There are a few possibilities for this and the ignition switch was my initial thought but you mentioned replacing it so I did not go in that line. There is a possibility the replacement switch is bad as well and we shall start with the basics.
Get a test light or DVOM.
At the igniter or EFI resistor, check the Black/Orange wire for battery voltage with ignition switch turned on. There must be battery voltage. If available, start engine and if it stalls, do not turn off ignition key, recheck the Black/Orange wire for battery voltage.
Turn on wiper or turn signals to see if they works.
At fuse block # 1, check the ENG fuse (15 A) for battery voltage.
At ignition switch there are 6 wires. Do you have battery voltage at the White and White/Red wire?
