"Recommended" wiring is fused power from the battery to a relay, which is controlled by the ignition switched connection. Power out from the relay goes to the switch and then to the passing lights.
Slight variation would be fused power to the switch and then to the relay.
The fuse is somewhere between the battery and passing lights.... you'll have to trace it. Start under the seat because most people would put the fuse there for easy access to replace it. Easier there than inside the fairing.
