Where do each of these wires go?

Yellow Is 12 volts supply to switch
Red is 12 volts START voltage ( solenoid / start relay)
Blue and brown are ign 1 and2 on a 71 and 72 ( run voltage and cranking voltage with ballast resistor and points ) however u should have factory electronic ignition so since there are apparently only four wires ... One is run voltage and one is accessory voltage .
A DVOM will sort that out quickly or I can verify shortly at my break .
