I have fixed this for people hundreds of times. Nothing to be embarrassed about- most of the time you can't tell the limits until this happens. Now, people are often derisive about gadgets that Stewart- McDonald comes up with. But, if there is enough free length to the wiring, their little pickup connecting jig is helpful. I threw a pair into an order to add to my many guitar specific gadgets and played with them and they are simple and can be helpful. The real secret to re-connecting a humbucker is having good feel with the screwdriver that lets it float in the hand. Then when you hit that sweet spot where it engages, you don't lose it or crossthread it- or, worse, strip the threads.
