Mystery part

Anyone happen to know what this is? It was hooked to the power & ground of the radio in my truck. Power filter maybe?

Bob you mean the black box or the white one? I had one of the Black ones and it is a supressor and fuse combo, you can open it and see but I think thats what it is. Tha white one is just a fuse holder.
Good luck!
