Hey. I've tried to replace my old pups in rga8 with some d activators. The problem is that there is this 3way switch "cor-tek 3p" and i havent found any wiring diagrams for it. Atm works the switch like "in the neck position works bridge and neck pups, same in the center position, and in bridge position works only neck pup so can't get bridge pup working alone. Any tips or diagrams would be apreciated.
