Finish Wiring of a Stand Alone Harness

[bigmoe]

I'm on hold while my truck is away at paint for the next several months. I have the stock engine harness I'm going to rework. I have instructions for the fuse block to add to the end of the new harness. I'm just trying to wrap my head around the rest of the engine compartment. My 65 is bare. I need to buy a main wiring harness to wire the whole truck - lights, dash, most of it no big deal, just pondering about the engine compartment because some of the original wiring will not be needed with the LS engine harness replacing it? Starting at the battery and where to go first. Starter? Do I need a main fuse/junction? Where to come off of to feed the main fuse box. Voltage regulator? or is there one built in to the LS alternator? Neutral safety switch? Some of the stuff I'm pondering.
