I don't think I would dare start a wiring job like that. For anything that is more than just basic stuff, I also got a mate that does it for me. He explained the whole thing to me many times but I simply forget. Or lose interest.
For me, the whole thing with swapping pickups, changing the wiring, having different guitars, amps, etc. is just for fun and to learn more. I don't learn well by reading (about guitar stuff) so I prefer to test and do as much as I can myself. In time, I've learned a lot and definitely enough to stop caring about which guitar/pickup/amp/fretboard radius/etc is best and stuff like that.
For professional musicians, it's a different proposition but for a hobbyist like me, anything goes, depending on the mood. Microphonic pickups too. Why not?! If you like them, good for you. And if you change your mind and change the pickups again, that's fine too. Tastes change.
But I do hate a badly setup guitar and especially a dirty guitar! Cheap or expensive, it doesn't matter. That drives me insane.
I wonder what that mate of yours would say about my wiring?! (I'll speak to my friend on Sunday when we play).
