Way too complicated. KISS logic is the way to go.

No relays, it's all solid state with built in fault detection that automatically cuts power to a circuit in the event of a short. Read the manual here. It shows the max load for each circuit in one of the diagrams. With his setup, near zero load is going through handlebar switches. No relays or fuses required either. The downside is that the only replaceable part is the whole unit.

EDIT: I just looked up the max loads for each circuit:

L+R turn signal circuits 10A (!) each
Horn 10A
Starter 30A (enough to go straight to a Valeo or Bosch solenoid w/o starter relay)
High and low beam circuits 10A each
Brake light 10A
Ignition/Aux 18A

All switches only take .01A, so very small signal wire can be used.

Agreed. I didn't elaborate further on the fact that I DON'T like that function and wish it could be disabled.

Great stuff. Thanks

It's the zero load through the switches that causes most problems on vehicles. At least with a bit of current behind it the crap is generally burnt of the contacts.
