LS Swap guys…wiring routing question

[SilverGT3RS]

I’m going to go ahead and move my battery to the rear frame area on my 67 C10. I pretty much know how to run the wires and what sizes the wires need to be. However, I’m struggling to figure out the best place to terminate the hot lead and bus connection to feed the alternator, starter, various relays, and fuse panel.

Obviously I can bring the wire up the frame to the front firewall, install a 2-3 terminal bus there and carry a feed wire to the drivers side to feed my fan relays and fuse panel. I was just wondering if that’s how you guys are doing it. I saw a few YouTube vids where guys were setting their bus connections in the frame near the headers…I don’t think that’s a smart set up.

Any opinions or examples of how guys ran their wires on a relocated battery?
