making wiring harness from scratch

I used to build wiring harnesses in the Navy for weapons systems. The easiest way to get it right it was to lay out an example harness on a sheet of plywood, use larger nails to hold the harness in position on the out sides of the harness run like a guide of sorts. draw out the individual wires where they branch off and label them on the wood. Use a finishing nail to mark where the harness wire terminates. Then after removing the example harness its a simple matter of running or laying the wires of the proper color coding and take a couple turns on the nail where the wire should terminate. There are probably simpler ways of doing it but this was a sure fire way of getting it right every time.

Of course this could be used over and over so if you decide to hook us up and produce some extras you would be set up to do that!
