Low voltage going to headlight…

I’m willing and eager to learn.
I was like you with just getting by with electrical. When I built my Hardtop,
I drew out all the wiring mods on paper with wire colors and gauge. I bought wire, terminals, solder gun and iron, some good crimper, book on electrical etc. I was dreading it. Once I got started it was enjoyable and rewarding. Who'd a thought.
