Voltage test to find incoming. Tone generator or 9v battery to identify outgoings. Alternatively, short out live/neutral on the switch wires and continuity test. Usually can figure out most of it before testing.

Here in NZ it's mostly tps/romex which, by the looks of it makes it easier to figure out.
