Well man its like this... not everyone looks at wiring diagrams in the real world most are wanting a quick place to look and honestly a suggestion of a part to throw at it who really knows how to trouble shoot? as for myself I am a retired ASE master tech and also was TRAINED in Fighter jet avionics by the Air force. I served in Iraq 15 years ago so it is all fresh in my memory and basically electronics ,once you know it it doesn't change. The last thing ill do is argue in here... I will stand up for myself and have. But, my car runs and my headlights work. Now in real life my experience has been that the headlight switches burn up. I once drove a 71 Pontiac home with my hands under the dash holding the wires to where the lights stay on. That same switch is the same type used in Mopars and just about everything else. BUT I digress, no one wants to offer an opinion to be jumped on and attacked buy some anonymous internet poster / troll hunter/ a person who is cranky by nature didn't take their meds etc. Also there are young guys running these cars that need help. They are the ones here I would imagine that really don't need to be attacked. But yes the place (these forums) has changed I suppose people in general are fed up all around. My advice to anyone is get a Chilton manual or go to Allpar do the research learn how to read the wiring diagrams know what power ground is and which side of the circuit is switched know ohms law. Alot of times you can wiggle wires and see something happen that's called a wiggle test etc. generally if something doesn't work check fuses first start easy then work your way up to shooting wires. I see alot of folks starting with the hard stuff first it shouldnt be that way.
