Vigier Guitars

Hey guys,
I know the Shawn Lane contains a Schaller Superswitch E but am wondering which coils are being split in the 2nd, 3rd and 4th position... Not sure if it is the bridge inner or outer etc. Tapping with a screwdriver did not help because I could hear some noise from tapping both coils so it as hard to tell !!
Also is the Middle pickup SOUTH (RWRP) or North polarity ??  
 
Thanks

Basically I want to make sure we have this config:
position 2: Bridge inner coil (Slugs - North side) + Middle
position 3: Neck Outer coil (Screws - South) + Bridge Inner coil ( Slugs - North)
Position 4: Neck inner coil (Slugs - North side) + Middle
