Showing my ignorance!!!!!

I have a small black plug in with a small red indicator light fastened to the bottom lip of the driver side dash on my 06 pony. I think it's tied into the security system somehow. Can anyone tell me what this little bugger is and what it's for or is it something someone has added in previous times???

Does it “Blink” when the car is off?
Factory key fob?

Maybe take a couple pics and post em here

Doesn't sound like it's a factory item. Possibly an aftermarket anti-theft/immobilizer system. A pic would help.
