Hi , it's hard to say what two wires are, they maybe something to do with the data tool alarm, maybe a seat switch wire ?. I would start by seeing where they go which may require removing panels Etc. If everything at the back is working I wouldn't worry too much but if they are live cover them up to make sure you don't blow any fuses .
If the LED's are just a bulb replacement there shouldn't have been any wiring mods so changing them back to normal bulbs should be easy enough .
