Good or bad, you can get basic diagrams from "MyMopar:"

and I see those are somewhat muddied up, the 73 is in better shape
If you look at diagram "A", you'll have to then follow the wiring colors off to the "B" page
The top fuse is a bit of a trick and is the ONLY fuse wired this way. The tan is "dash dimmer" power coming FROM the headlight switch. The dimmer circuit obtains power from the tail light circuit. Once through the fuse, the orange feeds out "dimmed" dash light power to all the instrument cluster/ radio lights
The 2nd and 3rd fuses down, fed power from the red at left, get this power from the "in harness splice" taped up in the under dash harness, and comes off the ammeter circuit
These two fuses are the ones that are HOT all the time, not affected by the ignition switch. Fuse two feeds off to the right, to page "B".
On fuse 2nd down:
RED goes to the cigarette lighter, and PINK feeds the tail light circuit on the headlight switch
On fuse 3rd down:
One PINK feeds power to the dome light
The other PINK feeds the emergency flasher and brake light switch power
The next three fuses, 4, 5, 6, are fed power from the ignition switch and so are ONLY HOT in "ACC" or "RUN"
4th fuse down feeds a number of things, RADIO, backup lights, and turn signal flasher
5 feeds the heater
last one ??

I don't know how much different the 74 is from 72, you can download the 72 factory manual from here:

Here's a shot out of the '72 manual, looks to me like things did not change much:
