I finally got brave and purchased a 1972 250C. All the electrics function, except for the horn and the foglamps. I started tracing the wires from the lamps and the horns. They travel together in a bundle up the front left fender, towards the fusebox, but end inexplicably in a couple of connectors that are not attached to anything
Living in South Florida, the foglamps are not a big deal, but the horn is. Any ideas?

Thanks!
