What is this thing in smuggler box? 1971T

I can't figure out was this is?
Attachment 549507

I think it may be a motion sensor for an aftermarket alarm system, with a sensitivity adjusting screw next to the side connection on top. I recall them as an aluminum case though... Might be wrong. Where do the wires head off too?
