It was simple. I removed the top back-half of the sander's body, unscrewed the old electric cord from the internal assembly, removed he cord, and replaced it with the new cord I bought from you, reattached the terminals, replaced the top half of the sander's body, and voila! Done. The sander worked perfectly.
