OP here with an update. I got a prewired harness and popped in Gibson Burstbuckers that I've had sitting in the closest untouched for years. Firstly, the stock wiring was pretty bad looking. What was worse was that the bridge pickup had 3 of the 4 mounting holes with a misfire! As in they drilled in and made a hole that was a little off and had to redo another one. I filled them in with toothpick pieces and it's fine now but wow.
I also replaced the stock plastic nut with a bone nut and had to set it all up of course, which I did myself. It plays and sounds really nice! I did however wire it up for independent volume knob control and I think I'm going to switch to the dependent wiring that when in middle position, you kill the volume of one pickup it kills the sound. I can see the benefits of independent control in that it gives a lot of tonal options but I'm just not used to it.
