can't figure it out!!!
 

Im pretty new to the diesel world. I just bought a used 08 Cummins 2500. Ive been around vehicles my whole life since my dad owns a junkyard, so I can do some mechanical work. On the truck I did h&s mini Maxx, full deletes with turbo back exhaust. S&b intake. Well while I was hooking up the mini Maxx under the dash and tucking away the wires I came across a little black box. It has no brand markings, only various sn #s and others. I've searched everywhere and have not found a thing on it. This little box looks like a flash drive that you plug into a computer. Has 2 wires that connect to the back of the obd port, with maybe 6 other wires that are cut. Red and green light that are on. That's all that's on it. Truck runs great, everything works. I just can't figure out what it is and it's driving me crazy. Any help would be greatly appreciated

Could be another programmer.
can you post a pic of it?
