We have a 1950 lincoln that is basically all original. The wiring is in horrible condition, everything is still connected but the cloth insulation has long since disappeared. I'm going to just completely re wire everything instead of patching one system at a time and since I'm doing it I'm going to convert to 12v neg ground. Does anyone have an advice on which method I should use. Right now I'm leaning towards just doing custom wiring, basically a harness at a time so it can be really clean without any extra stuff to cut off and I can run it the way I want. Or I could go with one of the complete kits but their "universal" so I'm sure there will be a bunch of things I don't need. I'm comfortable doing either but I'm not sure if I'll save money with one. What have you guys done?
