thats the S2 mira default wiring, think its same for other S2 22 models with a 3 way and 1xvol 1xtone
the wire coming in from the top right is the bridge pickup wire, with series coil tap green/white going to RH terminal on tone pot - (not the lowest row of lugs on the pot, it looks that way from the photo but it goes to the terminal above where that black wire is soldered - so the taps are soldered to the row of lugs beneath where the resistors are connected); the hot red wire goes to the 2nd terminal on the 3 way, from the left in photo.
The neck tap goes to middle lug (same row as described above) and red hot goes to the second terminal from RH side in photo on the other side of the 3 way wafer. As you can see I don't know the terminal numbers, just monkey it from the original photos
