Losing switched power and other #$%&^# electrical issues. HELP!

Pretty sure I found it. Now if I can just figure which wires go where. There are a lot of spliced wires in this spot and aren't factory colors. Only one is power, and I know the alternator b+ goes to that.20170730_111334.jpg 20170730_112006_001.jpg 20170730_113550.jpg 20170730_115836.jpg
