I went down a rabbit hole when I discovered Obsidian Wire mods.
They involve all the normal parts: capacitors, resistors, push-pull pots, 5 way switches, capacitors, but...
the ingenious thing they have done is create a PCB to mount these things (via ribbon for the 5-way) and put these spring clamps--like you use when breadboarding circuits,--on the PCB, so all you need to do to install new pickups is insert the wires in the spring clamp.
