The plug is hanging we’re you change bulbs passenger side on fiat 500 lounge 1.2 2014 .could it be an auxiliary plug for fog lights which aren’t fitted to this model? Thanks Martin
Martin, you are correct. This is, indeed, for the fog light; and you've got one more on the other side. OEM uses the same/similar harness for all cars. Put a cap over it, in case you might want to install the fogs in the future.
