Has this happened to anyone else or am I just on an unlucky streak?
The jb4 is passive and can't hurt anything. Your shop is probably clueless. I'd get the car out of there before they run up a huge bill on your tab for what should be a 5 min fix. Send bms photos of your wiring and they should be able to point you in the right direction.
