A car’s electrical system can be a challenge for a do-it-yourself hobbyist. That’s why car magazines—for about as long as there have been car magazines—have covered the topic to help enlighten shade-tree mechanics.
For instance, Hot Rod magazine published an article in its June 1963 issue called “Wiring Made Easy” to illustrate the basic tools, hardware and steps needed to wire a hot-rod project. But the car in the opening photograph wasn’t just any hot rod. The subject car was the XR-6—a futuristic, built-from-scratch roadster that was the brainchild of Hot Rod’s LeRoi “Tex” Smith to “investigate the uses of modern ideas in hot-rod design,” as Smith described it. The XR-6 would go on to appear on the cover of Hot Rod’s August 1963 issue and also nab the coveted America’s Most Beautiful Roadster award at that year’s Oakland Roadster Show.
