Finals are over...

Now it's time to build a new wiring harness. Next week I'm going to take my old harness off and start building a new one from scratch. I'd love it if anyone who has done this before would like to give me a couple of pointers or share any wisdom. I'd like to go as minimalist as possible to keep it simple. So if anyone out there would care to share their thoughts on how simple I can make this, please feel free to chime in. Thanks

Try to get the same colours of wire, that way you will know what is what the next time you have to check/fix something. if you use all one colour wire, the factory diagrams would be worthless to you;)
