So I can pretty much do everything and am all self taught through books and online resources but I have not done electrical. I am building a complete shell and have a couple other cars I can look at but really want to know how to wire a car, build a harness and understand how all the pieces work. I know there are essentially four harnesses and where they go but how does it all work and come together. Any recommendations on a good book or site that breaks it all down. Doesn't have to be a porsche book, just a great book on electrical and wiring a car.
