I'm an old electrician of 35 years. A wiring diagram can instantly identify any wire. Some diagrams also show wire routing. I have lots of testers, voltage lites, and flashers, but nothing beats a factory diagram. Some times there is a circuit that is not used on a vehicle. I some times use those wires for other purposes. I use lots of Bosch type cube relays as well as aircraft manual reset breakers. Frank
I have seen a lot of different wiring diagrams for the older vehicles.
All of them show where the wire comes from and goes to, but I have never seen one that showed the route it takes to get there.
Also none of them show where the components are actually located.
I am a master electrician as well.
Fortunately, for my engine swap, I'm pretty good at puzzles! Motorcycle schematics are great, usually in color and they show the entire harness in one shot, so you can trace things easily. Why do auto makers make things so hard? My dad has a diagram for his '73 Pantera that is in color, and complete from one end to the other.

I have been rewiring my head lite switch. I have been trying to discover where the wires connected to the switch are going. Using a jumper, I have discovered the park lites, head lites and dash lites. There are 8 connections plus a very large maybe #10 supply wire with 12volt. Any hints and colors of same of conductors is appreciated. Frank
