Well, I don't have the clicking of the relay sound, however whenever I hit the brake pedal, it triggers the door locks and flashes my LED DRL's at whoever's in front of me. I have been driving with my headlights on more just to avoid flashing more people, the door locks constantly unlocking is very bothersome and has me worried about burning out my door lock actuators. I called 12volt, it took me 3 attempts before someone actually answered, but the lady seemed familiar with the issue and said she's sending me a new 30 pin wire, so we'll see if that fixes the issue. If it wasn't 20 degrees outside I would unplug the unit all together...
