Twins / Re: 1959 A10 GF Wiring Loom

I would always over engineering the wiring. When I re-designed the new loom including new equipment, I added all the loads in Amps on each wire, added for the circuit and doubled them and got the appropriate wire. I find it useful to design in Fuses so if you get a problem 1. Not everything goes down and 2. you know better where to look.
I don't like AWG American Wire Guage, Europe uses the diameter and number and size of copper strands.
I use a chart as below
AWG Diameter Area Resistance Max Current Max Frequency
[inch] [mm] [kcmil] [mm2] [mΩ/m] [mΩ/ft] [Ampere] for 100% skin depth
