I completely rewired my 46 WC in the past year with cloth covered wire trying to closely follow the factory specifications. When I added turn signals and some other accessories that all went out the window as far as color correct, but I stayed with cloth covered wire on everything and it's totally done from connector to connector. Have anybody considered using a reproduction harness from any source? Knowing how much I spent on wiring, terminals, shrink tubing, etc., and how much got wasted I'm not so sure I wouldn't have been better off with a harness already built and complete. I've been told this company is about the only one that makes point quality harness yet.
