There's more info in my 68 build thread, but here are a few details from what I did:
-I reworked my LS harness myself. Consolidated all the pink (keyed power) wires which include injectors, coils, sensors, etc. and merged them into a few wires which I then routed through a firewall bulkhead I bought from American Autowire. From there, attached wire inside the cab to a buss bar. Power for this buss bar came from one of the 30A keyed power accessory circuits from the American Autowire chassis harness.
-Consolidated all the orange (constant power) wires and ran them under the carpet from the PCM to an Autowire battery feed accessory circuit.
-Extended all wires from the LS harness that run to the PCM so that I could run that main branch of wiring down the transmission, through the trans tunnel, and into my center console. I put the PCM and OBDII port in the console where it's dry and hidden.
-I don't have a separate fuse block for the LS harness. It's cleaner to use the accessory circuits from American Autowire to power that harness.
-The only fuse block I have outside of the Autowire is for my fans and fuel pump in the engine bay.

Any specific questions, let me know.
