Yep I also installed the 273-060 buzzer, and I moved it outside the fuse box. I can hear nothing when the buzzer sit inside the fuse box in a noisy environment, now it works perfect. Attached a picture how I connect the wire to the outside of the fuse box, I think this is the best way to do it, going through one of the rubber outlet so no chance for the water to get in the fuse box (the white wire)
