I need electrical help.
Also, pick one thing that does not work and trace it end to end. Often, that will magically fix another problem, or lead you to issues with another problem.
You said your hazards don't work, and the fender turn indicators. But to the turn signals work? Do the FRONT signals work? Do the brake lights?
If the front signals work, that means power is getting through the harness, and that means (for that circuit) that the bulkhead connector is OK. If they are not working, and given the other problems, the bulkhead connector IS A good bet. Actually, you should check it, anyway. Pull the individual connectors off in the engine bay and inspect.
The hazards, remember, you have TWO flasher units, one for hazards, one for turn. You have to find them. If you get into the wiring diagrams in the 73 shop manual, and go onwards AFTER the diagrams, you will find charts there for drawings of connectors, and those give you LOCATIONS.
Here is an example from part of page 8-168. This is showing "CI" series connectors, which means "Connector, Instrument (panel)" and notice that each one has a hint on where to find it, and is drawn so you can see the wire colors you are looking for, and the shape of the connector. Of course you would hope that the hazard one actually has a flasher plugged into it, but you never know
