So I got the pickups installed tonight, went mostly smoothly. They both work, couldn't do a proper sound test afterwards as it was getting late, but they both work and I don't hear any weird buzzing/clicking/static/etc. so that's a good sign. One thing I did notice is that if I have the pickup selector in the middle position, and I lower one of the volumes on either the bridge of the neck pickup, the entire volume seems to go out. Maybe it was always like that, or maybe I reversed a wire when I wired up the pickups to the mini-5 pin DIN connectors? I also hardly use the neck pickup is the truth of the matter. When the pickup selector is in either the bridge or neck position it seems to work as expected. Here's a photo of the pickups installed.
Thanks to everyone for their suggestions and tips! Very friendly forum here.
