I'm more used with schematics for wiring harness, but these drawings always contain a table of the connections from a connector to some others with pin numbers, wire numbers and theirs splices. Once you have all the tables of each wiring of a given vehicle, you can rebuild the whole assembly and at will you can describe a given functionality. I've done this job for a manual repairs of a self-propelled harvester. Unless I miss something, one could the same by this way. > > This is sometimes served by a "block diagram" rather than a schematic. > In such a diagram, you omit all of the power-supply and ground > connections, and just focus on buses, chips, and the most important > control/enable lines.
