Default What is this black box connected to my wiring harness?

Found this under my ignition module when I was removing it. I'm the 5th owner of my 2005 1200XL Custom Sportster.
It was taped poorly and does not have any identifying marks other than the number 4904 as pictured below


4904 is the only identifying mark
How it was connected to my wiring harness

Not knowing where the wires go, I would guess its a blinker relay of some sort. Remove it and see what stops working then plug the ends into each other. See what happens.

Looks like an Auxiliary Brake light / Running Light / Turn signal conversion module.
Take it out, and plug the loom together and see what happens to the tail/turn lights.
