Finishing up suspension and I decided to make my own wiring harness

More suspension work done this past week. I got the uprights on along with the brake rotors and calipers. A few more lines to hook up and the brakes will be done. I decided on making my own wiring harness, more for the experience than anything else. I’m trying to figure out where to start. I layed it all out on a board with the wiring terminus pretty much where they are layed out in the car. I categorized all the colors, gauge of wire and the style of terminal along with the vinyl sheathing that cover all the wire. Next step is to locate all the supplies and in the meantime cogitate where to even begin. Should be fun though.
