About 15 years ago I wired a new aftermarket stereo into my *1978* Pontiac Bonneville, and I wired the radio'* ground wire to a harness wire that measured as ground, but was really the wire that goes +voltage for the light in the factory radio when the headlights are turned on.
Radio worked fine until it got dark out, I turned on the lights, and shorted out the circuits to the dash lights, the taillights, and the radio. And yes, I got pulled over and received a "fix-it" ticket.
I see you got your wiring fixed already, but your symptoms gave me deja-vu. I don't know if you made any changes to your car right before you had your problem, but if you did, it might have been something similar.
