That high beam wire comes from the dimmer switch,,,,,,,when you step on the switch, it sends power to the high beam filaments in your headlights and up to that socket,,,,,,start there. And those other gauges,,,,,well ammeters are useless,,,,,,,so are oil pressure gauges,,,,,,,,use the idiot light,,,,,,Temperature gauge and Voltmeter are important,,,,,,,and if you want to check those gauges out, you got 3 circuits in each gauge,,,,,,they all have to have power and a bulb
to light them up,,,,,,,,then each one has to have a sender to relay the information back to the gauge. I would see that each gauge has power from the ignition switch. The Temp gauge could be manual and so could the oil pressure. Get rid of that Ammeter,,,,,,you are just asking for trouble with it,,,,,,,it tells you nothing,,,,,,you could be putting 20 volts in the battery and killing it and the dumb ammeter says " look I'm charging",,,,,,,
