GPR-1M wiring diagram

[WeirdBits]

This layout basically matches, except it uses push/pulls for coil splits. Just wire in your mini-switches instead.

Typically the 4-wire kit pickups will match up with that diagram as:
Black = north start (hot)
White = north finish
Red = south finish
Green = south start (ground)

(the above is just a general guide, different kits and production batches can vary wire colours etc)
