I rewired my 71 Duster. I broke out the circuits into about 20 some different fuses. With the blown fuse indicators, I can tell what is the problems without tearing into the car to find the problem.
But then again, that's me. I doubt many others have done what I have

I've actually jumpered two new fuse boxes to the original. One for switched and one for non-switched power for things I'm adding. For non-switched I jumpered off the spotlight lug since I don't have one and the switched I jumpered off the rear window defogger lug, since I don't have one.
