Hello, does anyone have the installation instructions for the Wiring Harness Cotton Braided 1940-1946 Chevrolet from jim carter? I bought my 46 chevy truck with this harness and I upgraded to a 12 volt system with new ignition switch and light switch and I having trouble with hiring up the light switch. For example my brake lights only work when the headlights are on. And there are some wires labeled 4 and another labeled 8 on the light switch that I can not trace back to anything.
