Painless wire harness install (MORE PROGRESS)

RedFish said

In some cases you will find the seperation occurs in the fuse box. So a group or section of fuses on each of the wires. That only improves safety. Catastrophic failure of one doesn't take out all of them. Example.. front end collision takes out headlight circuit all the way to the ignition switch yet dome lamp and brake lamps live on. Hope that makes some sense.

this has me confused..... are you saying that the fuse box already separates my circuits so i don't need to seperate my power supply from the starter power post with my junction box? I am running the separate junction boxes for power and ground to the under side of the dash in order to 1.) eliminate the wires going thru the fire wall 2.) running a ground junction box that is wired directly to the battery negative terminal eliminates the chance of bad chassis grounding. This is all in an effort to keep as much hidden as possible.
