Is there such a thing as a guide to what wires are routed where? For instance, the brake lights, where exactly is the wiring harness routed? If there are three wiring groups passing through the same area, what wires are in each of the different groups?
Does that makes sense? Is the information available?
Thanks.

Get a Haynes manual. It has detailed wiring diagrams for the entire electrical system.
