No power to instrument fuse 66 dart

The inst fuse is a "trick" circuit. This is the ONLY fuse that is "downstream" from something else

The power for the dash dimmer comes FROM the tail / park circuit in the headlight switch. Through the dash dimmer, and out on the tan wire, it then goes down to the fuse panel, through the inst fuse, and to the dash lamps on ORANGE wiring

So the tail circuit has to be intact and the fuse OK
The light switch has to be "on" either park or head
The dash dimmer has to be turned "somewhat" to the left..........

and only then will you see power on the inst fuse

I see that now. So I'm more confused as to why my gauges have stopped all idea sudden.

I realized that now. I've turned on everything, and checked the test light and it is getting power, my dash lights are working, headlights are working tail lights are working, but both gauges are not. The circuit board, instrument cluster gauge are new maybe 6 months old, i dont see anything on there that is suspect do you?
