It is hilarious that you said that. I have helped my best friend Mark restore three cars. A 67 Mustang, a 82 Chevy short bed stepside pick up and a 56 Studebaker Power Hawk. In all cases, he did most of the disassembly on the cars. He did not mark, or label anything on the wires when he took them apart. I label wires so carefully when I take them apart, that I know exactly how everything goes back together. It took me days to rewire the Mustang. And there were a couple of errors in the wiring diagram that I had to trace down. He did the same thing on the 82 stepside. It took me days to wire the stepside with a wiring diagram. And right now, we are 90% done with the 56 Power Hawk. All we have to do is paint it and put it together. And guess what? He took the wiring harness out of that car with no labels. Guess who gets to fix that? L O L.
