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.
