manual?"
There's one you can download free right here:

Index to wiring starts on page 8-144.
About 8-151 is the instrument panel wiring
The only lights -that I'm aware of- that are not fused are your headlights. These are "fused" by means of the breaker that is built into the headlight switch.
But most power "from" the fusebox either comes from the "battery" feed (hot all the time, like stoplights)
or it comes from the ignition "accessory" feed--hot only in "run" or "accessory" like the radio, heater
HOWEVER it appears to me that the "instrument" fuse comes directly from the headlight switch, so it may be getting it's power from the main feed to the headlight switch and through the switch mounted breaker
(Notice wire E1-18T) (tan) coming down from the headlight switch TO the instrument fuse. THIS IS THE POWER INTO the fuse
This is a clip from page 8-151
"MyMopar" has simplified wiring diagrams that are completely different from the shop manual, but are sometimes easier to follow:

Page 8-127 gives you the functions of the fuses:
And, I REALLY had to look, but here's a photo of your fuse panel from page 8-69
