Tach and other electrical problems

I have a 95 7.3 and my windshield wipers stopped working randomly, my ac/heat blower doesn't work, and now whenever I turn my AC on my tach stops working, if I turn the windshield wipers on my tach stops working and the windshield wipers don't work and there's a whining noise from the passengers side kick panel, the headlights also stopped working and when I turn them on the tach stops working. My blinkers do work but the tach bounces with the turn signal, I think I have a bad ground or something. Where should I start first and is there any good diagrams that can help me find the issue?

I'd highly recommend an electrical & vacuum troubleshooting manual for our trucks. I picked one up off amazon for around $40 and it's worth its weight in gold.

whining could be a vac leak and main line is run through passenger side
