What you want is a buss bar and some of these buss bars also double as fuse block and you wire all your lights and gages to it and one side of the buss bar is all wired as one and gets wired to the battery + side. The single pole alternator get a 12 ga wire from the back of the alternator right to where the positive connects to the starter. The Delco single pole alternator has its own regulator built in. Now some of the buss bars don't have any thing fuse about them but allows you to tie in most of what you want to run and you just install in-line fuses.

could you direct link us to a drawing with a parts list? I am trying to get a 1942 chevy truck running again and am running into the same issues.
