What wires can be removed after LS swap?

[Ghost's68]

I should be more clear, I only want to remove wiring that run in the engine bay, from bulk head to its connection. Ie. bulk head to external voltage regulator. Bulk head to oil pressure switch. Since it’s LS swapped I’m guessing I no longer need much of those wires.

if you show me straight pictures i may be able to help identity some wires. i removed the original harness and have it laying in my truck. the first pic, (green wire) is for the horn. it goes to the ram style horn. i saw that you removed the extrenal regulator. i am running an 5.3/700r4. the pink wire is for +12v switched power. Red is for the +12V, which is connected to junction block. have you gave power to your engine yet? good luck.
