Los Control, thank you for the great advice, you are correct, the old wire is taped up cloth wrapped stuff. I just replaced the main battery cables as the cloth was worn through in a couple spots and bare wire touching the frame. I love that it is so original and unrestored for the most part and want to keep it that way, but safety and protecting it from burning down my garage is more important to me than being a true original-parts truck in all respects. I have looked up the kits on DCM website, will do a little more digging for comparison. Has anyone here a preference for wiring kits and know which type have fuse protection?
This is the fuse I was thinking of that VintageAutoGarage recommends, but no info about how and where to install it
