Wire diagram
 

Checking my headlight diagram because they aren't working. But what are the boxes that the white wire leads too from the headlight? Where are they located on the bike?

The white boxes are connectors. That'll be the right handlebar switch connector. It notes that it's a mini connector, black in color, 9 pins.

Check next to the fuse box. There'll be several connectors held in place by a piece of sheet metal. It should be there

For what it's worth, I'd check fuses and confirm grounds, then check the headlight switch itself. Given that these things are out in the elements they can definitely get a bit crusty

Curious to see some pics of the bike

Oh yeah oops. Up here in the wastes it's been so long since the snow started that I forgot what side the headlight switch is on. You're looking for the left handlebar switch connector obviously
