I work for an automotive OEM. typically, only a few wire harnesses are used to cover all the different potential options. Each wire harness is tested by the vendor to ensure the connectors and wires are good.you could probably cover each 5th wheel with 2 or 3 harnesses (or just 1), and break TT into short, medium, long. Yes, you'd give away some wire, but it would have to be a LOT cheaper than random build **** they do
