Cluster fun.
Cut and pasting from the other '73 wiring threads
This is the basic power feeds for a '73 Duster unless it has the fleet type alternator or rear window defrost grid.
Of the 7 fuse slots:
2 fed from the main splice are always hot.
3 were fed from the key switch.

The written list of what the fuses are for is on pages 8-114 and 8-115.
FYI.
There's a 1974 Master Tech filmstrip and booklet about wiring diagrams. It covers the new style of diagrams introduced in 1973 and explains all of the wire codes. pdf version here: Browse MTSC by Model Year – 1974 – MyMopar
One topic not covered in that booklet is keeping track of the circuit. It might be covered in the filmstrip, I forget. It was covered in the 1960's version of the booklet. Basically it comes down to tracing or drawing just the circuit you're interested in. I think that's even more true on these later diagrams.

Once you know the year to look under you may want to go to the mymopar website to see view them.
