Well there was a system in there he removed to sell. Maybe he did damage the wiring.This is am odd problem for sure. It isn't completely impossible this is happening, but know that it is extremely rare. You might have a wiring problem in the steering wheel. Or maybe if someone was messing around trying to add to the system and damaged it.
Or it could be just normal power draw, and you battery is weak like Valpo stated.
That is the likely source of the drain.there was a system in there he removed to sell. Maybe he did damage the wiring.
