Photo 1 looks like seat belt body connector.
Photo 2 is seat belt buzzer.
Photo 4 is map lamp switch.
Go to mymopar and search for 1973 Dodge chassis service manual and look at connector chart on pages 8-168 thru 8-172.
Dodge Dart and Plymouth Duster have identical electrical diagrams.

THIS!!! If you don't have the 2 manual volumes, run over to MyMopar and download them. Not all the connectors are there, but most.

Take stuff that doesn't work one at a time and repost here, EG brake lights. The brake light switch should ALWAYS be hot and gets power from one of the fuses. So get power to the brake light switch. When pressed, the switch feeds power TO the turn signal switch, usually on white. So you can heck that at the TS switch connector at the steering column. With the column switch centered, and the hazard switch off (wiggle it they can get intermittent) brake light power should then be routed to the left and the right turn signal filaments.

Post back here as you progress and guys can answer your questions as you go.
