About to start working on rewiring my '49. It has been converted to 12volt. It still has the original 6v cloth wrapped wires (in poor condition). I intend to replace the fuse box with an ATC box, and add a few extra accessories.

Main question is what gauge of wire should be used to replace the following circuits:

Starter to Coil
Horn Relay
Headlights (will utilize relays)
Front Park/Turn Lights
Rear S/T/T
Dome
Dash Lights/Gauges
Cig Lighter
Alternator
Fog Lights (with relay)
Fuel Sender
Heater Blower Motor
Voltage Regulator
2 channel Amplifier

I want to make sure and not underpower anything, but also not over-wire. I have a chart that maps out the gauge of wire to distance per amps used. Only thing is I have no idea how many amps some of these items would draw. Thanks in advance.
