There is logic behind the madness. Everything labeled 1-10 will be accessories (Keyed power) , 20-29 Ignition, 30-39 Radio (Which has its own ground for all the shielding wires)

Each circuit breaker and switch is individually wired. (Still just laying things out here, and testing the dash template)
