Back in the old days the elect tech-repairman did not use those parallel line diagrams in the factory . We had large blow ups of the ones on the Hammer website. there is a link for the wiki colbalt327 posted above. or google hammar mustang wiring diagrams. both the Hammer pictorial shows a black groung wire to the CVU and down the page, the schematic shows the CVU grounded. Those parallel line diagrams made it possible for the draftsman to get everything on one page, I reduced the labor required to build a wiring harness 30 % by building harness per the print , then laying out the harness so it looked like a tree on a tilted sheet of plywood, it made routing the various wires a lot faster and final installation of the harness was easier.
