Default What is this


So I just found this humming at the front left side of my 87 vette. Does anyone know what this is and why it might be doing this? It only does it when the car is running and I don’t know why or what this is. Any knowledge and help would be great

Looks like some kind of horn/siren for an aftermarket alarm system! I'd get rid of it and any non-factory switches/wiring associated with it👍

It is definitely an aftermarket alarm system siren. It looks like who ever installed it didn’t do a great job with it anyhow so best to remove and be sure to get all the wiring that goes with it
