What is this thing I found in my honda st1300?

Found it Velcroed in to the rear right saddlebag not wired to anything. The larger box has "r/a" and "f/a" ports as well as "port 1" "spdomtr" and "remote". The port 1 was wired to another box with 3 DC electrical ports and on the other side, a rusty silver box and red and black (power?) wires coming out.

The smaller box says "Able 2 products company" and there's no text on the larger box or it is covered up by Velcro which I'd rather not remove if I don't have to. Any ideas?

Thanks in advance, best answer will be awarded!

The smaller box is just a power accessory box, I found it here. Still have no idea what the bigger box would be used for What is this thing I found in my honda st1300 - 1

Able 2 and Show-me products have a line of light flashers and sirens for commercial/police vehicles.

Unmarked police bike, did you buy it at an auction?
