Stingray guitar 3-way toggle diagram

Trying to rewire my great Stingray guitar with P90s and want to know how the switch is wired, which color is neck, which bridge, define all wires and connections. Switching out the circuit board/pots to same value freestanding pots and cap. G75840 is the serial, 2017, I think; got it from Willcutt. Any help much appreciated.
