Ken, you should immediately contact Donald Erickson of Lark Works in Stockton, KS. He makes Studebaker wiring harnesses exclusively. He's very knowledgeable, and has equipment to make vintage wiring, even to weave cloth covers. You probably have to wait for a couple months, but since he is a graduate of McPherson College's 4 year program in auto restoration, he's quite in demand. http://www.larkworks.net/
