the previous owner had something mounted on the roof that connected to that plug. they don't come like that from the factory. they probably didn't feel like taking everything apart so they just left it.
is there a switch that looks out of place somewhere in the car?
see if theres any extra wires by the battery or fuse block.
The previous owner might of took the wire harness under the hood for the roof plug
