RE: headlight switch diagram (headlight wire color)
If you wire it in with the dash light/instument cluster wiring it will dim and brighten with the dash lights. I don't know the colors, but a few minutes with a test light at the fuse panel or light switch should work. Watch the test light dim as the dial is turned. Just a thought in case that isn't what the original intent was.
